Description

  The present invention relates to a water treatment apparatus that performs water treatment of water to be treated, and more particularly to a technique for performing chemical treatment of water to be treated by eluting the drug from the water to be treated.

Conventionally, in a water treatment apparatus that treats treated water such as domestic wastewater discharged from ordinary households and sewage such as industrial wastewater, a configuration for disinfecting the treated water is known. In order to solve the excess and deficiency of the sterilization treatment, it is necessary to perform water quality management to make the water quality after the sterilization treatment appropriate. For example, Patent Document 1 below discloses a technique for detecting residual chlorine contained in water after disinfection treatment using a residual chlorine sensor in a septic tank. According to such a technique, although it becomes possible to grasp whether the sterilization process of the to-be-processed water is performed appropriately, since an expensive sensor like a residual chlorine sensor is used, an apparatus cost becomes high. The problem arises. Therefore, when designing this type of water treatment apparatus that performs various kinds of chemical treatments including sterilization treatment of water to be treated, there is a demand to construct a system that simply and appropriately detects information related to chemical consumption.

  Therefore, the present invention has been made in view of the above points, and is effective in easily and appropriately detecting information regarding consumption of a drug in a water treatment apparatus that performs chemical treatment of water to be treated using the drug. The issue is to provide technology.

  The present invention is configured to solve the above problems. In addition, this invention is used suitably with respect to the water treatment apparatus which purifies the to-be-processed water, such as domestic wastewater discharged | emitted from a general household etc., industrial wastewater.

The water treatment device according to the present invention is a device that performs water treatment of water to be treated, and includes at least a treatment tank body, a medicine treatment region, a medicine container, a magnet, a magnetic sensor component, and a medicine information output unit.
The treatment tank body is configured as a tank-like body that accommodates a plurality of water treatment regions. The chemical treatment region is configured as a region for performing chemical treatment of water to be treated among the plurality of water treatment regions accommodated in the treatment tank main body. A chemical | medical agent container is comprised as a cylindrical member which accommodates the chemical | medical agent which elutes to the to-be-processed water of a chemical | medical agent treatment area | region, and extends longitudinally in the perpendicular direction. The term “tubular” as used herein is intended to broadly encompass columnar objects having a housing space (hollow space) therein, and typically includes a cylindrical member having a circular cross section, and a polygonal cross section. The prismatic member or the like corresponds to a cylindrical member. The drug is typically a solid disinfectant stored in a predetermined container and is configured to be eluted by the flow of water to be treated. This chemical can also be a component of the water treatment device. The chemical treatment of the water to be treated is performed by eluting the chemical into the water to be treated flowing through the flow path. The magnet is configured as a magnet that is accommodated in the medicine container and whose accommodation position is variable according to consumption of the medicine. In this case, the magnet housing position in the medicine container may be variable in accordance with the consumption of the medicine, and is configured to change substantially in accordance with the consumption height of the medicine in the vertical direction of the medicine container. There may be a structure which changes independently of the consumption amount of a medicine. As this magnet, there is typically used a double-sided, two-pole structure in which the N pole and the S pole are connected, and a magnet that is accommodated in the medicine container with the N pole and the S pole arranged in the vertical direction. .

  The magnetic sensor component is arranged on the outer surface side of the medicine container, and is configured as a sensor that operates based on magnetism received from the magnet. This magnetic sensor component is typically configured as a switch that is turned on and off by magnetism received from a magnet. The drug information output unit has a function of outputting drug information related to drug consumption by the operation of the magnetic sensor configuration unit. This medicine information output unit is typically connected to the magnetic sensor configuration unit by wire or wirelessly. The “drug information on drug consumption” mentioned here includes the presence or absence of the drug, the remaining amount of the drug, the consumption and consumption speed of the drug, the information that the drug has run out, and the fact that the drug is likely to run out. Information, information that drug processing is being performed normally, information that drug processing is not being performed normally, and drug consumption such as the timing and amount of drug replenishment associated with drug consumption Various information is widely included. In addition, regarding the output mode by the medicine information output unit, a mode in which characters, numbers, designs, etc. are displayed and output on a display unit, a mode in which sound, alarm, etc. are output to a speaker, and information detected by a magnetic sensor component It is possible to appropriately use a mode in which a signal is output to a remote monitoring device that remotely monitors a plurality of water treatment devices at a location separated from the water treatment device.

  By the way, the magnetic sensor component having such a configuration is a case where the magnet remains in a normal state, that is, when the upper surface and the lower surface of the magnet are maintained in a state perpendicular to the vertical direction, and the storage space of the medicine container is lowered. If the magnet is tilted in the process of descending, the magnet may not be reliably detected. In such a case, for example, even though the medicine has already disappeared, the information is not output, and it is difficult to replenish the medicine at an appropriate timing.

Therefore, in the present invention, in particular, the magnetic sensor component includes a switch operation in which two magnetic lead pieces arranged coaxially with respect to the vertical direction are opposed to each other with a predetermined contact gap at a lead contact, and a magnet is detected. Sometimes it is configured with reed switches that come into contact with each other at the reed contacts, and this reed switch is on the outer surface side of the drug container such as the drug container itself, the drug container fixture, the wall of the disinfection tank, the partition plate, the sedimentation plate, etc. It is set as the structure arrange | positioned with respect to the direction which cross | intersects the extending direction of a chemical | medical agent container. And the said magnetic sensor structure part is set as the structure which act | operates at the time of operation of at least 1 switch among several reed switches. According to such a configuration, even when the magnet is tilted in the process of descending the medicine container as the medicine is consumed, the magnet can be reliably detected via any one of the reed switches. It is possible to prevent leakage of the magnet. Further, when a plurality of reed switches are arranged in the extending direction of the medicine container, the remaining amount of medicine and the progress until the remaining amount of medicine disappears are grasped over time using the plurality of reed switches. This makes it possible to finely manage the remaining amount of medicine.

  Moreover, in the water treatment apparatus of the further form concerning this invention, the said chemical | medical agent container is comprised as a cylindrical container, Moreover, as for the said magnetic sensor structure part, several reed switches are extension of a chemical | medical agent container. On the same plane in the direction intersecting the direction, it is arranged at equal intervals in the circumferential direction of the medicine container, and the axes of the magnetic lead pieces of two adjacent reed switches relatively intersect with each other. Is preferred. According to such a configuration, a rational arrangement mode in which a plurality of reed switches are arranged in a balanced manner on the same plane is realized.

  Moreover, in the water treatment apparatus of the further form concerning this invention, the said magnetic sensor structure part is two reed switches in which the relative crossing angle of the axis | shaft of the magnetic reed piece of adjacent two reed switches is arbitrary. Are preferably configured to be similar. According to such a configuration, a rational arrangement mode in which a plurality of reed switches are arranged in a well-balanced manner with respect to the relative inclination between two adjacent reed switches is realized.

  Moreover, in the water treatment apparatus of the further form concerning this invention, the said chemical | medical agent is accommodated in the chemical | medical agent container in the state where the some solid chemical | medical agent formed in the solid form was piled up and down, and the bottom solid chemical | medical agent Are eluted and consumed in the water to be treated in the chemical treatment area in order, and a magnet is stacked on the uppermost solid medicine, and the magnetic sensor component includes a plurality of reed switches that contain the medicine. It is preferable that it is the structure arrange | positioned on the same plane of the direction which cross | intersects the extension direction of a chemical | medical agent container in the site | part corresponding to the lowest solid drug among the outer surface side of a body. When the magnet is lowered from the upper side to the lower side in the drug container by its own weight with the elution of the solid drug, and close to the plurality of reed switches, at least two magnetic bodies of the plurality of reed switches are used. When the lead pieces come into contact with each other at the lead contact, the switch is activated, and in this switch activated state, the medicine information output unit outputs that there is no remaining amount of medicine as medicine information. According to such a configuration, the user (owner) and the maintenance manager of the water treatment apparatus are output from the medicine information output unit according to the change in the accommodation position of the magnets stacked on the uppermost solid medicine. It is possible to recognize that there is no remaining amount of medicine or that there is little remaining amount as medicine information.

  As described above, according to the present invention, in the water treatment apparatus that performs chemical treatment of water to be treated using a chemical, the magnetic sensor component that operates based on the magnetism received from the magnet is coaxial with respect to the vertical direction. The two magnetic lead pieces disposed are opposed to each other with a predetermined contact gap at the lead contact, and are configured by using a reed switch that contacts each other at the lead contact when the switch that detects the magnet is operated. By providing a plurality of arrangements in at least one of the extending direction of the drug container and the direction intersecting the extending direction on the outer surface side of the drug container, information on drug consumption can be easily and Therefore, it is possible to construct a drug consumption information detection system that can detect properly and has high reliability.

As shown in FIG. 1, the water treatment apparatus 100 of this Embodiment has the processing tank main body 101 shape | molded in the tank shape, and this processing tank main body 101 has an upstream processing tank as a some water treatment area | region. 110, the disinfection apparatus 120, and the storage tank 130 are accommodated. Waste water that has flowed into the treatment tank main body 101 through the inflow portion 102 is sequentially processed in the upstream treatment tank 110, the disinfection device 120, and the storage tank 130, and the treated water flows out of the treatment tank main body 101 through the outflow portion 103. To do. In this case, the water treatment apparatus 100 may be configured as a purification tank that discharges the water that has flowed out of the treatment tank body 101 as it is, or the water that has flowed out of the treatment tank body 101 is used as a toilet or water for watering. It may be configured as a water reuse device to be reused. The treatment tank main body 101 here corresponds to “a treatment tank main body that accommodates a plurality of water treatment regions” in the present invention.

  The upstream treatment tank 110 typically performs a process of separating contaminants contained in the treated water from the treated water using solid-liquid separation means such as an inflow baffle (not shown). , Foam separation tank for separating foam from treated water, anaerobic filter bed tank for anaerobic treatment (reduction) of organic pollutants in treated water, aerobic treatment (oxidation) for organic pollutants in treated water It is constituted by one or a plurality of treatment tanks such as a contact aeration tank and a precipitation tank for precipitating and removing suspended substances in the water to be treated.

In this case, the output unit 220 of the water quality management device 200 can grasp output information at an arbitrary place by adopting a mode in which Internet connection is possible, for example.

  The treated water from which the disinfectant 122 is eluted in the disinfection device 120 flows into the storage tank 130. In the storage tank 130, the water before flowing out through the outflow portion 103 is temporarily stored, and the disinfection process is continued in this storage state. Accordingly, the storage tank 130 is referred to as a “disinfection tank” that performs disinfection processing of the water to be treated, and the above-described disinfection device 120 that supplies the disinfectant 122 to the storage tank 130 is referred to as a “chemical supply device”. Can also be referred to. The disinfecting apparatus 120 or the disinfecting apparatus 120 and the storage tank 130 downstream thereof are treatment tanks involved in disinfection processing (chemical treatment) of water to be treated. The “medicine processing area” is configured. When the water treatment device 100 is configured as a water reuse device, the water that has flowed out of the storage tank 130 is transferred to a toilet or a sprinkler, and when the water treatment device 100 is configured as a septic tank, It is discharged into public water as it is. In relation to this configuration, another tank such as a discharge pump tank in which a discharge pump is installed may be provided downstream of the storage tank 130.

  2 and 3 will be referred to regarding the specific configuration and operation of the drug cylinder 121. FIG. 2 shows a cross-sectional structure of the medicine cylinder 121 provided in the disinfection apparatus 120 in FIG. 1 before using the disinfectant, and FIG. 3 shows a medicine cylinder 121 provided in the disinfection apparatus 120 in FIG. The cross-sectional structure during use of the disinfectant is shown.

  As shown in FIG. 2, the medicine cylinder 121 of the present embodiment is configured as a medicine cylinder housing having a hollow accommodation space 121a, and a plurality of (four in the example shown in FIG. 2) disinfection in this accommodation space 121a. Agents 122 are stacked and accommodated one above the other. Moreover, this chemical | medical agent cylinder 121 is a cylinder of the cross-section circular shape extended in a vertical direction (tank up-down direction in the processing tank main body 101 in FIG. 1), and is provided with the lid | cover 127 which plugs up the cylindrical housing upper part. It is supposed to be configured. The lid 127 is attached to the upper part of the housing during use, and is opened when the disinfectant 122 is filled or maintenance is performed. The disinfectant 122 is configured as a solid disinfectant having a diameter smaller than the inner diameter of the drug cylinder 121, typically a chlorine-based solid disinfectant. When such a chlorinated solid disinfectant is used, a coating layer (for example, fluororesin coating) is provided on the inner wall portion of the drug cylinder 121, or the drug cylinder 121 itself is made of a chlorine-resistant material. It is preferable to ensure the chlorine resistance of the drug cylinder 121. The drug cylinder 121 here corresponds to the “medicine container” in the present invention, and the disinfectant 122 here corresponds to the “medicine” and “solid drug” in the present invention. In addition, a housing flow passage 123 through which water flowing from the upstream processing tank 110 circulates is provided in a lower region of the accommodation space 121a, that is, in a portion where the lowermost disinfectant 122 is located in the cylindrical wall of the drug cylinder 121. . The housing flow path 123 is disposed on the flow path 126 through which water that has flowed from the upstream processing tank 110 into the disinfection device 120 flows.

  In this configuration, the water to be treated flowing through the flow passage 126 is removed from the lower disinfectant 122 among the plurality of disinfectants 122 stacked vertically by the water to be treated flowing through the housing flow passage 123 of the drug cylinder 121. In this order, the water to be treated is eluted continuously and used for disinfection treatment (chlorine disinfection treatment) of the water to be treated. Further, in the present embodiment, the magnet 124 is stacked and placed (placed) on the uppermost disinfectant 122 of the accommodation space 121a. That is, the magnet 124 is supported from below by the uppermost disinfectant 122.

  In the medicine cylinder 121 having the above-described configuration, the disinfectant 122 is consumed by elution with respect to the water to be treated. Therefore, the stacking height L of the plurality of disinfectants 122 in the vertical direction (vertical direction in FIG. 2) gradually decreases. To go. In addition, as shown in FIG. 3, as the stack height L of the plurality of disinfectants 122 decreases (disinfectant consumption), the position of the magnet 124 in the accommodation space 121a is moved from above in the medicine cylinder 121 by its own weight. The magnet 124 is displaced downward, and the magnet 124 is lowered in the direction approaching the magnetic sensor component 150. That is, the magnet 124 according to the present embodiment is configured such that the accommodation position thereof is variable according to the remaining amount of the disinfectant 122 in the medicine cylinder 121. In this case, the amount of change in the accommodation position of the magnet 124 substantially matches the amount of medicine consumed in the vertical direction of the medicine cylinder 121. The magnetic sensor component 150 here corresponds to the magnetic sensor component in the present invention.

For specific configurations of the magnet 124 and the magnetic sensor configuration unit 150, reference is made to FIG. FIG. 4 shows a cross-sectional structure of the magnet 124 and the reed switch 140 according to the present embodiment.

It is supposed to be configured. The magnet main body 124a is a permanent magnet having a so-called “double-sided two-pole structure” in which N poles and S poles are connected, and typically has a cylindrical shape, a cylindrical shape, or an annular shape (donut shape). The The covering member 124 b protects the magnet main body 124 a and allows the magnet 124 to slide smoothly in the medicine cylinder 121. In the present embodiment, the magnet 124 is accommodated in the drug cylinder 121 in a state where the N pole and the S pole are arranged in the vertical direction. In this case, as shown in FIG. 4, the magnet 124 may be accommodated so that the N pole is down and the S pole is up, or the N pole is up and the S pole is down. The structure accommodated in may be sufficient. The magnet 124 or the magnet main body 124a mentioned here corresponds to the “magnet” in the present invention.

  On the other hand, the reed switch 140 constituting the magnetic sensor constituting unit 150 of the present embodiment is a switch called a so-called “reed switch” or “magnet switch”, and detects magnetism generated in the magnet body 124a of the magnet 124. Have a function of turning on and off. Specifically, the reed switch 140 has a structure in which two reed pieces 143 and 144 are enclosed in a glass tube 142 filled with an inert gas as shown in FIG. Each of the first lead piece 143 and the second lead piece 144 constituting the reed switch 140 is configured as a magnetic lead piece made of a magnetic material, and is arranged coaxially in the vertical direction. The first lead piece 143 and the second lead piece 144 are predetermined contact points at a lead contact point (a contact point formed by one end portion 143a on the first lead piece 143 side and one end portion 144a on the second lead piece 144 side). While facing each other with a gap, they are brought into contact with each other at the lead contact point when the switch is operated in which the magnet body 124a is detected in the detection region A formed in the medicine cylinder 121. The reed switch 140 here corresponds to a “reed switch” in the present invention, and the lead pieces 143 and 144 constituting the reed switch 140 correspond to “two magnetic lead pieces” in the present invention.

  Here, FIG. 5 is referred to regarding the specific operation of the reed switch 140 described above. FIG. 5 shows a cross-sectional structure of the magnet 124 and the reed switch 140 when the reed switch 140 of the present embodiment is in operation.

  As shown in FIG. 5, when the magnet 124 descends the storage space 121a of the drug cylinder 121 as the disinfectant 122 is consumed and the magnet body 124a enters the detection area A, the reed switch 140 is in an activated state (the switch is Entered on state) (reed switch operating state). Specifically, with this intrusion operation, the first lead piece 143 has one end portion 143a having an N pole and the other end portion 143b having an S pole, whereas the second lead piece 144 has an end portion 144a. Is the S pole and the other end 144b is the N pole, so that the one end 143a (contact) of the first lead piece 143 and the one end 144a (contact) of the second lead piece 144 are attracted by the magnetic attractive force, They contact each other in the gap.

In the present embodiment, when the reed switch 140 is activated, the transmitter 160 connected to the reed switch 140 via the cable 141 has no remaining amount of the disinfectant 122 or the remaining disinfectant 122. Information indicating that the amount is small is wirelessly transmitted to the reception unit 210 on the water quality management device 200 side. Based on the information received by the receiving unit 210, an output that prompts the user (owner) or the maintenance manager of the water treatment apparatus 100 to inspect the disinfection device 120 and replenish the disinfectant 122 in the disinfection device 120. The operation is performed by the output unit 220. The output information of the output unit 220 in this case includes the presence / absence and remaining amount of the disinfectant 122, the consumption amount and consumption speed of the disinfectant 122, information indicating that the disinfectant 122 is lost, and the disinfectant 122 is likely to disappear. Information indicating that the disinfection process has been performed normally, information indicating that the disinfection process has not been performed normally, and the disinfectant replenishment timing and replenishment amount associated with consumption of the disinfectant 122, etc. Various information regarding the consumption of the disinfectant 122 is widely included. In addition, regarding the output mode in this case, it is possible to appropriately use a mode in which characters, numbers, symbols and the like are displayed and output on a display unit, a mode in which sounds, alarms, etc. are output as sound to a speaker.
The output information here corresponds to “drug information related to drug consumption” in the present invention. Further, the transmission unit 160, the reception unit 210, and the output unit 220 here have a function of outputting drug information related to consumption of the disinfectant 122 based on magnetism detected by the magnetic sensor configuration unit 150 (reed switch 140). And constitutes a “drug information output unit” in the present invention.

  In the present embodiment, in place of or in addition to the wireless transmission structure described above, when at least one of the plurality of reed switches 140 is activated, the remaining amount of the disinfectant 122 is lost or the disinfectant It is also possible to adopt a configuration in which information indicating that the remaining amount of 122 is low is output by a field installation type output unit (drug information output unit). According to such a configuration, the user (owner) or the maintenance manager of the water treatment apparatus 100 installs the water treatment apparatus 100 that the remaining amount of the disinfectant 122 is lost or the remaining amount of the disinfectant 122 is low.

Thus, information on the remaining amount of the disinfectant 122 can be accurately detected by the reed switch 140.

  By the way, the magnetic sensor component 150 (reed switch 140) having the above-described configuration is configured so that the magnet 124 remains in a normal state, that is, while the upper surface and the lower surface of the magnet 124 are maintained in a state orthogonal to the vertical direction. The case is assumed that the housing space 121a is lowered, and the reed switch 140 cannot reliably detect the magnet 124 when the magnet 124 is tilted as shown by the two-dot chain line in FIG. Will occur. In such a case, for example, even though the disinfectant 122 has already disappeared, the information is not output, and it is difficult to replenish the disinfectant 122 at an appropriate timing.

A configuration in which a plurality of reed switches 140 are arranged in at least one of the existing direction (vertical direction) and the direction intersecting with the extending direction is employed. Then, when at least one of the plurality of reed switches 140 is activated, the transmitter 160 connected to the reed switches 140 via the cable 141 has no remaining amount of the disinfectant 122 or the disinfectant. Information indicating that the remaining amount of 122 is low is wirelessly transmitted to the reception unit 210 on the water quality management device 200 side. By adopting such a configuration, even when the magnet 124 is tilted in the process of descending the housing space 121a of the medicine cylinder 121, the magnet 124 can be reliably detected via any one of the reed switches 140. And detection leakage of the magnet 124 can be prevented. In addition, the remaining amount of the disinfectant 122 and the progress until the remaining amount of the disinfectant 122 runs out can be grasped over time by using a plurality of reed switches 140, and fine control regarding the remaining amount of the disinfectant 122 is possible. It is possible.

It is set as the aspect arrange | positioned by a space | interval. Specifically, when two reed switches 140 are used as shown in FIG. 6, the interval between the two reed switches 140 can be set to 180 °. Similarly, when three reed switches 140 are used as shown in FIG. 7, the interval between each of these three reed switches 140 can be set to 120 °, and as shown in FIG. When four reed switches 140 are used, the interval between the four reed switches 140 can be set to 90 °. According to such an arrangement mode, the plurality of reed switches 140 are arranged in a well-balanced manner on the same plane in the direction intersecting with the extending direction of the drug cylinder 121.

  Further, with respect to the disposition mode shown in FIG. 6, the two reed switches 140 whose interval is set to 180 ° are disposed so that the axes of any of the lead pieces 143 and 144 coincide with the vertical direction. The two reed switches 140 may be disposed on the same plane P1 as shown in FIG. 9, and one (front side) reed switch 140 may be The lead pieces 143 and 144 are arranged such that the axis L1 of the lead pieces 143 and 144 is inclined 45 ° clockwise with respect to the vertical line L0, while the other (opposite) reed switch 140 is provided with the axis of the lead pieces 143 and 144. You may employ | adopt the 2nd arrangement | positioning aspect arrange | positioned L2 inclining 45 degrees to the left with respect to the vertical line L0. In this second arrangement mode, the relative crossing angle of the axis L1 of the lead pieces 143 and 144 of one reed switch 140 and the axis L2 of the lead pieces 143 and 144 of the other reed switch 140 is 90 °.
