2. Description of the Related Art A water treatment apparatus including a purification treatment mechanism such as a sedimentation basin, a filtration basin, a water purification basin, etc. is usually opened outdoors under the open air. Therefore, the algae are likely to be generated and proliferated in the water to be treated by photosynthesis due to the sunlight radiated from the upper surface opening, which causes the algae to deteriorate the water quality. In addition, depending on the location conditions, there is a risk that dust, acid rain, etc. may enter from the top opening. These contaminants and algae become obstacles when performing a high-level purification treatment and increase the cost required for the purification treatment.

The present invention has been made in view of the above problems, and it is possible to easily perform maintenance and inspection of the treated water tank while preventing the generation of algae and allowing the power generated by the solar cell module to be used. The purpose is to do.

That is, according to the water treatment apparatus of the present invention, the opening portion of the treated water tank is shielded from light by the light shielding member to which a plurality of solar cell modules are attached, so that the generation of algae in the treated water tank can be suppressed. it can. Further, since the solar cell module attached to the light shielding member generates electric power, this electric power can be used as a power source for the purification processing mechanism section such as a pump and a stirrer. Further, the light-shielding member can be moved horizontally on the rail laid in the opening of the treated water tank with a plurality of solar cell modules attached, so that the light-shielding member can be used for maintenance and inspection of the treated water tank. Can be easily moved, and maintenance and inspection of the treated water tank can be easily performed. In the following description, when referring to a solar cell panel, it means a plurality of solar cell modules.

The water treatment device according to the present invention is a water purification facility for purifying water supplied from a water source or the like to treat it as drinking water or the like.
Say. The solar cell panel is electrically connected to the purification processing mechanism unit so that the electric power obtained by the photoelectric conversion unit becomes at least a part of the power of the purification processing mechanism unit. Part or all can be covered by private power generation. If the photoelectric conversion unit and the power unit of the purification processing mechanism unit are connected via the storage battery, it is possible to stably store the surplus power in the storage battery and stably supply power to the power unit of the purification processing mechanism unit. In addition, if the capacity of the solar cell panel allows, it is possible to supply surplus power to external facilities, etc., or as an independent power source that can replace the power source using other fossil fuels in the event of a commercial power outage due to a disaster etc. It can also provide motive power.

When converting the DC electricity obtained in the photoelectric conversion section of the solar cell panel into AC electricity, the obtained DC electricity is 1
It can be converted into AC electricity collectively in places, but the obtained DC electricity is put into a small power unit, for example, a power regulator of about 50 kilowatts, converted into AC electricity by the power regulator, and then the nearest transformer. It can be linked to the power system of the facility. As a result, since a plurality of power regulators having the same specifications can be used, maintenance and inspection can be easily performed and cost can be reduced.

The solar cell panel may constitute a part or all of the light shielding member. This is because of the structure of the purification treatment mechanism, the scale or capacity of the solar cell panel, the site condition of the water treatment device and the water to be treated. It may be set arbitrarily according to the nature and type of the. As a specific example of the solar cell panel that constitutes the light shielding member, there is a configuration in which a plurality of solar cell modules that are erected at a predetermined angle with respect to a horizontal plane are arranged. The solar cell module is fixedly supported by a supporting member such as a pillar or a roof frame material, and it is preferable that these supporting members are capable of withstanding a predetermined wind pressure load without rusting or falling of a mounting screw or the like.

[0009] The solar cell panel has a horizontal plane of 30 ° to obtain a high photoelectric conversion efficiency in Japan.
It is preferable to stand upright at an angle of 38 °. The optimum value of this angular attitude differs depending on the latitude and season in which the water treatment device is located, but for example, in the vicinity of 35 ° north latitude, when viewed throughout the year, 34 ° is the optimum value with respect to the horizontal plane. Further, the solar cell module may have a configuration in which its angular posture is changed in the vertical direction with respect to the horizontal plane, or may be changed in the horizontal direction in addition to the vertical direction. These angular attitude controls are appropriately achieved by conventional techniques.

In general, it is preferable that the inside of the water treatment device can be easily maintained and inspected in order to manage and maintain the treated water tank, for example, for exchanging the filter medium of the filter basin and periodic cleaning of the sedimentation basin. From this point, it is preferable that at least a part of the light shielding member is configured to be movable above the opening of the treated water tank. As such a moving mechanism, there may be mentioned a configuration in which a roller attached to a lower end of a supporting member such as a pillar or a roof frame member reciprocates on a rail laid along the treated water tank.

The light-shielding member comprises a solar cell panel, a fixing frame for mounting the solar cell panel on one plane, and a base for arranging a plurality of fixing frames at a predetermined interval and supporting above the opening of the treatment water tank. Further, a fixed frame raising / lowering means capable of changing the fixed frame, to which the solar cell panel is attached, to a state in which the fixed frame is erected at a predetermined angle posture with respect to the base body and a state in which the fixed frame is tilted backward and housed in the base body. If so, the height (thickness) of the light-shielding member is reduced by tilting the fixed frame to which the solar cell panel is attached backwards and storing it in the base body, so that the light-shielding member can be easily carried in and out. To do.
