[Work procedure and LED on / off operation]
Hereinafter, an operation procedure when the septic tank S is cleaned by the sludge concentrating vehicle 1 having the above-described configuration and an operation of turning on / off the LED 120 in the flow path display panel 116 will be described.

<Original sludge suction work 1>
When sucking raw sludge from the septic tank S to the sludge tank 8, the suction / discharge hose 10 is unwound from the hose reel 9 and its tip is inserted into the anaerobic tank S ′ of the septic tank S. A short suction / discharge hose 14 may be used instead of the long suction / discharge hose 10.

  In the anaerobic tank S ′, usually, three layers are formed by the scum 200, the intermediate water 201, and the precipitated sludge 202 in order from the top (see FIG. 2). The suction operation into the tank 5 of each layer is performed in the order of the upper layer scum 200, the intermediate layer intermediate water 201, and the lower layer precipitated sludge 202.

  Since the scum 200 in the upper layer has a relatively high proportion of solid content, the scum 200 is sucked and collected directly into the sludge tank 8 without passing through the drum screen 11. In order to perform this suction recovery, the tip of the suction / discharge hose 10 is inserted into the scum 200 in the anaerobic tank S ′, and the vacuum pump 52 is driven. Further, by operating the intake / exhaust operation lever 59L toward the red first guide display 117c shown in FIG. 3, the intake / exhaust switching valve 59 is set to the switching position a, and the sludge treatment lever 77L is also displayed on the red first guide display 117b. Operating the sludge treatment switching valve 77 to the switching position a and operating the suction passage switching lever 73L downward to bring the suction passage switching valve 73 to the switching position a and the air switching lever 61L to the first red color. By operating the guidance display 117a, the air switching valve 61 is set to the switching position a and the hose reel opening / closing lever 79L is operated downward to open the long hose opening / closing valve 79. Note that the air release valve 69, the short hose on / off valve 80, and the on / off valves 85, 87, 89 are closed.

  It should be noted that there are three first guidance displays for guiding the directions in which the suction intake / exhaust operation lever 59L, the air switching lever 61L and the sludge treatment lever 77L should be operated in order to suck the sludge from the septic tank S to the tank 5 (sludge tank 8). Since both are displayed in red and are different from the color (blue) of the second guidance display, the operation of the levers 59L, 61L, 77L can be easily performed even by a beginner. In addition, the operator who is used to the operation is less likely to make an erroneous operation.

  When the various levers are operated, the suction side of the vacuum pump 52 and the sludge tank 8 communicate with each other, and the sludge tank 8 is depressurized. Since the sludge tank 8 to be decompressed and the tip side of the suction / discharge hose 10 communicate with each other, the scum 200 is sucked and collected from the tip of the suction / discharge hose 10 into the sludge tank 8 without the drum screen 11.

  At this time, since the detection state of the row L1 of the table of FIG. 6 is satisfied, the lighting control circuit 121, as shown in FIG. 7, the suction / discharge hose picture A10, the connecting pipe picture A90, the first sludge water supply pipe picture LED 74 on A74, sludge tank suction pressurization pipe picture A60, branch pipe picture A62, reaction tank suction pressurization pipe picture A57 and air switching valve picture A61 is turned on, and on sludge treatment switching valve picture A77 and suction passage switching valve picture A73. Some of the LEDs 120 are turned on, and the other LEDs 120 are turned off.

  Thus, by turning on / off the LED 120, an operator who works while looking at the flow path display panel 116 allows the raw sludge (scum 200) from the septic tank S to enter the sludge tank 8 through the suction / discharge hose 10. It is possible to visually grasp that the sludge tank 8 is decompressed by the vacuum pump 52 while being collected by suction.

<Original sludge suction work 2>
After the suction and recovery of the scum 200 to the sludge tank 8 is completed, the intermediate water 201 is sucked into the tank 5. The intermediate water 201 is sucked into the reaction tank 7 because the proportion of moisture is relatively high. In order to perform this suction, the tip of the suction / discharge hose 10 is inserted into the intermediate water 201 in the anaerobic tank S ′ from the above state. Then, by operating the suction passage switching lever 73L to the left, the suction passage switching valve 73 is switched to the switching position b. As a result, the proximity sensor 73-1 changes from ON to OFF, and the proximity sensor 73-2 changes from OFF to ON.

  When the lever is operated, the pressure-reduced reaction tank 7 communicates with the front end side of the suction / discharge hose 10 so that the intermediate water 201 is sucked and collected from the front end of the suction / discharge hose 10 into the reaction tank 7. .

  At this time, since the detection state of the row L2 of the table of FIG. 6 is satisfied, the lighting control circuit 121, as shown in FIG. 8, the suction / discharge hose picture A10, the connecting pipe picture A90, the tank connection pipe picture A72, the reaction The LED 120 on the tank suction pressurization pipe picture A57, the sludge tank suction pressurization pipe picture A60, the branch pipe picture A62 and the air switching valve picture A61 is turned on, and one of the LEDs 120 on the sludge treatment switching valve picture A77 and the suction passage switching valve picture A73 The part is also turned on, and the other LEDs 120 are turned off.

  Thus, by turning on / off the LED 120, an operator who works while looking at the flow path display panel 116 allows the raw sludge (intermediate water 201) from the septic tank S to pass through the suction / discharge hose 10 in the reaction tank 7. It is possible to visually grasp that the reaction tank 7 is decompressed by the vacuum pump 52.

<Original sludge suction work 3>
After the suction of the intermediate water 201 into the reaction tank 7 is completed, the precipitated sludge 202 is sucked into the tank 5. The precipitated sludge 202 is sucked and collected directly in the sludge tank 8 without using the drum screen 11 because the proportion of the solid content is relatively high. In order to perform this suction recovery, from the above state, the tip of the suction / discharge hose 10 is inserted into the sedimented sludge 202 in the anaerobic tank S ′, and the suction passage switching lever 73L is returned downward again, thereby the suction passage switching valve. 73 is switched to the switching position a. As a result, the proximity sensor 73-1 changes from OFF to ON, and the proximity sensor 73-2 changes from ON to OFF.

  When the lever operation is performed, the suction side of the vacuum pump 52 and the sludge tank 8 communicate again, and the sludge tank 8 is depressurized. Further, the sludge tank 8 to be decompressed and the tip side of the suction / discharge hose 10 communicate with each other, so that the precipitated sludge 202 is sucked and collected from the tip of the suction / discharge hose 10 into the sludge tank 8.

  At this time, since the detection state of the column L1 in the table of FIG. 6 is satisfied, the lighting control circuit 121 turns on / off the LED 120 as shown in FIG.

  Thus, by turning on / off the LED 120, an operator who works while looking at the flow path display panel 116 allows the raw sludge (sediment sludge 202) from the septic tank S to pass through the suction / discharge hose 10 in the sludge tank 8. It is possible to visually grasp that the sludge tank 8 is decompressed by the vacuum pump 52.

<Aggregation reaction treatment>
After the suction and recovery of the precipitated sludge 202 to the sludge tank 8 is completed, the intermediate water 201 sucked into the reaction tank 7 is subjected to a coagulation reaction process. In order to perform this agglutination reaction process, the air switching lever 61L is operated toward the blue second guide display 118a from the above state, whereby the air switching valve 61 is switched to the switching position c and is closed. , 87 are opened and the hose reel opening / closing lever 79L is operated to the right to close the open long hose opening / closing valve 79. Then, the reaction tank 7 is depressurized, and the coagulated liquid mixed with air is mixed into the intermediate water 201 in the reaction tank 7 from the coagulation tank 12 side, and the coagulation reaction is uniformly promoted by the stirring action by bubbling. Eventually, gel-like aggregated sludge (secondary sludge) is generated from the intermediate water 201 in the reaction tank 7.

  At this time, since the detection state of the row L3 of the table of FIG. 6 is satisfied, the lighting control circuit 121, as shown in FIG. 9, the aggregate liquid injection pipe picture A84, the atmospheric suction pipe picture A86, and the reaction tank suction pressure pipe picture The LED 120 on A57 is turned on, and the other LEDs 120 are turned off.

  In this case, an operator who works while looking at the flow path display panel 116 depressurizes the reaction tank 7 by the vacuum pump 52, and a coagulant is supplied from the aggregation tank 12 into the reaction tank 7. It is possible to visually grasp that the agglutination reaction process is performed.

<Separated water discharge work>
Next, secondary sludge water composed of the secondary sludge generated in the reaction tank 7 and the secondary sludge remaining without agglomeration is pumped to the drum screen 11. In order to perform this process, the suction / discharge switching lever 59 is moved to the switching position c and the suction passage switching lever 73L is operated to the left by operating the suction / discharge control lever 59L toward the blue second guide display 118c. Thus, the suction passage switching valve 73 is set to the switching position b, and the sludge processing lever 77L is operated toward the blue second guide display 118b, so that the sludge processing switching valve 77 is set to the switching position b. Further, the air switching lever 61L maintains the operated state toward the blue second guidance display 118a, thereby holding the air switching valve 61 at the switching position c and operating the hose reel opening / closing lever 79L downward. Then, the long hose opening / closing valve 79 is opened. Further, the open on-off valves 85 and 87 are closed. Then, the secondary sludge water in the reaction tank 7 is pumped to the drum screen 11 through the tank communication pipe 72, the suction passage switching valve 73, the connecting pipe 90, the sludge treatment switching valve 77, and the second sludge water supply pipe 75. The secondary sludge water is separated into secondary sludge (gel-like coagulated sludge) and secondary sludge (separated water) remaining without agglomeration in the drum screen 11, and the secondary sludge is discharged from the drum screen 11. And accumulated in the sludge tank 8. On the other hand, the secondary sewage (separated water) is pumped to the septic tank S by the submersible pump 11a through the sewage recirculation pipe 76, the sludge treatment switching valve 77, the raw sludge suction pipe 78, and the suction / discharge hose 10.

  It should be noted that in order to discharge the separated water (sewage) separated by the drum screen 11 to the septic tank S, three third guides for guiding the directions in which the suction / exhaust operation lever 59L, the air switching lever 61L and the sludge treatment lever 77L are to be operated. Since the two guidance displays are all displayed in blue and are different from the color of the first guidance display (red), the operation of the levers 59L, 61L, 77L can be easily performed even by a beginner. In addition, the operator who is used to the operation is less likely to make an erroneous operation.

  At this time, since the detection state of the row L4 of the table of FIG. 6 is satisfied, the lighting control circuit 121, as shown in FIG. 10, the suction / discharge hose picture A10, the sewage reflux pipe picture A76, the second sludge water supply pipe The LED 120 on the picture A75, the connecting pipe picture A90, the tank communication pipe picture A72, and the reaction tank suction pressure pipe picture A57 is turned on, and part of the LED 120 on the sludge treatment switching valve picture A77 and the suction passage switching valve picture A73 is also lit. The other LEDs 120 are turned off.

  Thus, by turning on / off the LED 120, an operator who works while looking at the flow path display panel 116 pressurizes the reaction tank 7 by the vacuum pump 52, and agglomeration reaction processing in the reaction tank 7 is performed. It is possible to visually grasp that the sludge water subjected to is pumped to the drum screen 11 and the separated water separated by the drum screen 11 is returned to the septic tank S.

  After the separation water returning operation is completed, the driving of the vacuum pump 52 and the drum screen 11 is stopped, the opened long hose opening / closing valve 79 and the like are closed, and the sludge concentrating vehicle 1 is moved to the disposal site.
