``Part of Eve is connected with a transparent tube so that the properties of the liquid passing through it can be visually observed.

Next, the mode of operation of the septic tank management vehicle of the present invention constructed as described above will be explained. When the septic tank management vehicle of the present invention is running, all switching cocks are in the closed state. When it arrives, remove the suction and drainage hose 3 from the hose reel G for suction and drainage hose
2, insert the tip into the septic tank M, and remove the septic tank y.
The sludge water inside is sucked into the sludge tank C, that is, the three-way switching cock.

Open 12 and switch the four-way switching trick quest.

While operating the vacuum pump ■, the two-way switching cock 28.
80, the air in the sludge tank C is released into the atmosphere through the pipe 3.11, and as the pressure in the sludge tank 0 is reduced, the Sludge water from the septic tank M is suctioned into the sludge tank 0 through the drainage hose 32. When the above-mentioned suction and accommodation operation into the sludge tank C is completed, the three-way switching cocks 1b and 19 are opened to switch off the flocculant liquid tank M. Measure a predetermined amount of flocculant liquid into the intermediate tank, and when the predetermined amount of flocculant liquid has flowed into the intermediate tank, close the three-way switching cock 1B while opening the two-way switching cock 20 and turn the intermediate tank. The flocculant liquid in the tank is stored in the sludge tank 0. This storage may be carried out by suction using the reduced pressure state of the sludge tank O, or it may be carried out by gravity flow. If an aqueous solution is used for 0, 1 to 039 of a thionic polyacrylamide polymer flocculant in the flocculant solution to the sludge tank C, the volume should be 2.1 to 4 volumes relative to the sludge water in the sludge tank 0. It is preferable that the sludge water o in the sludge tank 0
1 to \Hiki IX are determined by the liquid volume scale provided on the sludge water IIC as described above.Also, the reaction tank L
C is for reacting the flocculant liquid and sludge water and monitoring the reaction.
After storing the flocculant liquid from the flocculant liquid tank A in the flocculant liquid tank A, the flocculant liquid and the sludge water are stirred and mixed using the stirring mechanism 0' to flocculate the solid content in the sludge water into flocs. This can also be carried out by leaving the sludge tank C under reduced pressure; in this case, the suction and drainage hose 32. The flocculant liquid and sludge water in the sludge tank C are stirred and mixed by the air sucked into the sludge tank C through the pipes 31 and 26.

Note that the stirring and mixing by the stirring mechanism C' and the stirring and mixing by air may be used together, or either one of them may be used.

The sludge water that has undergone the primary treatment as described above in the sludge tank C is then transferred to a filtration device where it is separated into collected sludge and filtered water.The flocculated sludge is stored in the sludge tank E, while the filtrated water is Accommodates p-water tank BK. This switching operation is carried out by switching the four-way switching cock I after completing the agitation and mixing in the sludge tank 0 and closing the nitrogen switching cocks 30 and 2.
After bringing the sludge tank O to atmospheric pressure via This can be done by driving the rotary screen cylinder 41. In other words, if K is performed in this way, pressurized air is sent from the vacuum pump H through the pipe 11 as shown by the arrow to bring the sludge tank C into a pressurized state. Therefore, the primary treated sludge water in the sludge tank B can be pumped from one end of the rotary screen pipe 41 via the eve 33 to the rotary screen pipe 41 in the transit dn. The primary treated sludge water is separated into filtrate water and flocculated sludge as the rotary screen tube 41 rotates, and the filtrated water flows down or drips from the screen surface into the filtrated water receiving tank 40 while flocculating. The sludge falls from the other end 41' and is accommodated in the sludge tank 1 from the sludge intake section 45. The temporary water that has flowed down or dripped into the filtered water receiving tank 40 is then transferred to the vacuum pump (2). Air is sucked through the pipe 3 as shown by the arrow, and the filtered water tank B is kept under reduced pressure. pipe 36t
- through which the perfused water is sucked into and contained in B as shown by the arrow. In this case, the flocculant does not substantially remain in the filtrate water, and there is no risk of the seed sludge in the filtrate water dying, so if this is used as water filling, the septic tank M will function normally. do. In addition, since the horizontal rotary screen tube 41 is adjustable in rotation speed as described above, it is possible to adjust the rotation speed by slowing down the rotation speed or by adjusting the rotation speed of the horizontal rotary screen tube 41.
By setting 1 to the mid-autumn condition as shown in the drawing, the conveyance speed of the flocculated sludge can be slowed down and the separation effect can be enhanced,
In particular, by making the rotary screen tube 41 freely tiltable as in the embodiment, when the septic tank management vehicle is stopped on a slope (lower 9 slopes) for work, the rotary screen tube 41 is fixed instead of being tiltable. The separation effect can be further enhanced compared to the conventional method. In addition, in the above-mentioned filtration device, since the outer casing 44 is transparent, it is possible to observe the clogging state of the rotary screen tube 41, and since the outer casing 44 surrounds the rotary screen tube 41, it is possible to observe the clogging state of the rotary screen tube 41. It is possible to prevent scattering, and furthermore, since the tube 36 is transparent, it is possible to observe the properties of the filtrate passing through it. After closing the cocks 84, 85, 87, and 13, switching the four-way switching cock, and opening the nitride switching cock 12 to bring the sludge tank C and the filtration tank B to atmospheric pressure, the filtered water in the filtration tank B is To perform this operation, switch the four-way switching valve and leave only the nitrogen switching cocks 12, 5, 27, and 80 in the open state. Air is forced into the filtration tank B through 7°8.3, and the filtration tank BO is pressurized by this pressure feeding.

The temporary water in the filtration tank B is pumped into the septic tank M via the pipes 2I, 31 and the suction/drainage hose s2.

After the above operations are completed, return the four-way switch cock, etc. to the above-mentioned running state, and drive to the first Joihi-hinoki.
The above-described operation is repeated for many cypresses, and when the sludge tank l is filled with flocculated sludge, the flocculated sludge can be transported to a sludge water treatment plant. In this way, only flocculated sludge needs to be treated at the sludge water treatment plant, which prevents sludge water from a septic tank with a low sludge concentration from being input into a sludge water treatment plant built for raw human waste. The fact that the ability was overflowing can be resolved. In addition, three-way switching cock 4
By opening 8, high-pressure clean water can be jetted from the cleaning nozzle 42 to clean the rotary screen cylinder 41, and by opening the three-way switching cock 51,
High-pressure clean water can be jetted out from the tip of the cleaning hose 50 to clean various areas.

In the above embodiment, the filter water tank B, the sludge tank 0, and the filtration device are mounted in this order from the front to the rear in the center of the septic tank management vehicle, and the Ap1 flocculant liquid tank A is mounted in the front left side of the vehicle body. In addition, the fresh water tank y is installed at the rear of the right side of the vehicle body, the sludge tank E is installed below the filtration device, and the hose reel Gf for the suction and drainage hose is installed above the filtered water tank B. By arranging relatively large components in the tank, it is possible to use a small vehicle with a loading weight of less than 4 as a septic tank management vehicle.

As described above, the septic tank management vehicle of the present invention can improve the treatment efficiency of sludge water by stirring and mixing the flocculant liquid into the sludge water to be treated according to its concentration to form flocs. Instead of relying on frequent back and forth work between the septic tank and the sludge water treatment plant as in the past, the septic tank can be treated at the location where the septic tank is located, and the septic tank can be filled with filtered water at the same time. In addition to making septic tank management and sludge water treatment work easier and faster, such as allowing the septic tank to function normally, it also prevents the sludge water treatment plant from overflowing. ! Moreover, it has great effects such as being able to prevent sludge from a thin septic tank from being mixed in as it is in a sludge water treatment plant built for the treatment of thick sludge water.
