First water inlet and outlet interfaces 12 and 13 are arranged on the two side walls of the upper chamber of the box 1, and second water inlet and outlet interfaces 102 and 103 are arranged on the two side walls of the box 1. When multiple mobile processing units are placed side by side, the first water inlet and outlet interfaces 12 and 13 can be connected to each other, and the second water inlet and outlet interfaces 102 and 103 can be connected to each other. In the box 1, the sewage collecting unit is connected to the second water inlet and outlet interfaces 102 and 103 of the lower chamber, and the sewage treatment unit is connected to the first water inlet and outlet interfaces 12 and 13 of the upper chamber.

[0035] Through the mobile processing unit, the worker can conveniently transport it to the location where the excrement or sewage is received. The sewage is sent from the second water inlet and outlet interfaces 102 of the lower chamber into the collecting barrel 2 for storage. After the sewage in the collecting barrel 2 is collected, multiple mobile processing units can be moved and placed side by side, so that the collecting barrels 2 of the multiple mobile processing units are connected end to end. Different sewage treatment units are arranged in the upper chambers of the multiple mobile processing units, and the collecting barrel 2 in the last mobile processing unit is connected to the sewage treatment unit. The collecting barrel 2 of the mobile processing unit is used to deposit impurities in the sewage, and then the sewage is pumped to the sewage treatment unit above. Through the different sewage treatment units arranged in the multiple mobile processing units, the sewage is subjected to aeration, chemical adsorption, filtration and physical adsorption. After the sewage is treated, it is discharged from the sewage collecting unit of the first mobile processing unit. The mobile processing unit realizes rapid treatment of excrement in outdoor mobile toilets and treatment of excrement by the mobile processing unit as a sewage treatment pool on site, thereby improving the efficiency of packaging treatment of excrement and sewage outdoors.

[0036] Referring to Figure 5Specifically, the sewage collection unit includes a collecting bucket 2 fixedly installed in the lower chamber, a water collecting pipe 21 connected to the second water inlet interface 102 of the lower chamber is provided in the box body 1, the other end of the water collecting pipe 21 extends into the collecting bucket 2 and extends to the lower half of the collecting bucket 2, a first suction assembly is provided in the collecting bucket 2, the first suction assembly is connected to the second water outlet interface 103 of the lower chamber, the first suction assembly is used to pump the sewage in the collecting bucket 2 from top to bottom to the second water outlet interface 103, the second water inlet interface 102 of the lower chamber is used to connect the external sewage source / the second water outlet interface 103 of the lower chamber of the adjacent box body 1, the bottom of the collecting bucket 2 is connected to a sewage pipe 22 extending out of the box body 1, and the sewage pipe 22 is also provided with a valve for opening and closing the sewage pipe 22, and the top of the collecting bucket 2 is also connected to a ventilation pipe 23, which passes through the partition 11 and out of the top of the box body 1 to balance the air pressure in the collecting bucket 2.

[0037] The suction assembly specifically includes a floating filter head and a suction pump 31. The floating filter head includes a floating head 32 whose upper portion can float on the water surface and a filter cartridge 33 connected to the bottom of the floating head 32. The filter head is provided with a connection port that communicates with the top of the filter cartridge 33. The floating head 32 is specifically made of PC plastic. The floating head 32 is hollow inside, allowing it to drive the filter cartridge 33 to float in the feces and sewage in the collection tube. Water filtration holes are provided around the filter cartridge 33. A telescopic tube 34 is connected to the bottom of the filter cartridge 33. The end of the telescopic tube 34 away from the filter cartridge 33 is connected to the water inlet end of the suction pump 31, and the water outlet end of the suction pump 31 is connected to the second water outlet interface 103. The telescopic tube 34 can be a corrugated tube.

The four sewage treatment units can be repeatedly arranged. According to the type and the pollution degree of the sewage to be treated, the three mobile treatment units can be flexibly selected. In an embodiment of the present application, when the sewage is pumped from the sewage collection unit to the sewage treatment unit, it sequentially passes through the aeration unit, the filtration unit and the physical adsorption unit. The static sewage is subjected to aeration treatment by the aeration unit, and the suspended and insoluble substances in the aeration-treated sewage are intercepted by the filtration unit. Finally, the foul odor and harmful substances in the sewage are deeply adsorbed by the physical adsorption unit and discharged.

[0049] In an embodiment of the present application, when the sewage is pumped from the sewage collection unit to the sewage treatment unit, it sequentially passes through the aeration unit, the chemical adsorption unit, the filtration unit and the physical adsorption unit.

When the skid-mounted fecal sludge treatment device is actually used, the sewage treatment unit can be first detached from the box body 1, and only the mobile treatment unit with the collecting barrel 2 is moved to the place where fecal sludge collection is needed for collection. After the collecting barrel 2 is full of fecal sludge, the staff moves the box body 1 and the internal collecting barrel 2 of the mobile treatment unit as a whole, sequentially connects the water inlet interface and the water outlet interface on the side wall of each mobile treatment unit box body 1, then installs the appropriate sewage treatment unit into the upper chamber of the box body 1, connects each sewage treatment unit with the first water inlet interface 12 and the first water outlet interface 13 of the upper chamber, and connects the second water outlet interface 103 of the last mobile treatment unit with the first water inlet interface 12 by using a connecting pipe.
