[0002] Rural sewage primarily originates from the daily lives of rural residents and agricultural production activities, including household wastewater, toilet wastewater, kitchen wastewater, aquaculture wastewater, and agricultural production wastewater. Currently, only a few villages have the conditions to establish centralized sewage treatment facilities, and sewage within the village is treated centrally. However, due to economic and geographical reasons, most villages are unable to build centralized sewage treatment facilities, and each household can only build simple sewage treatment facilities on its own.

[0003] In the existing technology, self-built sewage treatment facilities generally include multiple tanks, each of which carries out different sewage treatment processes. The tanks are equipped with electrical process equipment including phosphorus removal devices and aeration devices. These electrical process equipment are often independently controlled and require manual operation at regular intervals. The degree of automation is low. Pipelines are set between the tanks and sewage is transferred by pumping. A large number of pumps are set and require manual operation, which further makes the operation complicated and cumbersome. The large number of pumps leads to high costs and loud operating noise. Utility Model Content

The solenoid valve 6, the air pump 1 and the electrical process equipment and control system of the sewage treatment facility are electrically connected.

[0041] Sewage is transported between multiple tanks of the sewage treatment facility by air lift. The air lift includes a lifting pipe and an outlet pipe that are interconnected at the top. The lifting pipe is connected to the tank that outputs sewage, and the outlet pipe is connected to the tank that receives sewage. An air inlet pipe is provided in the lifting pipe, and the air inlet pipe passes through the cabinet 100 and is connected to the interface pipe 5. Some tanks are provided with aeration devices, and the air supply pipe that provides air source for the aeration device also passes through the cabinet 100 and is connected to the interface pipe 5. The cabinet 100 is correspondingly provided with pipe holes for the air inlet pipe and the air supply pipe to pass through, as well as wire holes for the lines to pass through.

[0042] The utility model centrally controls the electrical process equipment of the sewage treatment facility, and can automatically control the sewage treatment facility through the control system, thereby improving the degree of automation of sewage treatment. The cabinet 100 is small in size and occupies little space. The enclosure 103 and the drainage hole 104 arranged on the top prevent rainwater from seeping into the cabinet door 101 from the top and entering the cabinet 100. The air pump 1 controlled by the control system is set as not only the air source of the aeration device, but also the air source for air lift transportation of sewage between tank bodies, so that one air pump 1 can be used for sewage transportation between multiple tank bodies. Compared with the traditional method of pumping with multiple pumps, not only the cost is greatly reduced, the operating noise is reduced, and the air pump 1 is placed in the cabinet 100 for easy repair and maintenance at any time.
