Description

Technical Field

[0001] The invention relates to the technical field of rural sewage treatment equipment, and in particular to a multifunctional cabinet for a rural sewage treatment station and a use method thereof. Background Art

[0002] Rural sewage treatment stations are important facilities for rural domestic sewage treatment. Domestic sewage from farmers is collected through the pipe network and enters the sewage treatment facility. Through the facultative oxygen and aerobic action of microorganisms, most of the pollutants in the sewage are removed. After precipitation, it enters the ecological treatment system to ensure that the effluent meets the discharge standards. The process of rural sewage treatment stations includes: sewage collection pipe network -> regulating tank -> flow meter -> integrated purification tank -> wetland -> discharge into the nearest water body. The equipment of rural sewage treatment stations mainly includes submersible sewage pumps, flow meters, aeration pumps and station electric control cabinets in the regulating tank. When building a rural sewage treatment station, it is necessary to build an electric control cabinet, instrument protection box, equipment foundation of the aeration pump and flow meter well, and lay power and instrument cables from the electric control cabinet to each equipment. The amount of civil engineering is large and the installation and commissioning work is cumbersome. In addition, the equipment is exposed to the outdoor environment for a long time, which greatly shortens its service life. The vibration and noise pollution generated during the operation of the equipment affect the normal life of surrounding residents. At the same time, the rural sewage treatment station is located in a low-lying area, and the aeration pump and electric control cabinet have the potential safety hazards of being submerged by rainwater.
