Background Art

Agricultural sewage refers to sewage or liquid substances discharged during the process of crop cultivation, livestock breeding, agricultural product processing, etc., which affects human health and environmental quality. Usually, since agricultural sewage is more complicated to treat, the filter is very easy to be blocked, and needs to be cleaned frequently, which is costly, most people choose to discharge it directly into nearby rivers and canals. Some people only filter agricultural sewage roughly before discharging it directly, but this practice greatly affects the surrounding environment. In the long run, it will also pollute groundwater sources and pollute the nearby drinking water environment.

For example, Chinese patent publication number: CN212662867U is an agricultural sewage treatment equipment, which includes a treatment equipment body and a filter box located on one side of the treatment equipment body, a water inlet pipe is installed on one side of the filter box, one end of the water outlet pipe is installed on the other side of the filter box, and the other end of the water outlet pipe is fixedly installed on the treatment equipment body, connecting seats are fixedly installed on the side walls of the filter box, and the same filter net is placed on multiple connecting seats, a sealing seat is sealed in the filter box, one end of multiple vertical rods is fixed on the bottom of the sealing seat, and the other end of the vertical rods is fixedly installed on the filter net, a fixing seat is fixedly installed on the top of the sealing seat, and the fixing seat extends to the top of the filter box.
