Abstract
Description
Technical Field
[0001] This utility model relates to the field of sewage treatment technology, and in particular to an integrated sewage treatment device for rural areas. Background Technology
[0002] Wastewater refers to polluted wastewater from domestic and industrial processes. Its sources are wide-ranging, including domestic sewage such as kitchen wastewater and toilet wastewater, which contains a large amount of organic matter, microorganisms, and nitrogen and phosphorus nutrients; industrial wastewater, which varies greatly in nature depending on the industrial production process. For example, chemical wastewater contains heavy metals and toxic and harmful substances, while dyeing and printing wastewater is dark in color and contains a large amount of dyes and auxiliaries; agricultural wastewater mainly comes from farmland irrigation drainage, carrying fertilizers, pesticides, and silt from the soil. If wastewater is discharged directly without proper treatment, it will cause serious damage to the aquatic ecosystem, leading to water quality deterioration, mass death of aquatic organisms, soil pollution, and affecting crop growth. It can even threaten human health through the food chain and cause various diseases.
[0003] A search revealed Chinese Patent Publication No. CN111807648B, which discloses an integrated sewage treatment device suitable for rural sewage. The device includes an inlet pipe, an anaerobic biological treatment unit, an aerobic tank, a sludge-water separation tank, a sludge storage tank, a coagulation tank, a reaction tank, a sedimentation tank, a disinfection tank, and an outlet pipe. Along the sewage flow direction, the inlet pipe, anaerobic biological treatment unit, aerobic tank, and sludge-water separation tank are connected in series. The lower sludge zone of the sludge-water separation tank is connected to the sludge storage tank, and the upper water zone of the sludge-water separation tank is connected to the coagulation tank. The coagulation tank, reaction tank, sedimentation tank, and disinfection tank are connected in series, and the disinfection tank is connected to the outlet pipe. Sewage treated by this device can ensure that the effluent quality meets the Class A discharge standard of the "Discharge Standard of Pollutants for Urban Sewage Treatment Plants" (GB18918-2002).
