Abstract

The invention discloses a device for rapid treatment of village and town distributed sewage. The device comprises a two-section grille machine, wherein effluent of the grille machine is conducted to a one-stage surface layer turbulent flow screening and filtering device, the effluent of the one-stage surface layer turbulent flow screening and filtering device is conducted to an A2/O compound flow baffle plate soil infiltration system, the effluent of the A2/O compound flow baffle plate soil infiltration system is conducted to a two-stage surface layer turbulent flow screening and filtering device, and the effluent of the two-stage surface layer turbulent flow screening and filtering device is conducted to a cyclone desanding device. The invention also discloses a method for performing rapid treatment on the village and town distributed sewage by using the device.

Description

technical field [0001] The invention relates to a device for rapid treatment of collected and distributed sewage in villages and towns. [0002] The present invention also relates to a method for sewage treatment using the above-mentioned device. Background technique [0003] Current situation of water environment in villages and towns in my country my country is a large agricultural country, and the rural area accounts for 57.59% of the total land area of ​​the country. However, due to various reasons, the control of rural water pollution has not been paid enough attention. Pollution prevention and control investment is almost all invested in industry and cities, while rural environmental protection facilities are almost zero. In recent years, the situation of rural water environment has been deteriorating, and pollution accidents have occurred from time to time. The main reasons are: water environment pollution caused by pollutants discharged by township enterprises; non...
