Efficient and energy-saving unpowered rural sewage treatment system

Abstract

The invention discloses an efficient and energy-saving unpowered rural sewage treatment system. The system comprises a device body and a cover body arranged on the device body; wherein the device bodyinternally comprises an anaerobic zone, an inner ring aerobic zone and an outer ring settling zone; the anaerobic zone is arranged at the bottom of the device body, is communicated with an external septic tank through a water inlet pipe and is communicated with an overflow pipe through a water outlet pipe, and a plurality of through holes are formed in the top of the overflow pipe; the inner ringaerobic zone comprises a first folded paper filter element, a second folded paper filter element, a first water pan, a third folded paper filter element, a fourth folded paper filter element and a second water pan, which are sequentially arranged below the overflow pipe; a plurality of water through holes are formed in the first water pan; the inner ring aerobic zone is communicated with the outer ring settling zone through a first water outlet; a second water outlet is formed in the outer ring settling zone.

Description

technical field [0001] The invention belongs to the technical field of rural sewage treatment, and in particular relates to a high-efficiency and energy-saving non-powered rural sewage treatment system. Background technique [0002] At present, the rural economy is developing rapidly, and the living standards of farmers have been greatly improved. However, the construction of the rural environment is not in sync with economic development, and the problem of water pollution is particularly serious. Untreated domestic sewage is discharged randomly, causing the water quality of ditches and ponds to turn black and smelly, and mosquitoes to breed, affecting the living environment in rural areas and threatening the health of residents. At the same time, it will cause pollution of drinking water sources and eutrophication of lakes and reservoirs . [0003] Due to limited economic conditions and lack of awareness of environmental protection, most of the rural areas in my country co...
