Problems solved by technology

[0002] At present, the distribution of rural living and residential areas is uneven, and the domestic sewage of most villages and towns cannot be incorporated into the urban sewage treatment system due to various reasons such as geography.
Most of the domestic sewage of village and town residents is directly discharged into rivers or used for agricultural irrigation without treatment, which seriously affects the rural environment, pollutes farmland soil, groundwater, etc., and threatens the safety of agricultural products.

Abstract

The invention relates to an integrated rural sewage treatment plant. The integrated rural sewage treatment plant is characterized by comprising a sewage collecting pool, a biological treatment system and a sludge tank. The sewage collecting pool is communicating with a biological treatment system through a conveying water pump; the biological treatment system comprises an anoxic pond, an anaerobic pond, an aerobic pond, a secondary sedimentation tank, a disinfection tank and a sand filtering system that are arranged from left to right and communicating with each other; the sludge tank is arranged aside the anoxic pond and the anaerobic pond and connected with the secondary sedimentation tank through a gas stripping device. The invention has beneficial effect that collected rural household sewage is treated by the integrated rural sewage treatment plant, and outlet water reaches grade 1 A discharge standard specified in GB 18918-2002 Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant. The integrated rural sewage treatment plant has advantages of stable performance, good treatment effect, small investment, small land occupation, simple operation, convenient management, long usage life and convenience for maintenance, etc., and is a whole set treatment plant designed specially according to water quality characteristics of rural household sewage.

Description

technical field [0001] The invention belongs to a sewage treatment device, in particular to an integrated rural sewage treatment device. Background technique [0002] At present, the distribution of rural living and residential areas is uneven, and the domestic sewage of most villages and towns cannot be incorporated into the urban sewage treatment system due to various reasons such as geography. Most of the domestic sewage of village and town residents is directly discharged into rivers or used for agricultural irrigation without treatment, which seriously affects the rural environment, pollutes farmland soil, groundwater, etc., and threatens the safety of agricultural products. Contents of the invention [0003] The present invention aims to overcome the deficiencies in the prior art, and provides an integrated rural sewage treatment device, which integrates the removal of BOD5, COD, TN, NH3-N, TP, and TSS, and is specially designed according to the water quality charact...
