Rural domestic sewage composite ecological purification system

Abstract

The invention discloses a rural domestic sewage composite ecological purification system, which comprises a water inlet well, a primary sedimentation tank and an aeration regulating tank, wherein a grid is obliquely arranged in the primary sedimentation tank, the water outlet of the aeration regulating tank is respectively connected with an artificial subsurface flow wetland and buried integratedsewage treatment equipment in parallel, the sludge outlets of the artificial subsurface flow wetland and the buried integrated sewage treatment equipment are connected with a sludge tank, the water outlet of the buried integrated sewage treatment equipment is communicated with an integrated equipment produced water treatment system, and the water outlet of the integrated equipment produced water treatment system and the water outlet of the artificial subsurface flow wetland are respectively communicated with big pits. According to the invention, a stable purification effect can be exerted throughout the year, the problem that existing rural constructed wetlands do not reach the standard in winter treatment or are difficult to operate and manage is solved, the system can be communicated with a matched sewage collection pipe network in a village, the problem that rural domestic sewage discharge does not reach the standard is solved, treated water reaches the standard and is discharged into nearby drainage ditches or used for farmland irrigation, water resources are fully utilized, and meanwhile ecological and ecological benefits are remarkable.

Description

technical field [0001] The invention relates to the technical field of domestic sewage treatment, and more specifically relates to a compound ecological purification system for rural domestic sewage. Background technique [0002] With the development of rural areas, the discharge of domestic sewage in rural areas is increasing day by day. Domestic sewage in rural areas mainly comes from toilet flushing water, kitchen washing water, washing machine drainage, shower drainage and other drainage. At present, most of the rural domestic sewage is directly discharged into the environment, causing great pollution to the environment and producing a foul smell. Therefore, the treatment of rural domestic sewage is very important. [0003] At present, domestic sewage treatment in rural areas is an important and difficult project. The reasons are as follows: most rural areas have not set up sewage treatment stations and household sewage pipes, and the newly built sewage pipes and sewage...
