Problems solved by technology

Moreover, there are few decentralized governance projects used in rural areas, and many treatment technologies are only in the research and demonstration stages of pilot and small tests
At present, there is still a big difficulty in the treatment of rural domestic sewage, that is, the infrastructure investment and operating costs are relatively large, and the rural economy and technical strength are difficult to meet the technical requirements of conventional urban domestic sewage treatment plants.

Abstract

The invention discloses a reinforced aeration artificial wetland for treating domestic sewage. The reinforced aeration artificial wetland comprises a grid sedimentation tank, a hydrolysis acidification tank, a contact oxidation tank, a secondary sedimentation tank, an artificial wetland tank and an oxidation stabilization pond; and the grid sedimentation tank, the hydrolytic acidification tank, the contact oxidation tank, the secondary sedimentation tank, the artificial wetland tank and the oxidation stabilization pond are sequentially arranged in a communication mode. The reinforced aerationartificial wetland for treating domestic sewage has good economic benefits and ecological benefits, and has the advantages of low investment, low operation cost and good water quality of outgoing water.

Description

technical field [0001] The invention relates to an enhanced aeration artificial wetland for treating domestic sewage. Background technique [0002] At present, more than 90% of the villages in our country do not have drainage channels and sewage treatment systems, and the random discharge of domestic sewage seriously affects the environment and endangers people's physical and mental health. In addition to the low treatment rate of rural sewage, another characteristic of rural sewage is the small and scattered intermittent discharge, especially in southern villages where the settlements are more scattered. The domestic treatment of domestic sewage in rural areas has only been paid attention to after the pollution of rivers and lakes has intensified. Moreover, there are few decentralized governance projects used in rural areas, and many treatment technologies are only in the research and demonstration stages of pilot and small tests. At present, there is still a big difficul...
