Abstract

The invention discloses a rural domestic sewage reutilization treatment device. The rural domestic sewage reutilization treatment device comprises a methane tank, a grating pretreatment unit, a buried aerobic tank, an aerobiont filter tower and a subsurface flow contructed wetland, wherein methane generated in the methane tank is subjected to denitrification and sulfate reduction under an anaerobic condition; the methane serves as a carbon source to intensify anaerobic biochemical treatment; the treatment efficiency can be improved by virtue of a warming function of the methane; and backflow is formed behind a tower-type biofilter, so that the denitrification percent is improved. The rural domestic sewage reutilization treatment device can be used for effectively removing organisms and efficiently removing nitrogen and phosphorus, occupies small floor area, is low in operation cost, can be adaptive to local conditions, and can reutilize wastes.

Description

technical field [0001] The invention relates to the field of environmental engineering, in particular to a device for treating rural domestic sewage as a resource. Background technique [0002] In recent years, with the development of my country's rural areas and the rapid improvement of rural people's living standards, the discharge of rural domestic sewage has continued to increase, and rural domestic sewage has become another serious pollution source next to urban sewage. At the same time, due to the scattered and wide-ranging pollution sources in rural areas, the small amount of sewage, and limited by natural conditions, rural domestic sewage is scattered and difficult to collect. It is difficult to lay sewage collection pipes on a large scale, making rural domestic sewage not included Large-scale centralized sewage plants conduct centralized treatment, and the harmless treatment rate of rural domestic sewage is very low. We can only find more suitable sewage treatment m...
