Domestic sewage bioreaction treatment and recycling system

Abstract

The invention discloses a domestic sewage bioreaction treatment and recycling system which belongs to the technical field of sewage disposal. The system is composed of a collecting pipe network, an inlet well, a sedimentation tank, a regulating tank, an anaerobe filter tank, an aerobe discharge tank, a clear water tank, a drain tank, an equipment room, lifting pumps, a blower, a biological chemical feeder and pipelines, wherein the collecting pipe network is connected to the inlet well; the inlet well is provided with a water inlet; the water inlet is connected with the sedimentation tank through the pipeline; after sedimentating in the sedimentation tank, sewage enters the regulation tank through the pipelines; the two lifting pumps are arranged in the regulation tank and connected with the anaerobe filter tank through the pipelines; the sewage enters the aerobe discharge tank through the pipeline to be processed in a biological treatment way, and enters the clear water tank; water in the clean water tank, which is processed in a biochemical treatment mode, enters the ambient river course via the drain tank; the outlet of the blower is connected with the aerobe discharge tank; the blower is arranged in the equipment room; and the biological chemical feeder and a control cabinet are arranged in the equipment room. The invention has the advantages of simple treatment process, stable operation, simple management, low energy consumption, convenient maintenance and low cost.

Description

[technical field] [0001] The invention relates to a technical device for sewage treatment, in particular to a biological reaction treatment recycling system for domestic sewage. [Background technique] [0002] With the increase of population, the acceleration of urbanization and the rapid development of society, the discharge of domestic sewage is increasing, the damage of domestic sewage discharge to the environment and the resulting shortage of water resources have become a serious obstacle to economic development and Obstacles to the improvement of people's quality of life, for this reason people have been committed to finding effective ways to recycle sewage, and through the formulation of various international conventions and discharge standards to limit and improve the discharge requirements of domestic sewage. [0003] At present, in rural areas, domestic sewage is mainly treated through soil infiltration. Although this method is simple, it seriously pollutes the surr...

Problems solved by technology

[0003] At present, in rural areas, domestic sewage is mainly treated through soil infiltration. Although this method is simple, it seriously pollutes the surrounding groundwater. Some rural areas also have sewage purification and discharge systems, but due to unreasonable and scientific design, the construction is difficult. The lack of norms and standards still fails to meet the requirements of harmless discharge; it not only pollutes the environment, but also pollutes groundwater, which seriously affects people's health. The discharge treatment has reached the point of urgency
