Comprehensive rural living sewage source separation, treatment and use system

Abstract

The invention discloses a comprehensive rural living sewage source separation, treatment and use system which comprises a biogas digester, a facultative anaerobic pond and a sand filtering pool, wherein the living sewage consists of black water and gray water; the black water is fed into the biogas digester for anaerobic treatment to generate biogas which can be recycled; the material discharged from the biogas digester can be recycled as an organic agriculture fertilizer for agriculture production; the gray water can be discharged into the facultative anaerobic pond and is subsequently degraded under the action of microorganisms and aquatic animals and plants; crops such as water hyacinths are planted in the facultative anaerobic pond, and the effluent of the facultative anaerobic pond is treated in the sand filtering pond, and is subsequently discharged out. With the combination of the biogas digester, the facultative anaerobic pond and the sand filtering pool, the rural living sewage can be treated, sewage treatment can be achieved, a function of environment protection can be also achieved, energy and products with economic values can be also obtained, and moreover, the comprehensive rural living sewage source separation, treatment and use system is simple to operate and maintain, and has wide application prospects in rural areas.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a system for comprehensive treatment and utilization of rural domestic sewage sources. Background technique [0002] With the rapid development of economy and society, environmental problems have become increasingly serious, among which water pollution is closely related to the survival and development of human society, directly affecting the further development of society. At present, most of the existing sewage treatment technologies are aimed at urban domestic sewage and industrial wastewater, while for rural domestic sewage, relatively few treatment technologies are involved. In addition, rural domestic sewage contains huge potential value, and energy and resources can be obtained from it. However, it is difficult to effectively use rural domestic sewage at present. Untreated discharge not only leads to environmental pollution problems, but also loses the possibility...

Problems solved by technology

At present, most of the existing sewage treatment technologies are aimed at urban domestic sewage and industrial wastewater; for rural domestic sewage, there are relatively few treatment technologies involved

In addition, rural domestic sewage contains huge potential value, and energy and resources can be obtained from it. However, it is difficult to effectively use rural domestic sewage at present. Untreated discharge not only leads to environmental pollution problems, but also loses the possibility of obtaining energy and resources from it.
