Comprehensive treatment system for organic garbage and domestic sewage and comprehensive treatment method therefor

Abstract

The invention discloses a comprehensive treatment system for organic garbage and domestic sewage and a comprehensive treatment method therefor. The comprehensive treatment system comprises an organic garbage treatment device on the ground, a sewage purification device under the ground and a tail water land utilization unit and is characterized in that at least one organic garbage reaction tank isarranged at the lower part of the organic garbage treatment device; a sewage shower pipe is arranged at the upper part of the organic garbage reaction tank; an overflow pipe is arranged at the lower part of the organic garbage reaction tank and is communicated with the sewage purification device; the sewage purification device is provided with a sewage inlet; and a tail water outlet connected with a perforated pipe arranged at the tail water land utilization unit and a backflow device connected with the sewage shower pipe are arranged at the bottom of the sewage purification device. The method mainly comprises the following steps of the treatment for the organic garbage, the purification treatment for the sewage and the utilization of the tail water land and has the advantages of simplifying the operation procedure, reducing the investment on facilities, lowering the running cost, improving the purification efficiency and the utilization efficiency of the pollutants in the organic garbage and the domestic sewage and realizing the aim of reusing the resources of water and fertilizer in the organic garbage and the domestic sewage.

Description

technical field [0001] The invention relates to a comprehensive treatment system and method for organic garbage and domestic sewage, in particular to a comprehensive treatment system and method for organic garbage and domestic sewage suitable for rural residential areas and tourism service industries. Background technique [0002] With the sudden increase in the number of recreational facilities and tourists in scenic spots, the rapid development of catering services such as resorts and farmhouses, the amount of domestic garbage and sewage has increased significantly, and the pollution of rural residential areas and tourism service industries in urban water source protection areas has become increasingly serious. , Bringing huge pressure on the ecological environment of urban water source protection areas, leading to a decline in the quality of urban drinking water sources and affecting the health and quality of life of urban residents. [0003] The existing treatment of org...

AI Technical Summary

Problems solved by technology

[0004] However, due to the fact that the living sources of pollutants in rural residential areas and tourism service industries have many points and areas, and small quantities and scattered characteristics, it is difficult to build pipe networks and collect sewage, and the investment cost of sewage treatment per unit is large, and the investment in tail water irrigation is large. The utilization has not achieved actual results; due to the large content of organic waste in the existing waste collection and treatment mode, there are problems such as heavy transportation and transit workload and high operating costs; since organic waste and domestic sewage are treated with different treatment facilities and different methods Disposal mode, inconvenient management and maintenance, the problem of environmental pollution in rural areas and scenic spots has not been fundamentally solved, and the water and fertilizer resources in organic waste and domestic sewage have not been fully utilized
