Sewage source processing system and processing method

Abstract

The invention relates to the technical field of sewage processing, more specifically to a sewage source processing system for processing life sewage and a processing method, wherein the sewage source processing system comprises sewage drainage main pipes, source sewage drainage branch pipes, shunting wells, a water treatment wetland and a digestion pool. The sewage processing method provided by the invention comprises the following steps of: respectively constructing sewage source processing systems at each settlement by the adoption of a distributed processing mode; arranging the shunting wells at entrance points of the sewage drainage main pipes, introducing sewage into the shunting wells through the source drainage branch pipes for the shunting of part of water body, purifying the shunted water body thorough the water treatment wetland, and condensing sewage which undergoes shunting of part of the water body into a slurry; and carrying out an anaerobe bio-fermentation treatment on the slurry to generate biogas. The sewage source processing system and method disclosed by the invention has advantages of no peculiar smell in the environment during the sewage processing process, nosecond environmental pollution, low investment and high processing efficiency. By the adoption of the system and the method, the environmental protection requirement on zero discharge can be achieved.

Description

Technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment system and a treatment method for treating domestic sewage. Background technique [0002] At present, the treatment of sewage generated by human activities has been developed to a centralized sewage treatment system in which the primary treatment of septic tanks in the community passes through the urban sewage drainage pipe network to the sewage treatment plant. After the treatment reaches the standard, it is discharged to the river. However, due to the huge investment in the construction of centralized sewage treatment system facilities, it not only caused heavy construction investment pressure on related enterprises, but its large-scale municipal construction also formed a heavy financial burden on the government, and due to the construction of centralized sewage treatment system facilities The huge financial pressure and the huge amount of engineering ha...

AI Technical Summary

Problems solved by technology

[0004] 2) The overflowing water of septic tanks and biogas digesters causes a large amount of heat loss and reduces the density of anaerobic biological flora, which affects the biotransformation efficiency of organic matter;

[0005] 3) Cannot effectively use green space resources for ecological circulation water treatment;

[0006] 4) The construction of the facility system of the centralized processing method is complex, with huge investment, basically no return for facility operation, high operation and maintenance costs, and an effective economic cycle system of benefits cannot be established;

[0007] 5) The facility construction of the centralized processing method requires concentrated and large one-time capital investment. In addition to the national policy-based financial investment above the prefecture and city level, local governments and enterprises in townships, streets, and towns do not have the financial investment capacity to establish a complete processing system;

[0008] 6) The urban sewage treatment plant occupies a large area, requires high equipment, and it is difficult for the effluent quality to meet the standard;

[0010] 8) The urban sewage treatment plant is far away from the urban area, and the long-distance sewage drainage not only increases the construction investment of the drainage pipe network, but also increases the difficulty of recycling fresh water resources after treatment
