Abstract
The invention belongs to the technical field of water treatment, and particularly relates to a rural sewage collection and treatment system. According to the system, rainwater and domestic sewage are collected through the side canal, the sewage intercepting pipe is arranged to be communicated with the sewage draining exit in the side canal, the domestic sewage and initial rainwater enter the sewage intercepting pipe through the sewage draining exit, and the situation that the domestic sewage and the initial rainwater with the large sewage content enter a river channel to pollute a receiving water body is avoided. A sewage treatment device is arranged to treat the sewage intercepted by the sewage interception pipe, anaerobic microorganisms are utilized to digest and treat organic matters, anaerobic and aerobic alternate treatment is utilized to remove COD (Chemical Oxygen Demand), BOD5 (Biochemical Oxygen Demand) and most of nitrogen pollutants, and phosphorus and residual nitrogen are used as nutrients to be absorbed by plants in the constructed wetland; and the effluent meets the requirements of the first-grade discharge B standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB1891802002). The sewage collection and treatment system is simple in process, low in capital construction and operation and maintenance cost, convenient to manage and capable of meeting the collection and treatment requirements of rural sewage.
Description
technical field [0001] The invention belongs to the technical field of water treatment, and more specifically relates to a rural sewage collection and treatment system. Background technique [0002] The quality of the water environment is one of the most important factors affecting the living comfort of residents, and water treatment in rural areas has always been a problem in the field of water treatment. The stench soared into the sky, seriously affecting the normal life of the surrounding residents. [0003] For the construction of rural sewage collection and treatment system, on the one hand, from the perspective of drainage, the amount of sewage in rural areas is small, the discharge is scattered, and the collection and treatment are difficult, so the design experience of urban drainage system is difficult to apply to rural areas; From the perspective of water treatment, rural areas have relatively poor economic foundations, lack of operation and management funds, and ...
