Problems solved by technology

[0003] For example, in some textile industries, a large amount of hair-like fabric fibers will be mixed in the wastewater discharged during the production process. During the sewage treatment process, the fabric fibers will be entangled in the treatment equipment or block the filter device in large quantities, resulting in a decline in the sewage treatment effect.

Abstract

The invention discloses a municipal sewage treatment system, and relates to the technical field of sewage treatment. The problems are solved that in the process of treating industrial sewage in the textile industry, cloth fiber in the sewage can wind a processing device or block a filter device to a large degree, and the sewage treatment effect is reduced. According to the technical scheme, the system includes a water storage pool, a pH regulating tank, an aeration tank and a settling pond arranged in sequence, the pH regulating tank is internally provided with a stirring device, and the stirring device includes a stirring shaft arranged in the pH regulating tank, a stirring rod connected with the peripheral side of the stirring shaft, and winding rods densely arranged on the stirring rodand used for fiber cloth winding. The content of the cloth fiber in sewage can be reduced, and thus the degradation of the sewage treatment effect is avoided.

Description

Technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a municipal sewage treatment system. Background technique [0002] With the acceleration of the process of urbanization and industrialization, the amount of municipal sewage produced has been increasing, and pollution has become increasingly serious, which has severely restricted the sustainable development of urban social and economic development. [0003] For example, in some textile industries, the wastewater discharged from the production process will be mixed with a large amount of fabric fibers like hair. In the sewage treatment process, the fabric fibers will be entangled in the treatment equipment or a large number of filter devices will be blocked, resulting in a decline in the sewage treatment effect. Summary of the invention [0004] The purpose of the present invention is to provide a municipal sewage treatment system, which can reduce the cloth fiber content in the ...
