City sewage treatment apparatus and method thereof

Abstract

The invention discloses a city sewage treatment apparatus. The city sewage treatment apparatus comprises a filtering casing and a biological treatment apparatus, the filtering casing comprises a fixedrack body, a fixed case and a filtering assembly, the filtering assembly is positioned in the fixed case, the filtering assembly comprises a filter cylinder, a filtering rotating hopper, and a rotating mechanism, a filter sieve is arranged in the filter cylinder, filter tank apertures are uniformly distributed at a side wall of the filtering rotating hopper, the bottom of the filtering rotating hopper is fixedly connected with the rotating mechanism, the biological treatment apparatus comprises a distributive pipe, a biological treatment pipe group, a water collecting pipe, and a support frame, and a water outlet hopper is arranged at the bottom of the water collecting pipe. A treatment method comprises the following steps: A) area division; B) sampling for detection; C) apparatus installation; and D) sewage processing. The city sewage treatment plant apparatus and the method have the advantages that the treatment method is ingenious and reasonable, and has regional and targeted treatment on riverway, targeted treatment can be carried out on pathogen types in the sewage in the different areas, and processing water quality of the sewage can be effectively increased.

Description

technical field [0001] The invention relates to an urban sewage treatment device and method. Background technique [0002] In the formation and development of cities, rivers, as important resources and environmental carriers, are related to urban survival, restrict urban development, and are important factors that affect urban style and beautify the urban environment. Urban rivers have various ecological functions such as water supply, green space, environmental protection, transportation, and cultural education. It shows irreplaceable significance in the construction of cities and the expansion of urban space development. With the acceleration of urbanization in our country, land development and utilization on both sides of the river have damaged the function of urban rivers, and a large amount of industrial and domestic sewage has been directly discharged into the river without treatment, causing river water pollution, water quality deterioration, and river ecological env...

AI Technical Summary

Problems solved by technology

With the acceleration of urbanization in my country, the development and utilization of land on both sides of the river has damaged the function of urban rivers, and a large amount of industrial and domestic sewage has been directly discharged into the river without treatment, causing river water pollution, water quality deterioration, and river ecological environment damage.

The existing sewage treatment devices are bulky, costly, and the actual operation is complicated, which is not convenient for later maintenance and cleaning

Moreover, the banks on both sides of the river are long, the pollution sources of different river sections are different, and the types of bacteria in the sewage are also different. The existing sewage treatment devices generally use the same device to treat the sewage, and there is no targeted treatment according to the pollution conditions of different river sections. Scientific treatment leads to unsatisfactory treatment of river sewage
