Problems solved by technology

[0003] As time goes by, the underground sewage pipes will corrode and leak, which needs to be repaired. During the repair process, the section to be repaired needs to be temporarily closed, so that the sewage flowing in the underground sewage pipes cannot be discharged to the sewage treatment plant temporarily, which is easy Causes the accumulation of sewage and affects the environment, so there is still room for improvement

Abstract

The invention relates to the technical field of sewage treatment and provides a treatment method of urban domestic sewage for solving the problem that sewage is prone to being accumulated when an underground drainage pipe is maintained. According to the technical scheme, the treatment method comprises the steps that S1, the sewage is pumped from the upstream part of a blocked section of the underground drainage pipe; S2, the sewage is discharged into a settling tank to be precipitated, and meanwhile, a flocculant is sprayed; and S3, precipitated surface water in the settling tank is pumped into soil of green plants beside a road, wherein the flocculant is prepared from the following components in parts by mass: 100 parts of polyacrylamide, 15-20 parts of casein, 33-36 parts of methylcellulose, 3-5 parts of zinc oxide and 5-8 parts of activated carbon, and the settling tank is internally provided with an underwater ultraviolet lamp. The sewage is pumped out, treated and then dischargedinto the soil of the green plants beside the road, thus plant growth is not prone to being affected, through further filtration by soil and the plants, the treated sewage is discharged into the soil and then further purified, thus the sewage is not prone to being accumulated, the environment is not prone to being polluted, and environmental friendliness is realized.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a treatment method for urban domestic sewage. Background technique [0002] With the development of cities, there are more and more urban domestic sewage. It is necessary to collect urban domestic sewage through a planned urban sewage pipe network and transport it to sewage treatment plants for treatment to keep the city clean. [0003] As time goes by, the underground sewage pipes will corrode and leak, which needs to be repaired. During the repair process, the section to be repaired needs to be temporarily closed, so that the sewage flowing in the underground sewage pipes cannot be discharged to the sewage treatment plant temporarily, which is easy It leads to the accumulation of sewage and affects the environment, so there is still room for improvement. Contents of the invention [0004] In view of the deficiencies in the prior art, the object of the present invent...
