Abstract

The invention belongs to technical field of sludge treatment, and discloses a sludge treatment method. The sludge treatment method comprises the following steps: A, introducing sewage into a standingtank, standing for laying, and enabling high-density substances to be sunken to the water bottom and low-density substances to float on the water surface; B, introducing intermediate-layer sewage in the standing tank into a sedimentation tank, and carrying out agglomeration and settlement of suspended particles in the sewage by a flocculant; C, introducing upper-layer sewage in the sedimentation tank into constructed wetland, and degrading harmful substances in the sewage through an artificially constructed ecosystem in the constructed wetland; D, introducing the sewage in the constructed wetland to a water collecting tank through a solar distillation unit. In the invention, after the sewage passes through the standing tank and the sedimentation tank, the construction and operation cost ofthe sewage treatment is reduced by setting the constructed wetland, and the solar distillation unit is arranged to save an external energy source, therefore, water sources treated by the constructedwetland are further purified by distillation and collected in the water collecting tank, and the sludge treatment method is simple, convenient, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment method. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. [0003] With the gradual improvement of people's water quality requirements in industrial production and daily life, sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering and other fields, and more and more Into the daily life of ordinary people. [0004] However, the existing sewage treatment process is complex, inefficient, and costly, and has low practicability for some low-pollution industrial sewage and domestic sewage. Contents of the invention [0005] The object of the present invention is to provide a sewage treatment method for treating low-pollutio...
