A municipal sewage oxidation treatment method

Abstract

The invention belongs to the technical field of sewage treatment, and particularly relates to a municipal sewage oxidation treatment method. A municipal sewage oxidation treatment device utilized in the method includes a main body, a pushing plate, a telescopic air cylinder, a guide pipe, a gas feeding disc, a stirring and mixing unit, a holding chamber and a sediment chamber. The pushing plate isat the upper end of the main body and is driven by the telescopic air cylinder. The inner wall of the guide pipe is spiral. The gas feeding disc is inlaid in the inner wall of the main body and is connected to an external ozone feeding pipe. The stirring and mixing unit is used for introducing ozone fed through the gas feeding disc and a sedimentation agent into sewage and fully mixing and stirring the mixture. The holding chamber is below the stirring and mixing unit to separate the sewage into supernatant liquid and sedimented particles. The sediment chamber is used for receiving particlessedimented in the holding chamber. Municipal sewage is treated in a manner with low energy consumption, is fully purified and disinfected by the device, and is allowed to be easily sedimented, and thesewage treatment efficiency is increased.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to an urban sewage oxidation treatment method. Background technique [0002] With the development of society, more and more artificially synthesized compounds have entered the water body, resulting in some highly stable and difficult-to-oxidize organic compounds in the water body, which have caused serious damage to the water environment. The economical and effective removal of such refractory organic pollutants in water has become a hot spot in research and engineering applications in the field of water treatment. In recent years, the advanced oxidation technology researched and developed using ozone as an oxidant can oxidize and decompose toxic and refractory organic pollutants in water, and has received more and more attention.

[0003] In recent years, my country's environmental workers have done a lot of work in sewage treatment, regeneration and recycling. Some sewage treatment plants use enzymes to treat sewage, and then produce regenerated water through filtration and ozone disinfection. However, ozone is produced with an ozone generator, and the manufacturing cost Large, when ozone oxidation is used to treat sewage, the mixing degree of ozone and sewage is not high, so that the effect of ozone treatment of sewage is not obvious; at the same time, in the process of sewage treatment, it needs to consume a lot of energy to support the operation of equipment. consumes a lot
