Technical Field

The application relates to the field of sewage treatment technology, in particular to a municipal sewage treatment device.

Background

Sewage treatment refers to a process of purifying sewage to meet the water quality requirement for draining a certain water body or reusing the sewage. A large amount of sewage can be produced in daily municipal work, and the sewage is required to be treated, and the general sewage treatment is to carry out chemical reaction by adding a sewage treatment agent into a sewage tank, so that harmful substances in the sewage are purified to reach the sewage discharge standard.

The municipal sewage treatment standard in China is divided into three levels, namely primary treatment, secondary treatment and tertiary treatment. The first treatment is to remove suspended solid matters in the sewage by physical methods such as precipitation, flotation, filtration and the like, or to preliminarily purify strong acid, strong alkali and over-concentrated toxic substances in the sewage by chemical methods such as agglomeration, oxidation, neutralization and the like, so as to provide proper water quality conditions for the second treatment. The secondary treatment is based on the primary treatment and usually utilizes biochemical action to further treat the sewage. The tertiary treatment is also called deep treatment. On the basis of the secondary treatment, the tertiary treatment adopts corresponding treatment methods such as coagulation and precipitation, activated carbon filtration, reverse osmosis, ion exchange, electrodialysis and the like according to the quality of inlet water.
