Urban sewage treatment equipment process
- Mar 15, 2018 -

The treatment effect of the urban sewage treatment equipment will be referred to as the enhanced first-level treatment in a certain degree between the primary and secondary treatment, and the primary and secondary treatment or the incomplete secondary treatment. There are two major categories of high-load biological treatment and chemical methods.

A secondary treatment system, in which the municipal sewage treatment equipment will have biological dephosphorization and denitrification functions to a certain extent, is generally referred to as a deep secondary treatment. In order to remove specific substances during the operation, it is set after the secondary treatment. The treatment system is a three-stage treatment, such as chemical phosphorus removal, flocculation filtration, activated carbon adsorption, and the like.

The primary treatment of the urban sewage treatment equipment effectively includes structures such as primary sedimentation basins, grit chambers, and grids, so that it can effectively remove coarse particles and suspended solids to a certain extent. The principle lies in effectively achieving its solid-liquid separation through its physical method and separating pollutants from sewage. This is a commonly used method of sewage treatment.

The necessary process section for the process flow of the urban sewage treatment equipment, the setting of the primary sedimentation tank, and the setting method must be carefully analyzed and considered according to the water quality characteristics and follow-up process, so as to ensure and improve the influent water quality of subsequent processes such as phosphorus and nitrogen removal.
