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. Sewage treatment is widely applied to various fields such as buildings, agriculture, traffic, energy, petrifaction, environmental protection, urban landscape, medical treatment, catering and the like, and is increasingly used in daily life of common people.

Contaminants in wastewater generally exist in three forms: suspended (including floating), colloidal and dissolved states. The physical treatment of sewage is mainly the suspended matters and part of colloids which may block the impellers of water pumps and valves of pipelines and increase the load of subsequent treatment units, so the physical treatment of sewage is generally also called solid-liquid separation treatment of wastewater. The solid-liquid separation of waste water is mainly divided into two categories in principle: one is that the wastewater is limited to a certain extent, and suspended solids are removed by flowing in the water; another type is that the suspended solids are somewhat restricted and the waste water flows to discard the suspended solids. To which the grid belongs.
