Background

In the prior art, sewage treatment is a process for purifying sewage to meet the water quality requirement of being discharged into a certain water body or reused. The sewage treatment is widely applied to various fields of buildings, agriculture, traffic, energy sources, petrifaction, environmental protection, urban landscapes, medical treatment, catering and the like, and the sewage treatment is increasingly carried into the daily life of common people.

Contaminants in sewage generally exist in three forms: suspended (including floating), colloidal and dissolved. The physical treatment of sewage is mainly suspended matters and part of colloid which can block the impeller and the pipeline valve of the water pump and increase the load of the subsequent treatment unit, so that the physical treatment of sewage is also commonly called solid-liquid separation treatment of wastewater. In principle, the solid-liquid separation of wastewater is mainly divided into two main categories: one type is that wastewater is limited to a certain extent, and suspended solids flow in the water to be removed; the other type is that suspended solids are limited to a certain extent, wastewater flows to discard the suspended solids, and the grid belongs to the latter. The grid is the most main auxiliary equipment in the sewage pump station, and the grid is generally composed of a group of parallel grid bars and is obliquely arranged at the inlet of a water collecting tank of the pump station.

The prior grid is made of carbon steel, hot galvanizing is carried out on the surface, and the oxidation prevention effect can be achieved, but when a certain part of the grid is damaged by external corrosion or artificial reasons, the whole grid needs to be replaced when serious, and the maintenance cost is increased.
