Description

Domestic sludge filter box

technical field

The invention relates to a filter box, in particular to a domestic sludge filter box.

Background technique

In chemical enterprises, after entering the biochemical reaction in the biochemical tank, the domestic sewage generated by each device needs to be settled in the sedimentation tank, and then the clear liquid overflows from the top and is directly discharged into the external environment. In fact, the overflow liquid directly discharged from the top of the settling tank contains excessive solids and fails to meet the national environmental protection discharge requirements, and there are serious safety and environmental protection risks. During the process, the scouring effect of the liquid will reduce the filtering effect or even destroy the filter screen. The solids contained in it will flow through the filter screen with high-speed water. When the filter device is used for a long time, it will also cause sludge accumulation. The cleaning and replacement of the device will affect the efficiency of the filtration, the cleaning is difficult and complicated, and the cost of migrant workers is increased in the process, which will adversely affect the economic benefits of the enterprise.
