The filter plate includes: a filter plate body; The filter plate body forms an angled wing plate; the filter plate body is provided with a plurality of through holes; the plurality of through holes are arranged in multiple rows, and the filter plate of the present invention can be assembled with the filter frame, which bears high pressure, It is not easy to be damaged and will not block the feeding port.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a filter device for sewage treatment. Background technique [0002] In recent years, the state has invested a lot of money in the planning and construction of sewage pipe networks and sewage treatment plants, and the air environment has been greatly improved. However, due to age, some old urban areas, schools, factories, etc. currently discharge domestic sewage and industrial sewage directly into ditches, streams, and rivers through catchment ditches, causing damage to the air and environment in some areas. The technology commonly used in the prior art is to bury one end of the collection pipe in the wall, use a brick overflow wall nozzle to collect sewage with a floor drain cover, and connect the other end to the sewage pipe network. The disadvantage of this treatment method in the prior art is that debris will be caught when they drift to the nozzle, and the nozzle needs to be cle...

AI Technical Summary

Problems solved by technology

The disadvantage of this treatment method in the prior art is that debris will be caught when they drift to the nozzle, and the nozzle needs to be cleaned manually if the nozzle is blocked. If the drain cover is damaged during cleaning, if it is not replaced in time, debris and large-grained sand will enter the sewage for a long time The sediment in the pipe network is deposited in the inverted siphon, which directly affects the sewage operation
