[0003] In the existing technology, sewage is mostly filtered through a filter plate with multiple filter holes to separate the sewage from the debris and foreign matter contained in the sewage. However, during the long-term and large-scale sewage treatment process, a large amount of debris and foreign matter accumulates on the filter plate and easily clogs the filter holes, thereby slowing down the flow of sewage and affecting the speed of sewage filtration. Utility Model Content

[0004] In order to reduce the possibility of debris clogging the filter holes and affecting the sewage filtration speed, the present application provides a sewage filtration device.
