Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering, in particular to a filtering device for municipal drainage. Background Art

[0002] As we all know, when conducting municipal sewage treatment, it is usually necessary to filter the sewage to achieve solid-liquid separation of the sewage to facilitate subsequent sewage treatment. Sewage treatment can avoid the pollution of the environment by direct sewage discharge, which is of great significance in modern society.

[0003] Existing municipal engineering wastewater discharges wastewater directly through water pipes to output the wastewater into drainage pipes, and the drainage pipes transport the wastewater to treatment stations for treatment. However, the wastewater contains a lot of impurities. If it is not simply filtered, it is easy to clog the water pipes for a long time. Once the water pipes are blocked, they need to be manually unblocked, which not only increases the workload of the workers, but also delays the workers' working time. Therefore, a filtering device for municipal drainage is needed. Utility Model Content
