Description

Technical Field

[0001] This utility model belongs to the field of water supply and drainage filtration technology, and in particular relates to a filtration device for municipal water supply and drainage. Background Technology

[0002] Municipal water supply and drainage generally refers to the urban water supply system and drainage system, or simply water supply and drainage. Water supply projects are projects that supply domestic and industrial water to residents, factories, mines and transportation enterprises, as well as fire-fighting water, road greening water, etc. It consists of water source, water intake structure, raw water pipeline, water treatment plant and water supply network. It has the function of collecting and transporting raw water and improving water quality. During municipal drainage, impurities may be mixed in the water, which can easily cause blockage of water supply and drainage pipes.

[0003] Existing municipal drainage devices typically only have one or two filters at the water inlet, which can only filter impurities but cannot collect and discharge them. This results in impurities accumulating at the water inlet filter, affecting drainage efficiency. To address this, we provide a municipal water supply and drainage filtration device to solve the aforementioned problems. Utility Model Content
