Description

A sewage treatment device for water conservancy projects

Technical Field

The utility model relates to a sewage treatment device for water conservancy projects, belonging to the field of water conservancy projects.

Background technique

Water conservancy projects are used to control and allocate natural surface water and groundwater, involving the flow and transportation of fluids, mainly water and sewage. The construction of water conservancy projects plays an important role in irrigating farmland, transporting water resources to water-deficient areas, and supporting urban water demand. However, sewage is inevitably generated during the construction and use of water conservancy buildings. Direct discharge of sewage is likely to pollute the environment and seriously affect the quality of domestic water. Sewage treatment equipment can correctly and efficiently treat sewage.

Impurities in existing sewage treatment devices will accumulate on the filter, making it difficult to clean, and will affect the sewage filtration effect and reduce the service life of the filter. During the sewage treatment process, small particles of suspended matter are easy to accumulate at the bottom of the device. Existing devices are difficult to clean up the garbage remaining inside the device after sewage treatment, which can easily cause secondary pollution to the purified sewage.
