Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an underground high-efficiency biofilm sewage treatment device. Background Art

[0002] With the growth of economy and population, environmental pollution issues are receiving more and more widespread attention. The top ten environmental issues in China refer to air pollution, water pollution, garbage disposal, land desertification and sand disasters, soil erosion, drought and floods, biodiversity destruction, WTO and environmental issues, environmental issues in the Three Gorges Reservoir area and persistent organic matter pollution. For water pollution, sewage is one of the important sources of pollution, and sewage is generally treated by ground-based treatment devices. With the rapid development of my country's national economy and the continuous advancement of urbanization, urban multi-point source water pollution is no longer suitable for large-scale sewage treatment plants. Large-scale sewage treatment plants are not only complex in equipment and occupy a large area, which will inevitably increase the land cost. The high cost of small-scale sewage treatment and complex equipment have become problems that need to be solved urgently.

[0003] When sewage passes through an underground sewage treatment device, it is first intercepted by a grid to intercept large-volume solids mixed in the sewage, and a filter with an aperture smaller than the grid is set to filter other impurities in the sewage, and then various subsequent sewage treatment measures are carried out to improve the sewage treatment efficiency; however, in the prior art, there are no corresponding cleaning measures for the grid and the filter that intercept impurities in the sewage. After being used for a period of time, the surface of the grid and the filter is blocked by mud and impurities in the sewage, which will affect the flow rate of sewage passing through per unit time, thereby reducing the working efficiency of the sewage treatment device.
