Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and in particular relates to a multi-layer screening machine for a sewage treatment plant. Background Art

[0002] Sewage treatment can be very important, which can be proved from the following aspects: Purify water quality: Sewage treatment can effectively remove harmful pollutants in water, purify water quality, and ensure the safety and cleanliness of water resources. Prevent the spread of diseases: Sewage contains a large number of germs and pathogens. If it is not treated, it is easy to cause the spread and prevalence of diseases. Through sewage treatment, the risk of disease transmission can be reduced. Protect the ecological environment: Untreated sewage will be directly discharged into natural water bodies, causing serious pollution to the ecological environment, endangering aquatic organisms and ecological balance. Treated sewage can reduce damage to the environment and protect the health of the ecosystem. Save resources: Sewage contains a certain amount of organic matter and nutrients, which can be reused after treatment, reducing resource waste and improving resource utilization efficiency. Improve the image of the city: Effective sewage treatment can improve the environmental quality and quality of life of the city, improve the image of the city and the satisfaction of residents. The filter in the sewage treatment plant is a device used to remove solid particles and other impurities in sewage. It usually adopts structures such as screens, filters or filter plates, and uses the principle of physical filtration to retain solid particles in sewage on the screens or filter plates, thereby purifying the water quality. However, ordinary screening machines need to be cleaned after filtering for a period of time, which greatly affects the filtration efficiency. In addition, single-layer filtration is generally used, and the filtration effect is not good enough.
