Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more specifically to sewage treatment equipment for environmental protection engineering. Background Art

[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. Sewage treatment is an important aspect of environmental protection projects. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care and catering. When treating sewage, it is first necessary to use sewage treatment equipment to filter solid impurities in the sewage, and then treat the filtered sewage.

[0003] When using sewage treatment equipment to filter solid impurities in sewage, a common method is to inject sewage into a tank or box, and then use the filter net inside the tank or box to filter the solid impurities to achieve the effect of separating the solid impurities and water. However, in the use of the above-mentioned traditional sewage treatment equipment, solid impurities will adhere to the surface of the filter net, reducing the filtration efficiency of the filter net, and after use, the surface of the filter net needs to be cleaned, but due to the narrow space inside the equipment, it is difficult to clean, which in turn affects the subsequent use of the equipment.

[0004] In view of this, the utility model proposes a sewage treatment equipment for environmental protection engineering to solve this problem. Utility Model Content
