Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering sewage treatment, and more specifically, to a preliminary filtering structure for municipal engineering sewage treatment. Background Art

[0002] Municipal infrastructure projects refer to the civil engineering, pipeline and equipment installation projects of urban roads, public transportation, water supply, drainage, gas, heat, gardening, sanitation, sewage treatment, garbage disposal, flood control, underground public facilities and ancillary facilities.

[0003] Sewage usually refers to the water discharged from life and production that is polluted to a certain extent. Sewage mainly includes domestic sewage, industrial wastewater, initial rainwater and water samples containing hazardous chemicals or uncertain hazardous properties. The main pollutants in sewage include pathogen pollutants, oxygen-depleting pollutants, plant nutrients and toxic pollutants.

[0004] Authorization announcement No. CN 213253210 U discloses a pre-treatment filter device for sewage treatment. The device arranges an electric push rod at the bottom of the sewage filter plate so that the sewage filter plate can rotate along the box body after being blocked and the filtered impurities can slide into the collection box. However, when the device collects impurities on the filter screen, the electric push rod at the bottom of the filter screen is always in contact with the sewage. Over time, the sewage will cause certain corrosion to the electric push rod, which is easy to cause damage to the electric push rod. In addition, impurities are easily adsorbed above the sewage filter plate and are not easy to roll into the collection box by their own gravity alone. Therefore, there is room for improvement in the device.

[0005] In view of this, research and improvement are carried out on the existing problems, and a preliminary filtration structure for municipal engineering sewage treatment is provided, aiming to solve the problems and improve the practical value through this technology. Utility Model Content
