Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and in particular relates to a water supply and drainage sewage pretreatment device. Background Art

[0002] The pretreatment stage of water supply and drainage sewage mainly includes the following treatment methods: physical method, using the principle of gravity separation (sedimentation or flotation), through sedimentation tanks, sedimentation tanks and grease traps and other equipment to remove suspended pollutants in the water; filtration method, using filter media to intercept suspended matter in sewage, such as screens, sand filters and other equipment; flotation method, using tiny bubbles to carry pollutants to the water surface to achieve separation; centrifugal separation method, using centrifugal force to separate suspended particles, such as cyclone separators and centrifuges; in addition, the pretreatment stage may also include steps such as pre-aeration to reduce the degree of sewage corruption. These methods help to remove large particles and fine suspended matter in sewage, and prepare for subsequent biological treatment or other more sophisticated treatment steps. When using gravity to separate sediment, water supply and drainage sewage pretreatment equipment will be used.

[0003] The existing water supply and drainage sewage pretreatment devices still have some defects. Most of them do not have the function of automatic cleaning of the filter. After the filter is used for a long time, a large amount of sludge will accumulate on its surface, which may cause blockage of the filter and make it unable to be used normally. For this reason, we propose a water supply and drainage sewage pretreatment device. Utility Model Content
