Technical Field

[0001] The utility model belongs to the technical field of sewage treatment devices, and in particular relates to a dry-wet separation sewage treatment device. Background Art

[0002] A sewage treatment plant is a device used to treat sewage. Its main purpose is to remove or reduce harmful substances in sewage to meet the requirements of environmental protection and water resource management. Sewage treatment plants are widely used in the treatment of urban domestic sewage and industrial wastewater to prevent sewage and pollutants from flowing directly into water bodies. They are of great significance to improving the ecological environment, enhancing the quality of cities and promoting economic development.

[0003] During the process of screening sewage by the inclined screen of the existing dry-wet separation sewage treatment device, the filter holes on the surface of the inclined screen will be blocked by impurities in the sewage, thereby reducing the screening efficiency of the inclined screen. At the same time, after the inclined screen screens the sewage, the impurities adhered and retained on its surface cannot be cleaned, which will affect the next sewage screening of the sewage treatment device. Therefore, a dry-wet separation sewage treatment device is needed to solve the above problems. Utility Model Content
