Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment filtering device. Background Art

[0002] Among the water pollution caused by human production activities, the water pollution caused by industry is the most serious. For example, industrial wastewater contains many pollutants and has complex components. It is not only difficult to purify in water, but also difficult to treat. Industrial wastewater is the most important cause of water pollution caused by industrial pollution. It accounts for the majority of pollutants discharged by industry. The pollutants contained in industrial wastewater vary greatly depending on the type of factory. Even for the same type of factory, the quality and quantity of pollutants contained are different due to different production processes. In addition to the direct injection of industrial wastewater into the water to cause pollution, solid waste and exhaust gas can also pollute the water.

[0003] Sewage contains a large amount of impurities. When using existing sewage filtering devices, it is not convenient to discharge the filtered impurities after filtering the sewage. After the sewage is filtered, the filtering device needs to be cleaned again before it can be used again, which brings trouble to the use of the filtering device. Therefore, we propose a sewage treatment filtering device. Utility Model Content
