Description

Technical Field

[0001] The utility model relates to the relevant field of sewage treatment, and in particular to a multi-stage flocculation and stirring device. Background Art

[0002] Sewage treatment is a complex and sophisticated technical project. Its core goal is to remove various pollutants in domestic sewage and industrial wastewater to meet discharge or reuse standards, protect the quality of the water environment, and promote the sustainable use of water resources. With the increase in population and the intensity of human activities, the amount of sewage generated has increased dramatically. The organic matter, nitrogen and phosphorus nutrients, pathogenic microorganisms, heavy metals and other harmful substances contained in it pose a serious threat to the aquatic ecosystem and human health. Therefore, the development of efficient and environmentally friendly sewage treatment technology has become an important task for global environmental protection.

[0003] Traditional sewage treatment flocculation and stirring devices usually adopt one-stage flocculation and stirring, and the stirring effect is uneven and the treatment efficiency is low, so multi-stage flocculation and stirring systems appear on the market. The existing multi-stage flocculation and stirring systems are usually composed of multiple independent stirring units. The connection between these units requires complex pipeline and interface design, which is inconvenient to connect and use. In addition, after the existing flocculation and stirring devices flocculate the sewage, it is usually necessary to manually remove the residue produced by flocculation, which is troublesome. Therefore, we make improvements on this and propose a multi-stage flocculation and stirring device. Utility Model Content
