Problems solved by technology

[0003] On the other hand, during the treatment process of the sewage treatment plant, the sewage first flows into the coarse grid, and after the larger floating debris is removed through the coarse grid, then the sewage is removed through the fine grid to remove the fine floating debris, and then in the swirling flow. The sediment is removed in the grit chamber, and the sediment deposited at the bottom of the grit chamber is discharged into the sludge storage tank through the sand suction machine; the sewage after sand removal enters the coagulation sedimentation tank of the back-end treatment facilities and equipment, such as the coagulation sedimentation tank It mainly removes suspended solid particles in sewage, and the floc particles formed by coagulation are small, light in weight and poor in sedimentation performance. This sewage treatment has brought great challenges

Abstract

The invention relates to the technical field of environmental engineering. The invention particularly discloses a coagulation-air flotation-agglomeration rapid separation system which comprises: a sewage tank, a sewage inlet pipe, an acid and alkali adding pipe, a coagulant adding pipe, a sewage pump, a first connecting pipe, a first drainage pipe, a gas dissolving pump, a gas inlet nozzle, a second drainage pipe, a first coagulant aid adding pipe, a copolymerization reactor box body, a second coagulant aid adding pipe, a stirrer, a stirring rod, a flow guide pipe, a separation device box body, a partition plate, a sludge collecting pipe, a scum collecting tank, a purified water collecting pipe, a third connecting pipe, a purified water collecting tank and a water outlet pipe. The system can effectively treat residual impurities in the sewage treated by the coagulating sedimentation tank, is simple in treatment operation and low in treatment cost, can effectively remove suspended particles, emulsified oil, fibers, heavy metals and other impurities in the sewage, and is environment-friendly and pollution-free.

Description

Technical field [0001] The invention relates to the technical field of environmental engineering, in particular to a rapid separation system for coagulation air flotation copolymerization. Background technique [0002] As our country's population continues to increase, water resources have been severely damaged, and our country is facing the problem of water exhaustion. Water resources are the guarantee for human survival. It is a non-renewable resource. It not only affects people's production and life, but also has an important impact on my country's urban construction and the improvement of my country's comprehensive national strength and international competitiveness. This shows that it is urgent to strengthen our country's urban sewage treatment work. However, in recent years, my country has caused serious problems of water pollution during the process of urbanization. The discharge of urban sewage is increasing, and the main sources of wastewater pollution in my country ar...
