Study on the technology of vortex coagulation and its application in water plant of DongFeng motor corporation

After a brief introduction to the core parts of vortex coagulation technology, such as the characteristics of the vortex reactor, and its working mechanism with contact-flocculation, this paper emphasizes that the critical point of this technology lies in the determination of the opening diameter on different surfaces and the control of the opening rate. Through the following illustration of its application on accelerator in a water supply plant in Shiyan in which the treatment scale of the accelerator is increased from 1,280 to 2,500 m³/h, the effluent turbidity of the accelerator is lower than 3 NTU and the effluent turbidity of finished water is lower than 1 NTU, the investment of per ton water is lower – 30 yuan RMB. The paper argues that in comparison to other coagulation reactors, the vortex reactor deserves wider application for its various advantages, such as its higher coagulation efficiency, shorter reactivity time, better quality of finished water, stronger adaptive capability, convenience in construction and so on.
