Study on Emergency Treatment Mode of Algae in Water Plant Raw Water of the South-to-North Water Diversion Project
In the past two years,the algae in the water source of the mid-route of the South-to-North Water Diversion Project has increased significantly,which has led to the blockage of the intake of the water supply plant,and the sharp reduction of the treated water volume,and seriously affected the normal operation of the water supply plant.Most of the emergency treatment measures of algae in water plant raw water of South-to-North Water Diversion Project are the combination of physical filtration and interception and chemical oxidation treatment to effectively remove algae pollution.Different areas and different types of projects adopt different emergency treatment modes for raw water algae outbreaks.Many of the water plants in operation install artificial grid and auxiliary chemical agents to pre-oxidize algae pollution,which is simple in operation and maintenance with relatively low cost.The water plants under construction install special facilities for interception and removal of algae,such as mechanical grid and artificial grid switch mode.By taking the physical method of filtration interception and chemical oxidation treatment combined emergency combination treatment measures,the algae and other water pollution hazards could be solved permanently.
