Based on Urban Water Quality Improvement and Security Countermeasures during Major Events of Hangzhou Asian Games
Focusing on the improvement of water quality guarantee during the Asian Games,this paper studied the water quality of raw water of Qiantang River in the event of water quality emergencies such as high algae,high pH and salty tide,analyzed the correlation between conductivity and chloride,adopted laboratory pilot co-production experiments,online and offline linkage monitoring,strengthened water quality monitoring from the source to the head,and proposed efficient and feasible water quality emergency disposal schemes.The results showed that when the pH value of raw water was ≥7.8,the pH and aluminum content of effluent could be effectively reduced by using CO2 to adjust pH.The algae removal efficiency of potassium permanganate combined with deep water were more than 99.6％.There was a positive correlation between the conductivity and chloride.When the conductivity of raw water was greater than 500 μS/cm,it could be used as the early warning threshold of salt tide in Qiantang River.At the same time,the internal and external linkage is taken to ensure the special water quality of the Asian Games,to bid for the new national standard,raise the standard and increase the item,to provide strong support for the quality water supply of the 19th Hangzhou Asian Games in 2022,and to provide practical reference for the water quality assurance of major events in other regions.
