In view of dual water sources water supply of Qiantang River and Qiandao Lake water in J water treatment plant(WTP),the effects of mixing ratio of different water sources on water quality of raw water,water quality of effluent,consumption of coagulants,disinfectants,polyacrylamide(PAM)and power consumption of water operation were analyzed.The results showed that compared with the last year at the same time,the increase in the proportion of high-quality raw water from Qiandao Lake improved the quality of raw water in WTP,and the turbidity and potassium permanganate indices decreased by 26.18%and 12%.When the proportion of Qiandao Lake water source in the mixed raw water was above 95%,the turbidity of produced water decreases by 50%at most,and the electricity consumption of water production decreased by 25.30%.The coagulant consumption decreased by 60.29%,and the consumption of secondary sodium decreased by 23.82%at most.And the sludge production and PAM consumption were about 66.91%and 65%of the 25%mixing ratio,which makes the operation of WTP more economic and efficient.
