Measures for Algae Removal from Source Water Collected from Yellow River

每年的1—5月,由于黄河水污染,郑州中法供水公司的原水都会爆发藻类水华.为了保证供水水质,采取了缩短原水在调蓄池水力停留时间,在调蓄池放养花鲢和白鲢,投加硫酸铜,强化混凝以及增大加氯量等措施抑制并杀灭藻类,同时,投加粉末活性炭消除水中的嗅味.结果表明,这些措施经济、可靠.

Algaes have bloomed from January to May in source water of Zhengzhou Sino French Water supply Co,Ltd.because of Yellow River pollution.Measures were used,such as shortening the hydraulic retention time of source water in the regulating reservoir,raising silver carp and spotted silver carp in the regulating reservoir,adding copper sulphate into the regulating reservoir,enhancing coagulation by using polyaluminium chloride and sodium silicate,increasing chlorine dosage to remove algae in source water,and powder activated carbon was used to remove odor,which guaranteed the drinking water quality.The results show that,these measurements are economic and reliable.
