摘　　要：上海某百万吨级给水厂深度处理工程总规模100万m^(3)/d,采用预臭氧进行预处理,臭氧-生物活性炭工艺作为深度处理工艺对水厂进行升级改造。将原水厂4个分散系统深度处理工程整合为1~3系统融合的(规模80万m^(3)/d)深度处理与独立4系统(规模20万m^(3)/d)深度处理两部分。将消毒方式改为多点加注,不仅降低了加注量,同时也减少了消毒副产物的产生,最大程度发挥了消毒效果。出厂水水质指标均达到《生活饮用水卫生标准》(GB 5749—2006)要求,同时对全厂的排水进行了“三分离”系统改造,减少了对周围水体的影响。The total production scale of the deep treatment project for a water supply plant in Shanghai is 1 million m^(3)/d.The project adopted pre-ozone for pretreatment,and the ozone biological activated carbon process was used as the advanced treatment process.Integrate the four decentralized system deep treatment projects of the raw water plant into two parts:a 1-3 system fusion(scale of 800000 m^(3)/d)deep treatment and an independent 4 system(scale of 200000 m^(3)/d)deep treatment.The transformation adopted multi-point injection,which not only reduced the injection amount but also reduced the generation of disinfection by-products,maximizing the disinfection effect.The water quality indicators of the factory water all met the requirements of the Standard of drinking water quality(GB 5749-2006),and the drainage system of the entire plant has undergone a“three separation”system transformation to reduce the impact on the surrounding water bodies.
