摘要: 以嘉兴市某水厂砂滤水为研究对象,采用超声波/紫外协同次氯酸钠对其进行消毒处理。结果表明,组合消毒工艺的最佳工艺参数:次氯酸钠投加量1.60 mg/L,HRT 50 min。相比单独次氯酸钠消毒,组合消毒工艺的次氯酸钠投加量减少18%,包括三卤甲烷、卤乙酸在内的5种消毒副产物(DBPs)总量减少44%。该组合消毒工艺实现了高效消毒和控制消毒副产物的统一。

Abstract: Using the sand-filtered water from a water plant in Jiaxing,China,as research target,the combined process,US/UV-sodium hypochlorite disinfection,has been applied to the disinfection treatment of sand-filtered water. The results show that the optimal parameters of the combined disinfection process are as follows:sodium hypochlorite dosage is 1.60 mg/L,and HRT 50 min. Compared with single sodium hypochlorite disinfection,the sodium hypochlorite dosage in the combined disinfection process is decreased by 18%,and the total amount of five kinds of disinfection by-products(DBPs),including trihalomethanes and haloacetic acid,are decreased by 44%. This combined disinfection process has realized the integration of efficient disinfection and the control of disinfection by-products.
