摘要
再生水消毒后主要作为城市杂用水利用，消毒副产物及其毒性的研究非常重要。在浓度为5～8mg／L的消毒剂（ClO2、HClO）量下，灭菌率能够达到100％。2种消毒体系均产生少量ClO2-、ClO3-；和CHCl3，对检验用水生生物未产生毒性。适当的选择消毒剂浓度，控制反应条件，能够实现再生水的安全回用。
The by-product formation and toxicity in reused water after ClO2 or HClO disinfection was stud- ied. The disinfection efficiency is 100% after disinfection of 5 - 8 mg/L ClO2 or HClO. The concentrations of ClO2- , ClO3 and CHCl3 were low in two disinfection systems. The disinfected reused water is safety under proper disinfect conditions.
