摘要
从饮用水氯化消毒效果考虑,研究消毒的影响因素,确定最适的消毒条件,并对消毒副产物进行分析,弄清其形成的机理和成因,从替换消毒剂和消毒方法中综合介绍、分析了各种消毒剂的特点、优势,以及存在的不足。从去除消毒副产物前驱物质,加氯过程中应该注意的问题,去除已生成的消毒副产物,对国内外控制饮用水消毒副产物的研究进展进行综述。通过实验得出在不同的条件下(如pH,消毒时间,有效氯的量),水样消毒的变化规律,同时利用离子色谱仪,对水样消毒后消毒副产物的变化规律进行研究(包括氯酸根,次氯酸根,溴酸根),通过总结出水样消毒的变化规律,已利于对饮用水的消毒进行充分的研究。
From the aspect of chlorination disinfection effect of potable water,influencing factors for the sterilization were analyzed,the best sterilization conditions were determined,byproducts of the sterilization were also analyzed,forming mechanism and causes of byproducts were determined.Advantages and disadvantages of different disinfectants were introduced.Research progress in eliminating byproducts of the sterilization was discussed.The sterilization results under different conditions（pH,sterilization time,dosage of chlorine） were compared.The change of sterilization byproducts（including chlorate,hypochlorite etc.） was studied by ion chromatograph.
