摘要
研究了净水厂采用次氯酸钠作为消毒剂时对水中氯酸盐含量的影响。结果表明,次氯酸钠产品中含有氯酸盐,且随着储存时间的延长,有效氯衰减、氯酸盐含量增加;通过小试和中试得出,出厂水中的消毒副产物氯酸盐主要来自该消毒剂产品。
The effect of sodium hypochlorite used in waterworks as disinfectant on chlorate concen- tration in water was investigated. The results showed that sodium hypochlorite products contained chlo- rate, and with increase in storage time, the available chlorine was decreased, and the chlorate concentra- tion was increased. According to jar test and pilot-scale experiments, the chlorate in the finished water was the by-product from the sanitizer.
