【摘要】 为保证饮用水给水管网的水质安全,通过现场实验对以二氧化氯为惟一消毒剂的典型管网进行连续试验检测,获得实际管网的二氧化氯消毒副产物亚氯酸盐和氯酸盐的变化规律并对其影响因素进行分析.结果表明,氯酸盐在实际管网中的量均小于0.05 mg/L,而亚氯酸盐在连接管、转弯管和支管的质量浓度分布明显偏低,说明实际管网中的管垢和流速是影响亚氯酸盐质量浓度变化的关键因素.实际管网内二氧化氯消毒副产物的调查分析对消毒剂的安全使用以及饮用水品质的提高具有重要意义.更多还原

【Abstract】 This paper was designed to study the concentration of chlorite and elucidate the factors on concentration of chlorite in drinking water pipe network disinfected by chlorine dioxide. The result showed that the lowest concentration of chlorite was connecting tube,elbow tube and branch in drinking water pipe network. The most important impact on chlorite was pipe sordes and flow rate. The transformation of chlorine dioxide disinfection byproducts in pipe network considered drinking water from safe to health play an important role.更多还原
