为探讨饮用水卫生的科学管理方法 ,对芜湖市生活饮用水十年来的水质监测资料进行统计分析。结果表明十年内生活饮用水的出厂水和管网末梢水合格率上升趋势明显 ,采用液氯和二氧化氯联合消毒法前后出厂水细菌总数、铁、锰、铜均呈现显著性差异 (P <0 .0 5 ) ,苯并芘、氯仿、四氯化碳检出率明显下降。提示水源的污染治理、卫生监督和水厂的技术改造以及加强自身管理 ,是提高饮用水卫生质量的重要环节 ,液氯和二氧化氯联合消毒法的采用对提高饮用水水质有明显的效果。
In order to explore the scientific management of drinking water sanitation, a statistical analysis was made on water quality monitoring data of drinking water in Wuhu over the past 10 years. The results showed that the qualified rate of water excreted from the domestic drinking water and the end of the pipe network tended to increase significantly within ten years. The total number of bacteria in the ex-factory water before and after the combination of liquid chlorine and chlorine dioxide disinfection showed significant differences in iron, manganese and copper (P < 0 .0 5), benzopyrene, chloroform, carbon tetrachloride detection rate decreased significantly. Suggest that the pollution control of water sources, health supervision and technical transformation of waterworks and strengthen their own management, is an important part of improving the quality of drinking water hygiene, liquid chlorine and chlorine dioxide disinfection method used to improve the quality of drinking water has a significant effect.
