摘　　要：目的探讨农村集中式供水管网末梢水的浊度水平以及浊度对微生物等其他水质指标的影响,为水浊度的控制措施提供依据。方法对来源于2006年全国农村生活饮用水与环境卫生调查现状调查的农村集中式供水水质浊度的数据进行描述性和相关性分析。结果农村集中式管网浊度平均水平在3NTU左右,不同水源类型、水处理工艺的水厂管网末梢水浊度水平存在差异,以地面水为水源的水厂末梢水浊度高于以地下水为水源的水厂,浊度与细菌总数、总铁存在正相关关系。结论浊度是农村集中式供水工艺控制中的一个重要的参数,其水平受多种因素影响,同时对消毒效果有影响。Objective To know the turbidity level of tap water and its effect on the other water indexes, such as microbial index, in centralized drinking water supply in rural areas. Methods The descriptive and relative analyses were carried out based on the data of National Survey of Rural Drinking Water and Sanitation in 2006, China. Results The average level of turbidity was about 3 NTU in centralized rural water supply. There was a difference of turbidity level among various water source types and water treatment processing. There was a positive relationship between the turbidity and the total count of bacteria, total iron. Conclusion One important parameter is the turbidity in water treatment processing of centralized water supply. The turbidity levels are affected by various factors, and the turbidity can affect disinfection efficiency.
