摘要
目的了解上海市集中式供水的水质现况。方法于2006年对上海市集中式供水单位的日常卫生管理情况进行调查,并按照卫生部《生活饮用水水质卫生规范》(2001)对水源水、出厂水进行水质检测,对管网末梢水进行水质抽检。结果对165家集中式供水单位(其中19家为自建供水单位)进行现场调查,卫生管理情况基本符合要求。对水源水、出厂水和管网水分别进行检测,其中水源水的耗氧量、总大肠菌群超标明显(超标率分别为63.93%和22.95%),出厂水和管网水的耗氧量、浑浊度和锰超标明显(出厂水超标率分别为25.45%,18.18%和27.88%,管网水分别为18.06%,13.89%和11.81%)。结论通过对165家集中式供水单位卫生管理现况及对水源水、出厂水、管网水的水质检测发现,当前最突出的问题仍是水源水有机物污染、水处理工艺落后和管网陈旧的问题。
Objective To understand the water quality of centralized water supply in Shanghai and provide the scientific data for further improvement of the health inspection and management of centralized water supply. Methods The management situation of centralized water supply, the water quality of water source, product water and tap water were investigated by using the methods in Analytical Methods for Water and Sanitary Standard for Drinking Water Quality (2001) in Shanghai in 2006. Results The current situation of management of 165 units of centralized water supply including 19 self-supply water plants in Shanghai was satisfactory. The analysis of drinking water showed that COD and total coliform in source water exceeded the standard limit remarkably(the eligible rates were 63.93% and 22.95% respectively), the eligible rates of COD, turbidity and manganese in product water and tap water were 25.45%, 18.18%, 27.88% and 18.06%, 13.89%, 11.81% respectively. Conclusion The results of the present investigation show that in Shanghai the main problems about the water quality are water source contamination by organic pollutants and the undeveloped water treatment.
