ABSTRACT
Objective To evaluate sanitary quality of drinking water of small centralized water supply in rural areas using fuzzy comprehensive evaluation method.Methods Fifteen rural small centralized water supply facilities in Jinhua City were randomly selected.The health -related indicators were detected,and fuzzy comprehensive evaluation was used to evaluate the test results.Results The qualification rate of fifteen rural small centralized water supply facilities detected was 6. 67%.The qualified rate of the heat-resistant coliform bacteria in all items was 26. 67%,and the qualified rate of total coliforms was 6. 67%.The qualified rate of total numbers of colony,fluorid,chloride,sulfate,total dissolved solids, iron,oxygen consumption,total hardness and nitrate was all 1 00%.Sanitary quality of the water supply facilities was judged by the fuzzy membership evaluation.There were 4 water supply facilities evaluated as level Ⅰ(good),level Ⅱ(qualified ) and level Ⅳ (bad ) respectivley,and 3 water supply facilities evaluated as level Ⅲ (poor ).Fuzzy comprehensive index of sanitary quality was less than 0. 5 .Conclusion There is a risk of security in rural small centralized water supply water of Jinhua City.The low qualified rate of rural small centralized water supply water was due to heat-resistant coliform bacteria and total coliforms.The relevant departments should strengthen the hygiene management. Disinfection equipment should be installed,and standardized disinfection should be promoted to improve water quality.
