目的了解崂山区农村集中式供水水质卫生状况,为加强农村饮水安全工程建设和管理提供科学依据。方法于2010年-2012年在崂山区选取20个集中供水点,于枯水期和丰水期分别进行水样采集和检测。结果三年共采集检测水样600份,总合格率为42.8%;丰水期和枯水期水样合格率差别有统计学意义(χ2=39.3,P<0.01);完全处理和未完全处理水样合格率差别有统计学意义(χ2=45.6,P<0.01);共检测19项指标,不合格指标9项,其中浑浊度、菌落总数、总大肠菌群和耐热性大肠菌群在不同水期、不同处理方式之间差别具有统计学意义。结论崂山区农村集中式供水水质合格率较低,以细菌学指标超标为主,枯水期合格率高于丰水期,经过完全处理的水样合格率高于未完全处理的水样。
Objective To understand the sanitation of centralized water supply in Laoshan district and to provide a scientific basis for strengthening the construction and management of rural drinking water safety project. Methods From 2010 to 2012, 20 centralized water supply points were selected in Laoshan District, and water samples were collected and tested respectively in dry season and wet season. Results In the three years, a total of 600 water samples were collected, with a total pass rate of 42.8%. There was a significant difference in pass rates between wet and dry water samples (χ2 = 39.3, P <0.01). Complete and incomplete water samples There were statistically significant differences between the two groups (χ2 = 45.6, P <0.01). Nineteen indicators were detected and nine were unqualified. The turbidity, the total number of colonies, the total coliforms and the heat-resistant coliforms in different water Period, the difference between different treatment methods has statistical significance. Conclusion The qualified rate of rural centralized water supply in Laoshan district is low, with the bacteriological index exceeding the standard, the passing rate in dry season is higher than that in wet season, and the pass rate of the completely treated water sample is higher than that of the incompletely treated water sample.
