2014年济宁市农村生活饮用水水质监测与分析

摘要

Objective To investigate the quality of drinking water in rural areas in Jining,and to provide refer-ences and basis to related policies and measures.Methods In 2014 Centers for disease control of Jining monitored the quality of drinking water in rural areas and urban areas,including sensory indictors and microbial indictors of the drinking water.Results There was no difference of all the sensory indicators between urban and rural drink-ing water.There were significance differences of total coliform groups and heat-resistant coliforms in wet period between urban and rural drinking water (χ2 =13.911,P =0.000;χ2 =4.274,P =0.039),but was no difference of total numbers of colonies (χ2 =0.243,P =0.622).All microbial indictors in dry period had significance differ-ences.Conclusion In 2014,drinking water in rural areas was poor,the differences between urban and rural drink-ing water mainly existed in the microbial indicators.%目的：调查2014年济宁市农村生活饮用水的水质情况，为以后改善和提高生活饮用水水质提供科学依据。方法根据 GB 5749-2006《生活饮用水卫生标准》，于2014年对济宁市农村及城市生活饮用水进行了感官指标及微生物指标监测分析。结果在感官指标中，城市和农村的合格率差异均无统计学意义。在微生物指标中，丰水期城市与农村生活饮用水的总大肠菌群合格率差异有统计学意义（χ2＝13．911，P ＝0．000）；耐热大肠菌群的合格率有统计学意义（χ2＝4．274，P ＝0．039）；菌落总数的合格率无统计学意义（χ2＝0．243，P ＝0．622）；枯水期城市与农村生活饮用水的微生物指标均有统计学意义。结论2014年济宁市农村生活饮用水水质较城市的差，主要体现在微生物指标。
