摘要
目的分析2014-2016年某市农村集中式供水水质卫生状况,为科学制定饮用水安全管理策略提供参考依据。方法使用Excel软件对2014-2016年某市农村集中式供水监测数据进行录入和整理,使用SPSS 20.0软件对数据进行分析。结果 2014-2016年某市共监测1 160份水样。出厂水合格率(90.86%)高于末梢水合格率(82.05%)。按地区统计,B县水质合格率较低;三县主要水源类型均为泉水;A县水处理方式以沉淀过滤为主,B、C两县大部分供水未经处理。丰水期末梢水水样合格率低于枯水期。水质不合格项目主要为微生物指标。结论某市农村集中式供水水质总体较好,但仍存在不合格因素,卫生状况存在隐患,应进一步加强对生活饮用水特别是末梢水的监管。
Objective To analyze the hygienic condition of rural centralized water supply from 2014 to 2016 in a city and to provide scientific management strategies of the safety of drinking water. Methods Use Excel to collect the data of monitoring rural centralized watar supply from 2014 to 2016 in the city,and analye the data with SPSS 20. 0. Results A total of 1 160 samples were monitored during 2014-2016. The qualified rate of the tap water（ 90. 86%） is higher than that of the end water（ 82. 05%）. The result of regional distribution have the following characteristics： the rate of water quality in B county is low; the main types of water are spring water in three county; the water treatment method is mainly precipitation filtration in a county; most of the water supply is untreated in B and C county. The qualified rate of water sample at the supply tap water in abundant water period is lower than that of drought period. The water quality unqualified project mainly is the microbial index. Conclusion The water quality of rural centralized watar supply in the city is good in a whole. Howerer,there were some potential safety hazard due to some unqualified factors. Therefore,further management of drinking water especially peripheral water should be enhanced.
