目的了解2011年梧州市农村卫生饮用水卫生状况,为下一步开展农村生活饮用水的卫生监测工作提供依据。方法以《2011年广西农村生活饮用水水质卫生监测技术方案》为依据,选择市直管的30处已经建成投入使用的农村集中式供水工程及市长洲区5处分散式供水为监测点,于枯水期和丰水期各采集集中式供水出厂水和末梢水各1份水样,分散式供水采集农户家庭储水器(家中水龙头)水样1份进行监测。结果梧州市农村生活饮用水共采集水样130份,水质总的合格率为55.38%,枯水期和丰水期的合格率分别为53.85%(35/65)和56.92%(37/65);集中式供水的合格率为56.67%(68/120),分散式供水的合格率为40.00%(4/10)。不同类型水源的水质合格率以深井水最高,其次为浅井水,最低是地表水,合格率分别为94.44%、83.33%、55.86%。水质完全处理的合格率为42.86%,不完全处理或不处理的水质合格率为56.90%。水质不合格的项目有浑浊度、菌落总数、总大肠菌群、耐热大肠菌群、铁。其中总大肠菌群不合格57份,耐热大肠菌群不合格56份,菌落总数不合格34份,浑浊度不合格40份,只有1份水样铁含量不合格。结论梧州市只有半数的农民的生活饮用水是安全的,农村生活饮用水存在最大的问题是受到微生物的污染。
Objective To understand the sanitary status of rural drinking water in Wuzhou in 2011 and provide the basis for the next step to carry out the sanitary monitoring of drinking water in rural areas. Methods Based on the “2011 Rural Drinking Water Quality Sanitation Monitoring Technical Program” in Guangxi, 30 centralized water supply projects in rural areas and 5 distributed water supply in Changzhou District were selected as the monitoring points in 30 cities under direct control. During the dry and wet periods, 1 water sample was collected from each of the centralized water supply and the peripheral water, and distributed water was collected to collect 1 water sample from the household water storage tank (at home). Results A total of 130 water samples were collected from rural drinking water in Wuzhou city. The overall qualified rate of water quality was 55.38%. The pass rates in dry season and wet season were 53.85% (35/65) and 56.92% (37/65) respectively. The passing rate of water supply was 56.67% (68/120), and the passing rate of distributed water supply was 40.00% (4/10). The water quality passing rate of different types of water sources is the highest in deep well water, followed by shallow well water, the lowest is surface water, the pass rates are 94.44%, 83.33% and 55.86% respectively. The qualified rate of complete treatment of water quality is 42.86%, the qualified rate of incompletely treated or untreated water quality is 56.90%. Unqualified water quality projects turbidity, the total number of colonies, total coliforms, heat-resistant coliform bacteria, iron. Among them, 57 cases of total coliforms failed, 56 cases of heat-resistant coliform failed, the total number of failed colonies 34, 40 turbid unqualified, only 1 water samples of iron content unqualified. Conclusion Only half of peasants in Wuzhou have safe drinking water. The biggest problem with drinking water in rural areas is that they are contaminated by microorganisms.
