目的:了解本师生活饮用水水质现状,及时发现全师居民生活饮用水安全性中可能存在的问题,以便及时解决,持续性地确保全师生活饮用水安全。方法:于2013年—2015年连续三年按国家标准方法全面检测全师生活饮用水水质。结果:本师生活饮用水目前存在的主要问题是氯化物、硫酸盐、溶解性总固体、总硬度、氟化物、细菌总数等指标存在一定水平且相对稳定的超标率。结论:本师生活饮用水目前感官性状良好,暂不存在化学毒物及粪便污染问题,但水中可溶性盐类含量有一定超标率,这与地下水泾流区域水溶性化学成分有关。因此,本师饮用水安全性防患重点宜侧重于进一步普及集中式供水并进一步强化其经常性卫生防护工作。
Objective: To understand the status quo of the drinking water quality of this division and find out the problems that may exist in the safety of drinking water for all residents in order to solve and ensure the safety of potable water throughout the school. Methods: From 2013 to 2015 for three consecutive years according to the national standard method to fully test the quality of drinking water throughout the division. Results: The current main problems of drinking water in our institute are the over-standard rate of chloride, sulfate, total dissolved solids, total hardness, fluoride, total bacteria and other indicators of a certain level and relatively stable. CONCLUSION: At present, the physical and chemical properties of drinking water in our institute are good at present. There is no problem of chemical poisons and excrement pollution temporarily. However, the content of soluble salts in water has exceeded the standard, which is related to the water-soluble chemical composition of the groundwater flow. Therefore, the main focus of prevention and control of drinking water safety should focus on further popularizing centralized water supply and further strengthening its regular health protection work.
