摘要
目的:分析某社区五户居民饮水同时受污染(水体呈天蓝色)的原因,提示大家在日常生活中加以重视。方法:监督人员到现场调查、观察、模拟试验,实验室对水样进行可疑项目检测,将水样同可疑污染物-固体洁厕净浸泡水作对照试验。结果:排除管道老化、腐蚀、地下渗漏造成的污染,对蓝色固体洁厕净浸泡水与受污染水样进行对照试验显示,理化性质完全一致。结论:高度怀疑为马桶贮水箱中放有固体洁厕净,由于停水形成管道负压,贮水箱中的水回流入供水管道引起饮水污染。
Objective：To investigate the cause of drinking water pollution of 5 families in a certain community to attract the reader attention in our daily life. Methods：Hygiene supervisors investigate, observe and simulate test on the spot and detect the suspicious project of water samples in the chemical laboratory, do the controlled test of water samples and the soaking water from suspected pollutants -solid auto cleaning agent for toilet. Results：Eliminate the pollution of pipeline aging, corrosion and underground percolation, the Physical and Chemical Properties of the soaking water from bule solid auto cleaning agent for toilet and polluted water samples are the same. Conclusion：Highly suspecte the pollution from solid auto cleaning agent for toilet.
