目的了解防城港市农村集中式供水的卫生状况,分析影响饮用水卫生安全的相关因素。方法每年对市本级辖区的所有乡镇进行代表性抽样,枯水期和丰水期各集中采水一次,出厂及末梢水各一份,进行相关理化及微生物检测。结果 372份水样总体合格率仅为34.95%,其中丰水期184份,合格率为28.26%,枯水期61份,合格率为41.49%,出厂水186份,合格率为38.71%,末梢水186份,合格率为31.18%,完全处理142份,合格率为73.97%,沉淀过滤或仅消毒50份,合格率为24.00%,未处理228份,合格率为5.70%,主要是菌落总数、总大肠菌群、耐热大肠菌群3项微生物指标超标。结论农村生活饮用水水质存在安全隐患,主要为没能按要求对水样进行相关的处理,对农村饮水条件的改善,应加大经济及技术方面的投入,加强农村集中式水厂管理及技术人员的培训,加强对水源地保护,加强对广大农民饮水安全相关知识的宣传。
Objective To understand the sanitary conditions of centralized water supply in rural areas in Fangchenggang and analyze the related factors that affect the hygiene and safety of drinking water. Methods Each year, representative samples were collected from all the towns and townships in municipal districts. Water was collected once in the dry season and wet season, and one in the factory and the peripheral waters respectively for physical, chemical and microbiological tests. Results The overall pass rate of 372 samples was only 34.95%. Among them, 184 were wet season, the pass rate was 28.26%, 61 were dry season, the pass rate was 41.49%, and 186 were manufactured water, the pass rate was 38.71% and the peripheral water 186 , The pass rate was 31.18%, completely processed 142, the pass rate was 73.97%, sedimentation filtration or sterilized only 50, the pass rate was 24.00%, untreated 228, the pass rate of 5.70%, mainly the total number of colonies, total Coliform bacteria, heat-resistant coliform bacteria exceeded the three indicators of microorganisms. Conclusion There are potential safety problems in the quality of drinking water in rural areas, mainly because the water samples can not be handled as required. Improving the drinking water conditions in rural areas should increase investment in economy and technology, and strengthen the management and technology of rural centralized water plants Personnel training, strengthen the protection of water sources, and strengthen public awareness of the vast number of peasants drinking water safety knowledge.
