摘要
目的调查顺德区农村集中式供水水厂的卫生现况、制水工艺流程和卫生管理情况,水源水和出厂水水质状况。方法制定的“农村集中式供水单位基本情况调查表”,现场调查各水厂的卫生现状,出厂水水质按《生活饮用水标准检验规范》(2001)检验评价。结果供水厂取得卫生许可证百分比仅是70.8%,提示我们的卫生工作必须向村一级基层单位深入渗透。各水质的硬件设施较好,长期投加水处理剂的厂家达到80%以上,但投加有卫生许可批件的消毒剂的水厂仅6家,占25.0%。结论顺德区水源水质量不理想,以化学污染为最严重,出厂水的水质合格率高,这是充分肯定了顺德区水厂的水处理过程完全、必须设备的拥有率和自动化程度高是保证出厂水质的前提。
Objective To investigate the current hygienic conditions of concentrated water supply,the system of watercraft process and the ability of water factories hygienic management,the quality of fresh water and drinking water. Methods To establish investigation table and survey the hygienic conditions of water factories;the quality of water is inspected by'sanitary standard for drinking water quality' (2001). Results The percentage of rural water factories with hygiene permit was 70.8% only,The facilities of each water factory were acceptable,the percentage of factories which hurled the chemicals used usually attained above 80%,but the number of factories which used chemicals with hygiene permit was only 6,occupying 25.00%. Conclusion Our hygiene work must face the skeleton units and enhance inspection and management. The fresh water was not very good with serious chemical pollution but the qualified rate of drinking water was high,which shows that the complete watercraft process is crucial and the high rate of automatic equipments use is a premise to guarantee the quality of drinking water.
