为确保密云区农村饮水卫生质量,对水源的保护、水质处理、水质监测及水厂管理等进行了分析.其中水质处理中的消毒工艺是保证卫生质量的主要环节。密云区的实际情况调查表明,保证卫生安全的主要手段是:①采用水源净水工艺去除或降低原水中对人体有害的悬浮物质、胶体、有害细菌、病毒以及溶解于水中对人体有害的物质;②对水中的微生物进行消毒处理。目前,主要采取二氧化氯、臭氧消毒进行水处理,通过对二氧化氯、臭氧消毒工艺进行科学设计,密云区农村饮水微生物指标的合格率已明显提高。密云区通过加强水源保护、强化水质处理工艺、建立健全水质监测体系等.实时掌握水源地水量水质状况,实现了保证农民饮水达到GB 5749-2006《生活饮水卫生标准》要求。
In order to ensure the hygiene quality of rural drinking water in Miyun District, the protection of water sources, water quality treatment, water quality monitoring and water plant management were analyzed, among which the disinfection technology in water quality treatment was the main link to ensure the hygiene quality. The actual situation of Miyun district survey shows that the main means to ensure health and safety are: ① the use of water purification process to remove or reduce the raw water of harmful substances in the human body, colloids, harmful bacteria, viruses and dissolved in water harmful to human health substances; ② disinfection of microorganisms in the water. At present, chlorine dioxide and ozone disinfection are mainly adopted for water treatment. Through scientific design of chlorine dioxide and ozone disinfection technology, the passing rate of microbial indicators of drinking water in rural areas of Miyun has been significantly improved. Miyun District by strengthening the protection of water resources, strengthen water treatment process, establish and improve the water quality monitoring system, etc. Real-time control of water quality and quantity of water sources to achieve the guarantee of drinking water to reach the standard of 5757-2006 “drinking water health standards.”
