南水北调天津受水区饮用水安全保障技术研究

Study on safety technology of drinking water in Tianjin water-receiving area of the South-to-North Water Diversion Project

围绕南水北调水进入天津市后的水质安全保障问题,研究了常规处理工艺对南水北调水的适应性和适合于南水北调水的水厂升级改造技术。结果表明,常规工艺对南水北调水具有极强的工艺适应性,出水水质指标优于国家标准。常规处理-臭氧活性炭和预臭氧-混合-炭吸附澄清-超滤这两种工艺均能有效去除水中的有机物,适合作为水厂的升级改造工艺。

Focused on water quality safety after adopting water of the South-to-North Water Diversion Project as raw water,the adaptability of the conventional treatment process to the water and upgrading technology of the water treatment plant suitable for the water were studied. The results showed that the conventional process had an extremely good adaptability to the water,and the effluent quality was superior to the national standards. The conventional treatment-ozone activated carbon and pre-ozone-mixed-carbon adsorption clarification-ultrafiltration were investigated,and both could effectively remove organic matter in water and be suitable as upgrading process for water treatment plant transformation.
