日本柴岛净水厂深度处理工艺

Study and Test on Advanced Water Treatment at Kunijima Water Purification Plant

本文介绍了日本大阪市柴岛净水厂深度处理工艺流程和处理效果 ;并通过实际测定和分析 ,指出了应用臭氧 -生物活性炭深度处理工艺 ,提高了对小于 30 0 0D分子量有机物的去除率 ,可以有效降低DOC、Euv等有机物指标 ;但要注意防止活性炭出水中浊度小幅升高的问题。另外 。

This paper described the process of advanced water treatment and its effect at Kunijima water purification plant in Osaka. By testing and analyzing conclusion was obtained that using Ozone-BAC advanced water treatment could remove the organic substances of middle molecular weight(<3000D), reduce the organic matters, such as DOC, Euv. But the turbidity of water after activated carbon treatment would increase a little. Ozone treatment before sand filtration was helpful to removel manganese and ammonia.
