臭氧组合工艺去除黄浦江原水中有机物

Removal of Organic Matters in Huangpu River by Ozone-combined Process

采用预臭氧化—常规处理—后臭氧化—生物活性炭深度处理工艺对黄浦江原水进行了中试试验,研究结果表明该工艺对去除有机物方面有良好效果,CODMn、UV254、DOC、AOC的总体去除率分别是62.3%、91.8%、63.7%、27%。臭氧氧化不能彻底去除有机物,但通过活性炭的协调作用可将其有效去除。

The pilot-scale experiment was carried out by ozone-combined processes composed of preozonation-conventional treatment-O3-BAC advanced treatment. The removal rates were 62. 3% for CODMn,91.8% for UV254,63.7（1. State Key Laboratory of Pollution Control and Resource Reuse,Tongji University, Shanghai 200092,China; 2. Shanghai Municipal Waterworks Min Hang Co. Ltd, Shanghai 201100,China） for DOC and 27% for AOC. Ozonation cannot remove the organics completely, which are removed effectively with the assistance of biological activated carbon（BAC）.
