臭氧—生物活性炭工艺去除水中有机微污染物

Study of trace organic pollutants removal from water by ozonation-biological activated carbon process

在臭氧接触反应柱中填装陶粒滤料 ,构成了臭氧—陶粒→生物活性炭饮用水深度净化流程 ,用该流程去除水中有机微污染物 ,CODMn去除率接近 4 0 % ,浊度和色度大大降低。色 -质联机分析结果表明 ,原水中有机物由 58种降至 30种 ,潜在有毒有害物质由1 3种减少到 4种。

The ceramic media was filled in that ozonation column.The technology process of O 3 ceramic biological activated carbon was used to advance water purification.The COD Mn removal efficiency of this process was nearly 40% and the turbidity and the colourity were greatly decreased.The numbers of the organic pollutants in the effluent were reduced from 58 to 30 by the process according to the GC MS analysis.
