生物接触氧化处理大治河原水的试运行介绍

Summary of Full-Scale Pretreatment of Dazhi River Raw Water by a Biological Contact Oxidation Process

就上海市惠南水厂生物预处理工程的处理效果及对后序常规处理的影响进行了生产性试运行研究。运行结果表明 ,经生物接触氧化工艺 ,NH3 -N ,色度 ,CODMn,浊度 ,铁 ,锰分别去除78 7% ,2 4 13% ,12 36% ,64 4 3% ,4 8 64% ,69 3% ,对原水水质有明显的改善 ,可以较大地提高出厂水水质 ,并降低运行成本。

Effect of biological pretreatment on conventional water treatment process of Huinan Waterworks in Shanghai has been investigated. Experimental results showed that removal efficiency of NH 3-N, color, COD, turbidity, iron and manganese were 78 7%, 24 13%, 12 36% , 64 43% , 48 64 % and 69 3% respectively, suggesting that the raw water quality is improved through the biological pretreatment processes. The quality of output water was also promoted and the cost was reduced after the biological contact oxidation process had been used.
