制革废水处理工程设计与效益分析

Design for Treatment Engineering and Effect Analysis of The Tennery Wastwater

介绍日排放量为1200m3的制革废水处理工程实例，文中详实地阐述了以活性污泥法为主体的生化处理工艺对废水中污染物的去除作用，并确定主要处理设施设计参数。经过一年多的实际运行，运行状况稳定，废水中COD去除率为80.8％，SS去除率为89．4％，Cr6＋去除率为92．5％，Cr总去除率为96.4％。

This article introduces the instance of the annery waster handing processs, which gives out wastewater for 1200m3 everday .It makes a careful description for the handing function of chetnisry treameut whose main section is sludge banding process and the settlement the main design parameter.The process had done a wonderful job when it was run for one year in practice work.As a result, the deducting rates of COD.SS.Cr3+ and C reach 80% 89.6and 96.4%.
