摘　　要：研究了高浓度黄姜废水的铁炭微电解 混凝工艺 ,结果表明 ,在进水pH 4 0、停留时间为 4 0min且有曝气条件下 ,COD去除率达到 6 4 70 % ,色度去除率为 72 2 2 % ,废水的BOD/COD值可由 0 2 9提高到 0 5 6 ,有利于废水的后续生化处理。Pretreatment of Dioscorea zingiberensis C. H. wright wastewater in high concentration by microelectrolysis reator was studied. Its COD removal rate is 64.70%, chroma removal rate is 72.22% and BOD/COD increases from 0.29 to 0.56 when pH of influent is 4.0, hydrolic retention time is 40 min and the aeration installment is running.
