垃圾渗滤液生化出水的脱色研究

分别采用脉冲电解法、混凝沉淀法、芬顿氧化法、高铁酸钾氧化法对垃圾渗滤液生化出水进行处理，考察了处理效果。结果表明：铁电极电解法和芬顿试剂氧化法均能脱除垃圾渗滤液的色度，去除有机物质。铁电极电解对色度的去除率可达98．4％，COD去除率可达84．4％；芬顿试剂氧化对色度的去除率可达99％，COD去除率可达85．8％。两种方法均能使出水达到排放标准。同时比较了各种处理方法的运行成本，在达到同样出水标准的前提下，铁电极电解运行成本远低于芬顿试剂氧化，为3．67元／t水，而芬顿试剂药剂成本为8．67元／t水。

Study on Decoloration Treatment of Landfill Leachate

Pulse Electrolysis,coagulating sedimentation,Fenton oxidation,potassium ferrate oxidation were employed for advanced treatment of landfill leachate after secondary biochemical treatment and the treatment effect was investigated.The results showed that both iron electrode pulse electrolysis and Fenton oxidation can effectively remove the color and organic matter of landfill leachate.The color removal rate was 98.4% and the COD removal efficiency was 84.4% by iron electrode pulse electrolysis method.The color...
