摘　　要：使用新型高效的絮凝剂 MF,对制革废水进行絮凝吸附、CO2 曝气、催化氧化回用处理试验 ,确定了絮凝剂 MF的最佳使用条件、催化氧化时间和氧化剂用量。结果表明 ,制革废水经工艺处理后 ,对废水中主要污染物 CODCr、S2 - 、Cr3+、SS、色度的去除率分别达到 78.9%、97.5%、95.5%、91 .4 %、96.5%。处理后的废水基本达到鞣铬工艺用水要求和国家《污水综合排放标准》( GB8978-1 996)限定的二级标准。An experiment with the tanning wastewater treatment through flucculation, CO 2 aeration and catalytic oxidation was made to determine the optimal conditions for using the flucculant MF, the catalytic oxidation duration and the oxidant consumption. It is shown from the test results that the removal rates for the main pollutants COD, S 2- ,Cr 3+ and SS in the wastewater are 78.9 %,97.5 %,95.5 % and 91.4 %, respectively. The treated effluent basically meets the standards for the water used for tanning process and the national standards for the discharged water of second category.
