摘要
采用絮凝—Cl O2 氧化法对造纸废水进行处理 ,筛选出最佳的絮凝条件及氧化条件 .实验结果表明 ,该法可使原水 CODcr从 1 4 0 0 mg/L降至小于 70 mg/L.废水CODcr与色度去除率分别大于 95%和 97% ,出水达到排放标准 .该方法具有去除率高、设备简单、占地面积小、操作方便。
The coagulation\|ClO\-2 oxidation process is used in treating papermaking wasterwater and the best conditions of coagulation and of oxidation were selected. The result of experiment shows that by using this process, COD\-\{cr\} of wasterwater could be reduced from about 1 400 mg/L to 70 mg/L, and the removal rates of COD\-\{cr\} and chromaticity are over 95% and 97% respectively.
