摘要
利用超滤的分离特性剖析制浆洗漂废水及其絮凝上清液的COD的分子量分布,以探讨、评价絮凝法处理此类废水所能达到的最佳COD去除效果。研究结果表明,洗漂废水中MW>10000与MW<3000的物质是COD值的主要组成部分,占76％;COD最佳去除效果为70.3％。
Relative molecular weight fractions of COD in the waste water were determined by UF technology, so as to estimate the maximum removal rate of COD with flocculation-treat-ment. It has been found that most of the COD in the water is associated with the fractions having molecular weight greater than 10000 or smaller than 3000; the maximum removal rate of COD is 71.3%.
