| 摘 要： | 论文对桉木化学浆漂白废水的污染负荷及其超滤处理特性进行了研究。结果表明，ＣＥＨ三段漂白废水的主要污染来自Ｃ、Ｅ两段、占总负荷的８０％左右，其中色度主要来自Ｅ段废水，用木试验的ＰＳ膜进行超滤处理后，漂白废水的各项指标除ＢＯＤ５达到国家二级排放标准外，其余指标均达一级排放标准。

| Abstract: | The pollution loadings of effluents from C-E-H bleaching sequences of Eucalyptus kraft pulp were investigated respectively, and the characteristics of ultrafiltration treatment of the effluents were studied.Results obtained showed that the main pollutants of the bleaching effluents were from C-stage and E-stage spent liquor, by means of ultrafiltration with polysulphone membrane (COMW-3000), the rejection of ss and colour determined as about 100%, and BOD5 as 64. 3%. CODcr as 85. 1%, TOCl as 71. 3%, the permeate of ultrafiltration was permitted to be put out by the NDSWP for paper industry.It was concluded, therefore, that ultrafilter system can be used for bleaching effluent treatment and removals pollutants effectively. |
