摘　　要：通过确定化学法制浆过程各工序废水量、特征污染物种类和浓度、存在状态,采用等标污染负荷法定量解析各工序、各特征污染物等标污染负荷与负荷比。结果表明,备料工序主要污染物是BOD、COD和悬浮物;蒸煮工序主要污染物是BOD和COD;洗涤筛选净化工序主要污染物是BOD和COD;CEH漂白工序主要污染物是二噁英;ECF漂白工序主要污染物是BOD、COD和悬浮物;TCF漂白工序主要污染物是BOD和COD;主要污染工序为蒸煮和漂白,两个工序累计等标污染负荷比达到90%以上。该研究结果可为造纸行业化学法制浆的水污染全过程控制提供科学、可靠的依据。By determining the amount of wastewater,the types and concentrations of characteristic pollutants,and the state of existence in each process of the chemical pulping process,the equal-standard pollution load method was used to quantitatively analyze the standard pollution load and load ratio of each process and each characteristic pollutant.The results showed that the main pollutants in the preparation process were BOD,COD and suspended solids;the main pollutants in the cooking process were BOD and COD;the main pollutants in the washing,screening and purification process were BOD and COD;the main pollutants in the CEH bleaching process were dioxins;the main pollutants in the ECF bleaching process were BOD,COD and suspended solids;the main pollutants in the TCF bleaching process were BOD and COD;the main polluting processes were cooking and bleaching,and the cumulative equivalent pollution load ratio of these two processes reached more than 90%.The research results could provide a scientific and reliable basis for the whole process control of water pollution in chemical pulping in the paper industry.
