浙江某废纸造纸企业生产废水经物化生化处理后，COD降至130mg／L，SS降至110mg／L，尚未达到国家新排放标准（GB3544—2008）。采用SPSS统计分析软件，在8种商品絮凝剂、助凝剂中优选出配方：2号聚合氯化铝1000mg／L＋3号阴离子聚丙烯酰胺1mg／L。PAC2用量500～1000mg／L，PAM3用量1～2mg／L都可使排放废水从CODl30mg／L进一步降低至COD＜80mg／L，达到了国家排放标准，吨水最低混凝药剂费用0．29元。应用SPSS软件优化了混凝剂筛选过程，提高了工作效率。

After biochemical treatment, the wastewater of a recycled paper mill in Zhejiang province could be achieved with COD 130mg/L and SS ll0mg/L. SPSS statistical analysis software was adopted to choose the optimum combination agents from 8 market flocculants. The optimal combination proved to be PAC2（1000mg/L）dnd PAM3 （lmg/L）. The coagulation process could reduce the effluent COD from 130mg/L to less than 80mg/L with PAC2 （500mg/L-1000mg/L）and PAM3 （lmg/L- 2mg/L） at the least cost of 0.29 yuan per ton, which not only meet the new discharge standard, but optimize the process of coagulant screening with higher efficiency.
