| 摘 要： | 采用响应面分析法对聚合氯化铝(PAC)与污泥生产的微生物絮凝剂复配处理涂料废水的过程进行了优化,设定的响应值为COD和色度去除率。实验分别拟合了关于COD去除率和色度去除率的二次模型,根据响应值的分布情况,确定涂料废水的最佳絮凝条件为微生物絮凝剂浓度47 mg/L,PAC浓度39 mg/L,pH为8.2,CaCl2浓度0.38 g/L,搅拌速度210 r/min。最佳絮凝条件下,微生物絮凝剂对涂料废水中COD和色度的去除率分别达到77.6%和68.9%。

| Abstract: | Response surface methodology was applied to optimize the composite of PAC and bioflocculant in the treatment of coating wastewater.COD and color removal rates were settled as the target responses.It was found that the optimal flocculating conditions for coating wastewater treatment were bioflocculant content of 47 mg/L,PAC dose of 39 mg/L,CaCl2 content of 0.38 g/L,pH of 8.2 and agitation speed of 210 r/min.The removal rates of COD and color reached 77.6% and 68.9%,respectively,under the optimal flocculating conditions. |
