摘要
以实际黑臭水体为样本,通过响应曲面(RSM)优化混凝法处理黑臭水体的操作参数,利用BBD设计原理,设计响应曲面17组实验方案,结果表明:三因素对COD去除率作用效果先后顺序为:PAC>PAM>pH,PAC投加量为109.85 mg/L,PAM投加量为1.17 mg/L,pH值为6.84时,此时最大的COD去除率预测值为60.30%。随后在此优化工艺参数条件下,进行5组平行实验,得到COD去除率的平均值为57.14%,与预测值的相对偏差为3.16%,模型得到验证。
Taking actual black and odorous water as samples,the operating parameters of coagulation method for treating black and odorous water were optimized by response surface methodology(RSM),Based on the BBD design principle,17 experimental schemes of response surface were designed,The results showed that the order of the effects of three factors on COD removal rate was PAC>PAM>pH,When the dosage of PAC was 109.85 mg/L,the dosage of PAM was 1.17 mg/L,and the pH value was 6.84,the maximum COD removal rate predicted value was 60.30%.Then,under the optimized operating parameters,five groups of parallel experiments were conducted,and the average COD removal rate was 57.14%,with a relative deviation of 3.16%from the predicted value,which verified the model.
