Research on the response law of PAC-TMF coupling process for treating electroplating tin wastewater
The PAC-TMF coupling process was used to treat electroplating tin wastewater in an electronics factory,and the important factors affecting the operation of PAC-TMF were analyzed.On the basis of single factor,Box-Behnken combined design method is used to establish a mathe-matical model to optimize the operating conditions.The results show that the effect of the coupling process on Sn2+removal is greater than that on COD removal.When PAC dosage is 290 mg/L,crossflow velocity is 3.5 m/s,and concentration ratio of produced water is 1∶25,the removal effect of COD and Sn2+is better,which is 80.7％and 89.1％,respectively.The experimental data are in good agreement with the prediction model,which could guide the actual production.
