Application of Double Alkali PAM Cation in Wastewater Decalcification
The decalcification performance of double alkali PAM cation on wastewater was studied.In this experiment,after adjusting the pH of the wastewater to become basic,trisodium phosphate was added to make the decalcification rate of the precipitation clear liquid reach more than 50%,and then PAM cation was added to make the precipitation form filter mud to discharge the decalcification system.The results show that the effect of decalcification can be achieved by adding trisodium phosphate after adjusting the pH of the sewage,and the precipitation can be discharged by adding PAM cation,which is of great significance for the subsequent process to continue to treat the sewage waste liquid and reduce the risk of scaling.
