Experiments are conducted on the effect of different types and different molecular structures of polymers on HPAM removal existed in solution or sewage. It is found out that only cationic polymer has a better removal effect of HPAM among the non-ion, amphoteric ion and hydrophobical cation polymers, especially the DMDAAC cationic polymer has an optimal result. The removal capacity to HPAM can be further improved by using appropriate molecular weight and cationic capacity and gas floatation technique.
