Polyacrylamide, formaldehyde and carbamide or guanidine carbonate were used as raw materials, cationic polyacrylamide flocculants were synthesized with Mannich reaction, effects of technical conditions on rate of turbidity removal were investigated, and synthesis technics was optimized. Experimental results showed that the flocculation properties of the products prepared with Mannich were better than ones of blank experiments (polyacrylamide). In the same dosage of flocculants, consumption of polyacrylamide in the products was smaller than (or equal to) 1/10 of polyacrylamide (blank experiments), reducing flocculation cost greatly. In the real wastewater treatment of sugar factories with the prepared products under optimum conditions, the turbidity removal rates was approaching to 90% or greater than 90% showing flocculation effectiveness was better. In addition, the wastewater of sugar factories was treated with prepared products and the removal of COD was 10~30%, which showed that using flocculating agents could reach the purposes of wastewater pretreatment.
