Abstract
The inorganic-organic composite flocculants PAC-CTS were prepared and used for treatment of municipal sewage and waste water of heavy metal.It showed that the composite flocculants were better than primary inorganic and organic flocculants.For municipal sewage more than 94% chromaticity,99% turbidity and 68% COD were wiped off by 80 mg/L dosage of the flocculants with 20% weight fraction chitosan in the composite flocculant at about 8 pH value;And for waste water containing metal,the rate of removing metal Cu~(2+) and Pb~(2+) reached above 85% and 73% respectively at about 8 pH and 300 g/kg CTS when the dosages were 4 mg/L and 5 mg/L respectively.
