| Poly aluminium chloride (PAC) and carboxymethyl chitosan (MCM) as well as the two complex were used to purify seawater, and their flocculation effects were also studied.The results showed that: (1) when the dosage of polyaluminium chloride and pH range were 88 mg/L and 6.5 ~ 6.5 respectively, the seawater purification effect with inorganic flocculant is the best, with turbidity and COD removal rate of 75.36% and 88.33% respectively. (2) when the carboxymethyl chitosan dose was 200 mg/L and pH was about 6 ~ 7, optimumflocculating effect was obtained by organic flocculants, with turbidity and COD removal rate of 53.84% and 65% respectively; (3) when the ratio of inorganic/organic was 3:1, with dosage of carboxymethyl chitosan and poly aluminium chloride of 30 g/L and 88 g/L respectively, the composite effect is good and the turbidity and COD removal rate reached 89.06% and 96.67% respectively;(4)the flocculating effect of carboxymethyl chitosan with polyaluminium chloride compound is better than that of carboxymethyl chitosan and polyaluminium chloride used alone. |
