将聚合氯化铝(PAC)和羧甲基壳聚糖(MCM)以及二者复合物用于净化海水,对它们的絮凝效果进行研究。研究结果表明:(1)当聚合氯化铝投加量为88mg/L,pH范围为6.5~7.5时,无机絮凝剂对海水的净化效果最佳,对浊度和COD的去除率分别为75.36%和88.33% (2)当羧甲基壳聚糖投加量为200mg/L,pH为6~7左右时,有机絮凝剂的絮凝效果最好,对浊度和COD的去除率分别为53.84%和65%;(3)当无机/有机在配比为3:1、羧甲基壳聚糖的投加量为30g/L聚合氯化铝投加量为88g/L时复合的效果好,对浊度和COD的去除率分别为89.06%和96.67% ;(4)羧甲基壳聚糖与聚合氯化铝的复合絮凝效果优于羧甲基壳聚糖和聚合氯化铝单独使用的。

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.
