【摘要】 利用脱乙酰壳多糖处理林可霉素生产废水，研究了絮凝剂用量、静置时间、ｐＨ值、温度及活性炭对降低化学需氧量（ＣＯＤ）的影响．结果表明，在实验条件下，脱乙酰壳多糖具有较高的降低ＣＯＤ的能力，并适合于处理酸性和中性废水．更多还原

【Abstract】 Lincomycin manufacturing waste water was treated with chitosan. The influences of amount of flocculant, standing time, pH value, temperature and activated carbon on the reduction of COD are mainly discussed. The higher ability was found when chitosan was used to reduce COD in the experiment condition. Results show that the flocculant is suitable for the treatment of acidic and neutral waste water.更多还原
