The wastewater treatment for repulped papermaking plants using chitosan and its compasite chitosan as biosorbents is studied.
考察了pH值、壳聚糖用量、搅拌速率及静置时间等对COD去除率的影响,得出了最佳实验条件:pH值6 5～6 7,搅拌速率120r/min,静置时间12h,壳聚糖最佳用量为0 4g/L,在此条件下废水的COD去除率可达66%以上·壳聚糖处理效果明显优于无机混凝剂硫酸铝;将壳聚糖与硫酸铝进行配比制得复合净水剂处理再生造纸废水,可进一步提高COD的去除率,去除率可达到83%以上·该净水剂既可以有较高COD去除率,又可以避免二次污染,有较好的环保效果
