| 摘 要： | 用改性壳聚糖复配无机絮凝剂FeCl3处理微污染水。结果表明:用改性壳聚糖替代壳聚糖,在用量节省约50%时,显著提高了浊度和有机物的去除效果。与单独使用壳聚糖相比,改性壳聚糖、FeCl3、改性壳聚糖复配FeCl3处理微污染水,UV254去除率分别从26%、42.4%、47%提高到68%,浊度去除率分别从52.6%、83.7%、79.7%提高到92.6%。在pH=7,沉降时间10 min等最佳条件下,改性壳聚糖复配FeCl3强化混凝处理微污染水效果优于聚丙烯酰胺。

| Abstract: | Treating of slightly-polluted water with modified chitosan remixed with inorganic flocculant FeCl3 was carried out.The experimental results showed that modified chitosan in half amount of chitosan had better removal effect for turbidity and organics than chitosan.UV254 removal rate by chitosan,modified chitosan,inorganic flocculant FeCl3 modified chitosan remixed with inorganic flocculant FeCl3 was respectively from 26%,42.4%,47% up to 68%,and turbidity removal rate by them was respectively from 52.57%,83.67%,79.7% up to 92.56%.On optimal operation of pH 7 and settling time 10 min,enhanced-coagulation treatment effect of slightly-polluted water by modified chitosan remixed with inorganic flocculant FeCl3 was superior to that by polyacrylamide. |
