| 摘 要： | 分别采用溶解性葡萄糖和颗粒性淀粉作为配水中的有机物,考察了混凝(烧杯试验)及造拉流化床时有机物的去除特性.研究表明,对于溶解性有机物(COD)而言,混凝对其去除效果非常有限,去除率仅为13.3% ,而大部分的颗粒性有机物可通过混凝作用去除;造粒流化床时溶解性有机物(COD)的去除率高达97.8% ,远远高于混凝及强化一级处理(CEPT)的.由于颗粒的形成,使得造粒流化床所去除的污染物不仅包括混凝可沉淀和可混凝但不可沉淀两部分,甚至还去除了相当一部分不可混凝的污染物,这是造粒流化床去除效率较高的原因.另外,颗粒的形成对于去除溶解性有机物的强化作用要明显高于对颗粒性有机物的.

| Abstract: | Using soluble glucose and particulate starch as organic matters in the feeding water,the contaminant removal efficiency was investigated in jar test and the fluidized pellet bed reactor.Only a fraction,i.e.13.3%,of soluble organic matters can be removed by coagulation;however,most particulate organic matters are removed in the jar test.In the fluidized pellet bed reactor,97.8% of soluble COD is removed,and the result is better than that in the jar test or chemical enhanced primary treatment(CEPT).The fluidi... |
