摘　　要：就使用柱层累托石材料对有机废水处理的实验研究进行讨论。采用累托石材料 ,在用量为 15kg/t时 ,加入用量为 5kg/t的还原剂FE ,废水中COD去除率达 70 %;如果再用累托石进行二次吸附 ,其COD去除率达 92 %,处理水COD值降为 96mg/L ,达到GB8978- 1996一级排放标准。同时实验了累托石的再生利用效果。Organic wastewater engenders serious pollution to environment. This paper deals with the experimentation of the wastewater disposal by using pillar-layered rectorite materials. With the application of rectorite material,the removing ratio of COD in wastewater attains 70% under the condition of rectorite material dosage of 15 kg/t and reductant FE dosage of 5 kg/t. If rectorite is applied for the second time to the adsorption,the removing ratio of COD in wastewater can be as high as 92%. The value of COD in treated water is diminished to 96 mg/L and accords with the first level criterion of draining in terms of GB8978-1996. Furthermore, the experiments of the effect of regenerated rectorite material are tried.
