以稻秸(壳)为原料的多孔载体在污水处理中的应用

Application in sewage disposal of porous carrier taking rice straw(shell) as raw materials

通过实验证明,以稻秸为原料的活性炭结合稀土废渣材料对污水进行处理,可以有较高的COD去除率(进水COD 200 mg.L-1去除率可达70%)和细菌杀灭率(进水大肠菌落2.5×104个.L-1去除率可达90%),对污水的初级处理及农村生活污水的处理有积极的推动作用。

Proved through the experiment that, using activated charcoal taking the rice straw as the raw material which unions rare earth waste residue material to process the sewage, may have high COD removing rate （When enters water COD is 200 mg·L^-1, removing rate may reach 70% ） and the high sterilization rate （when enters water number of E. coli is 2.5 × 10^4·L^-1, removing rate may reach 90%）, has the positive function to sewage primary processing and village life sewage processing.
