摘　　要：采用炭化秸秆与改性粉煤灰联合去除废水中COD。重点研究了秸秆炭化温度、粉煤灰改性条件以及二者配比对废水COD去除率的影响。结果表明,吸附温度40℃条件下,炭化的粉煤灰和氯化锌改性的粉煤灰在2∶1条件下混合,去除废水中COD性能较佳,COD去除率可以达到90%以上。Wastewater was treated by fly ash and wheat straw and the impact of absorption temperature, adsorption time, the mass ratio on the COD adsorption efficiency were investigated. Results showed that the adsorption effect of COD can reach 90 % under mass ratio was 2 ： 1 with wheat straw and fly after 20 rain at 40 degree.
