为了减轻我国华东以及华北平原长期受到秸秆焚烧所带来的雾霾问题，通过利用秸秆为原料制备活性炭，研究了改性秸秆活性炭对印染废水的净化和吸附作用，并对实验条件进行了优化。结果表明在pH值为3，吸附时间为120 min ，吸附容量为100 g/L时，改性秸秆活性炭对印染废水的色度的去除率可达到100％，CODCr的去除率可达到87．6％，表明了秸秆活性炭在印染废水的处理上是可行的，同时又可以减少秸秆的大量焚烧所带来的环境污染，从而实现了双赢。

To alleviate haze caused by burning straws in East China and North China Plains ,the modified activated carbon prepared by straw is used to treat dyeing wastewater .The influence of initial pH ,adsorption time ,adsorption capacity are discussed .The re-sults show that when the conditions are controlled ,initial pH=3 ,adsorption time is 120 minutes ,and adsorption capacity is 100g/L , COD and chroma removal rates respectively are 84 .6% and 100% .The study shows that using the modified activated carbon pre-pared by straw to treat dyeing wastewater can have a good performance ,and the straw as the raw material for preparation of activa-ted carbon ,can fully enhance efficiency in the use of straw and waste ,alleviate the environmental pollution caused by burning straw so as to realize a win-win effect .
