摘　　要：以酸性大红染料废水为研究对象,采用粉煤灰作为吸附剂,在不同条件下进行脱色研究,考虑粉煤灰的投加量、染料的浓度、染料溶液的p H、吸附时间等因素对脱色效果的影响。结果表明,该种粉煤灰对对酸性大红染料废水的脱色效果良好,吸附能力强,出水可以达到国标《纺织染整工业水污染物排放标准》(GB 4287-2012)的间接排放标准。The effects of fly ash dosage,dye concentration, pH of dye solution, adsorption time, and so on ,on the decolonization effect are studied by regarding acid red dye wastewater as the research object and using fly ash as the adsorbent in different conditions. The results show that the decolonization effect of the fly ash on the acid red dye wastewater is good, the adsorption capacity is strong and the effluent can reach the indirect emission standard of GB4487-2012.
