摘　　要：粉煤灰经过废硫酸改性处理后吸附能力大大提高,用改性粉煤灰对生化后的利福平废水进行了脱色试验,实验考察了废硫酸的投加量、pH值、粉煤灰的粒径对色度去除率的影响,并对脱色机理进行了分析。粉煤灰改性后应用于利福平废水处理中达到以废治废,具有一定的经济意义。The sorption capacity of coal ash will increase greatly when modified by waste sulfuric acid.Modified coal ash was applied to remove chromaticity from Rifampicin wastewater removed by means of biological chemistry.The factors of waste sulfuric acid dosage,pH value and coal ash particle diameter to chromaticity removal rate were examed,and the mechanism of decoloration is analyzed.Applying modified coal ash to the treatment of Rifampicin wastewater has some advantages such as using rubbish to harness rubbish...
