改性粉煤灰去除硝基苯废水的研究

Study on the Removal of Chromaticity in Nitrobenzene Wastewater by Modified Coal Ash

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硝基苯废水进行了实验研究,实验考察了粉煤灰的投加量、pH值、吸附时间对硝基苯去除率的影响,并对机理进行了分析。粉煤灰改性后应用于硝基苯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 greatly increase when modified by waste sulfuric acid.Experiments are conducted to trest biochemical nitrobenzene wastewater by using modified coal ash, in which the influences tithe dosage, pH value, absoxption time on chromaticity removal are investigated and the mechanism is analyzed. The use of modified coal ash to treat nitrobenzene wastewater is of great economic significance, in which the rubbish is used to harness rubbish.
