褐煤活性炭吸附处理焦化废水

研究褐煤活性炭吸附处理焦化废水的性能，为褐煤活性炭用于废水处理提供理论依据和技术指导。以河南某气化厂的焦化废水为吸附原水，进行褐煤活性炭对酚吸附性能的静态和动态实验。静态实验表明，褐煤活性炭对酚的吸附性能符合弗兰德里希（Freundlich）吸附方程式。在室温条件下，对于150 mL焦化废水，当活性炭的用量为10 g，吸附反应时间为1 h，酚的去除率可达92%以上。动态实验研究表明，当进水酚浓度为3 800 mg/L，吸附1.5 h，活性炭的吸附容量可达21.38 mg/g。水处理的实验研究表明，利用褐煤制备的活性炭，对焦化废水具有良好的处理效果。

Treatment of coke plant wastewater with lignite activated carbon

The adsorption performance of lignite activated carbon in coke plant wastewater was studied to provide theoretical basis and technique guidance for wastewater treatment by using lignite activated carbon. The static and dynamic adsorption experiments of lignite activated carbon for phenol in the coke plant wastewater from Henan were operated. The static adsorption experiments showed that the adsorption performance of lignite activated carbon for phenol in the coke plant wastewater was in keeping Freundlich adsorption epuation. When the condition of coke plant wastewater was 150 mL, activated carbon was 10 g, the adsorption time was 1 h and the removal rate of phenol was above 92%. The dynamic adsorption experiments showed that adsorption capacity of activated carbon was about 21.38 mg/g, when the condition of phenol concentration in the effluent water was 3 800 mg/L and the adsorption time was 1.5 h. These results indicate that lignite activated carbon is of good effect on adsorption in treating coke plant wastewater.
