沸石联合生物作用处理焦化废水的研究

Research of coking wastewater treatment with zeolite and biological combined processes

利用沸石对氨氮的强选择性交换,联合生物作用处理焦化废水。实验结果表明,该技术应用于活性污泥法、SBR工艺和A-A-O工艺中,能使焦化废水COD由进水平均800mg/L分别降至305mg/L、221mg/L和185mg/L,氨氮由进水平均45mg/L分别降至9.7mg/L、14mg/L和13.3mg/L。

Using zeolite and biological processes for treating coking wastewater was conducted. The result shows that when the processes are used to the activated sludge process, SBR process and A/A/O process, they can reduce the COD of 800 mg/L to 305 mg/L, 221 mg/L and 185 mg/L respectively and can also reduce the influent of NH3 - N from 45 mg/L to 9.7 mg/L, 14 mg/L and 13.3 mg/L respectively.
