| 摘 要： | 焦化废水是属有毒有害、难降解的有机废水,常规的生物处理工艺对其去除效果不甚理想,从而导致出水中难降解污染物含量较高,COD和NH3-N不能达标。论文针对焦化废水的水质特点,采用离子膜电解技术进行预处理。对焦化废水中主要污染物苯酚降解效果的几种因素进行了研究,得出了苯酚降解的最佳工艺条件并在此工艺参数下,对模拟焦化废水电解2.5h,苯酚、COD的去除率分别为84%,45%,氨氮去除率和回收率别为99.5%和96.5%,总能耗27kwh/m3,可以为后续生化处理大大减轻负担,采用该方法作为焦化废水的预处理手段比较经济合理。

| Abstract: | As coke plant effluent is considered recalcitrant wastewater,ion exchange membrane electrolysis method is used as a pretreatment measure to enhance the removal of COD and NH3-N. This paper focused on phenol,the main component of pollutants in coking wastewater and the optimal operating parameters were studied with a bench scale experimental installation. Result of treatment on the effluent of simulated coking wastewater indicated that ion exchange membrane electrolysis could remove phenol and COD at the rem... |
