电催化系统-电生物炭接触氧化床处理垃圾渗滤液

 提出了电催化系统(ECS)组合电生物炭接触氧化床(EBACOR)来处理垃圾渗滤液的方法.结果表明,ECS-EBACOR法诸多的影响因素中,对处理效率影响最大的是ECS的电活性催化填料组分.GC/MS分析结果表明,垃圾渗滤液中的64种有毒有机污染物经ECS处理后,大部分已被矿化成CO₂、H₂O或降解为小分子有机物.ECS-EBACOR现场运行试验结果还表明,当垃圾渗滤液废水中的COD和NH₃-N浓度分别在3000～5000mg/L以及1100～1780mg/L范围时,COD和NHs₃-N去除率均可超过90%.

The method of ECS-EBACOR for treating landfill leachate

In this paper, a method for treating landfill leachate by the electric catalysis system(ECS) and the electro-biological activated carbon oxidative reactor(EBACOR) has been proposed. The results indicate that the component of the electro-activated catalytic filler of the ECS has greatest influence on the treatment efficiency among all the affecting factors of ECS - EBACOR technique. The analytic results of GC/MS showed that most of the 64 toxic organic pollutants in the landfill leachate were degraded into small molecular organic compounds or were mineralized to CO2 and H2O by the ECS treatment. The results of the on-the-spot operation test with ECS -EBACOR also showed that more than 90% of the COD and NH3-N was removed when the concentration of COD and NH3-N of the landfill leachate were 3000~ 5000mg/L and 1100~1780 mg/L respectively.
