| 摘 要： | 本文引入了TbOD(总BOD)概念代替BOD，来作为渗滤液可生化性指标的一个间接量度，其主要目标是考察经电催化氧化技术对垃圾渗滤液进行预处理后，水质可生化性的变化情况．结果表明，电解时间以及电流密度对渗滤液可生化性的影响较为明显，电催化氧化技术能有效提高渗滤液水质的可生化性，TbOD／COD由原来的0．39上升到0.75，电催化氧化对NH3-N的去除效果明显，电解90min后，最终NH3-N去除率能够达到94．8％，有利于后续的生物法处理。

| Abstract: | An idea of TbOD(total BOD in stead of BOD) is used as an indirect measure for biodegradability index of leachate. Its main purpose is to investigate the changing conditions of biodegradability of water quality after pre-treatment of landfill leachate by electrocatalysis oxidation. The results showed that the effect of electrolysis time and current density on degradability of leachate is more obvious; electrocatalysis oxidation technique can improve the biodegradability of leachate effectively; when TbOD/COD rose from original 0.39 to 0.75,the effect of electrocatalysis oxidation on NH3-N removal was obvious; after electrolysis for 90min, the final removal rate of NH3-N could reach to 94.8%, being advantageous to follow-up treatment by biological method. |
