摘要
以三维电极氧化与UASB+BAF组合工艺进行渗沥液降解试验,研究发现:以电压20V、pH5.3～5.5、极距4mm的电解条件降解渗沥液处理效果最佳;且出水COD、色度的去除率分别可达98.5%、98.1%。结果表明,采取该组合工艺能有效去除渗沥液中难降解有机物,出水可达到GB16889—1997的二级排放标准。
The experiment of leachate degradation was carried out by using the combined process of three-dimensional electrode oxidation and upflow anaerobic sludge blanket （UASB） add biological aerated filter （BAF）. The study showed the effect of leachate treatment was best under the electrolytic conditions that voltage was 20 V, pH was from 5. 3 to 5. 5, and pole pitch was 4 mm. The removal rate of effluent COD and chroma could be up to 98. 5% and 98. 1% respectively. The results showed that using this combined process could effectively remove refractory organic pollutants from leaehate, and the effluent could meet the secondary discharged standard of GB 16889-1997.
