    摘要: Fe/C微电解法是以金属腐蚀的原理处理垃圾渗滤液的一种高级氧化技术,通过铁屑在渗滤液中同Cu、C、N等物质发生发应,产生氧化还原反应,形成絮凝物质从渗滤液中分离。在厌氧出水经Fe/C微电解进一步提高垃圾渗滤液可生化性的研究中,控制反应在酸性条件下进行,pH调节在5.0左右,Fe/C比(质量比)为1:1,调节搅拌转数为150 r/min,反应时间为60 min,出水的BOD5/CODCr(B/C)可达到0.3~0.4。Fe/C微电解法处理垃圾渗滤液,其B/C平均提高到0.365,平均净提高0.292,可生化性大大增强,有利于后续生物处理的进行。 Fe/C micro electrolysis is an advanced oxidation technology based on the principle of metal corrosion landfill leachate , through the iron should be reacted with Cu, C, N material in the leachate, oxidation-reduction reaction, and form the flocculating substance isolated from landfill leachate. Studying on improving landfill leachate biodegradability of the anaerobic effluent by Fe/C micro electrolytic, controlling the reaction under acidic conditions, the pH is about 5.0, the Fe/C ratio (mass ratio) is 1:1, the reaction time is 60 min, BOD5/CODCr (B/C) can reach 0.3 to 0.4 at last. Fe/C micro electrolysis deal with Landfill Leachate, its B/C reaches 0.365, the average net increases 0.292, its biodegradability can be greatly enhanced and it is conducive to the conduct of the subsequent biological treatment.
