自然通风型多级矿化垃圾生物反应床处理渗滤液的小试研究

Various type of bioreactors constructed by the widespread mineralized refuse can be utilized to treat landfill leachate, and this new technique has the characteristics of easier operation, higher efficiency, lower energy consumption and construction cost etc., which suits the current environmental pollution situation and economic development status well. In this article, laboratory experiments are carried out on leachate treatment by natural-ventilation-type multistage mineralized refuse bioreactors, which draws conclusions as: when the attenuation period completes, under the conditions of leachate loading as 3.75L/m3 and interval leachate distribution period as 8h, the original leachate with COD and NH3-N concentration are 16800mg/L, 2128mg/L respectively, can be cut down to 202mg/L and 18mg/L by the five-stage mineralized refuse bioreactors, which values approach to National Level Ⅱ Wastewater Discharge Standard.
