垃圾渗滤液烟气脱硫体系的实验研究

Experimental study on the system of flue gas wet desulfurization with landfill leachate

利用垃圾渗滤液中较高的碱度吸收二氧化硫是垃圾渗滤液湿法烟气脱硫工艺的第一阶段。试验证明 ,垃圾渗滤液可高效吸收二氧化硫 (去除率可达 90 %以上 ) ;同时垃圾渗滤液中氨氮浓度由 133mmol L降至 78mmol L。

It is the first stage of biological FGD technology with leachate to absorb SO 2 by the alkalinity produced in the process of rabbish biodegrdation while stripping ammonia from leachate by flue gas. The experiment illustrated that leachate can absorb SO 2 (the removal rate can be above 90%) with high efficiency; and the concentration of ammonia_nitrogen in the leachate has been reduced from 133 mmol/L to 78 mmol/L .The result of experiment proved the mutal benefit of the system of flue gas wet desulfurization with landfill leachate.
