摘要
简介了污水脱氮等技术的进展;以深圳市下坪垃圾填埋场渗滤液为对象,在SBR设备中进行了渗滤液同步硝化反硝化的研究,分析了COD,DO,NH3 N对同步硝化 反硝化所产生的影响。结论表明,同步硝化 反硝化进行的程度与溶液中氨氮浓度呈反比关系,而与COD浓度及氨氮浓度的下降速度成正比。
The paper presents an overview of the progress in nitrogen removal from wastewater.Taking the Xiaping landfill leachate in Shenzhen city as the object,it has studied the process of simultaneous nitrification and denitrification of landfill leachate in the SBR reactorThe influences of COD, DO and NH3N on the nitrogen rernoval have been analyzed. The results show that an inverse relation exists between the degree of the simultaneous nitrification and denitrification process and the ammonia nitrogen thickness of aqua. There are direct ratios between the degree of the process and the concentration of COD as well as the descending rate of ammonia nitrogen thickness
