短程硝化反硝化+厌氧氨氮化+硫自养反硝化工艺处理老龄填埋场渗沥液中试工程设计

Pilot Project Design of Short-cut Nitrification and Denitrification+Anaerobic Ammonia Oxidation+Sulfur Autotrophic Denitrification Process for the Treatment of Aged Landfill Leachate

采用短程硝化反硝化+厌氧氨氧化+硫自养反硝化工艺用于老龄填埋场渗沥液,对佛山高明苗村白石坳垃圾卫生填埋场的垃圾渗沥液进行中试工程设计,设计处理规模12 m^(3)/d,出水水质达广东省地方标准《水污染排放限制》(DB44/26-2001)中第二时段一级标准与《生活垃圾填埋场污染控制标准》(GB 16889-2008)表2的较严值,解决传统生化工艺处理过程中的碳源投加量大、污泥产生量大等问题,为优化该场渗沥液处理工艺以及降低处理成本提供理论支持,也为同类项目提供参考。

This project adopts short-cut nitrification and denitrification+anaerobic ammonium nitrification+sulfur autotrophic denitrification process to carry out the pilot project design of the aged landfill leachate at the Baishi'ao Waste Sanitary Landfill in Gaoming Miao Village,Foshan,with a designed treatment scale of 12 m^(3)/d.The effluent water quality meets the second-period first-level standard in the local standard of Guangdong Province“Discharge Limits of Water Pollutants”(DB44/26-2001),and the stricter standard in Table 2 of the“Standard for Pollution Control on the Landfill Site for Domestic Waste”(GB 16889-2008).Fortunately,this design avoids a large amount of carbon source dosing requirements and sludge production in the traditional biochemical process,and provides theoretical support for optimizing the leachate treatment process and reducing treatment costs in this field,which provides a reference for similar projects.
