摘　　要：生活垃圾填埋场渗沥液是一种成分复杂的高浓度有机废水,本文通过对某老龄生活垃圾填埋场渗沥液处理工程实例的分析,浅析了生化选用A/O工艺时,在满足排放要求的前提下,使用前置反硝化和后置反硝化的效果对比,同时分析了处理生化段的运行成本,后置反硝化比前置反硝化在药剂使用量上更为节省,其中葡萄糖节省约25%~30%,碳酸钠节省约5%~8%,氢氧化钠节省约5%~6%,总体运营药剂成本减少约30%。Domestic waste landfill leachate is a kind of organic wastewater with complex composition and high concentration.Based on the analysis of the leachate treatment project of an elderly household waste landfill,this paper analyzes the comparison of the effect of pre-denitrification and post-denitrification when the biochemical A/O process is selected,under the premise of meeting the discharge requirements,and analyzes the operation cost of the biochemical treatment section.The post-denitrification is more economical than the pre-denitrification in the amount of agents.Among them,the carbon source is saved about 25%~30%,sodium carbonate is saved about 5%~8%,sodium hydroxide is saved about 5%~6%,and the overall operating pharmaceutical cost is reduced about 30%.
