以垃圾渗滤液为研究对象,研究UASB-除碳-一体化ANAMMOX工艺的除碳脱氮特性.结果表明：该工艺可实现高效除碳脱氮；在进水COD浓度6210~16365mg/L?TN浓度为990~2100mg/L时工艺出水COD浓度最低为655mg/L,出水TN浓度最低为39.9mg/L.进水中的可降解COD主要在UASB和除碳池中去除(分别为59%和31%),进入到一体化ANAMMOX池中的多为惰性有机物质；TN的去除在除碳池和一体化ANAMMOX池中进行,其中除碳池中TN去除量占工艺TN去除量的53%,主要通过同步硝化反硝化去除；ANAMMOX池中TN去除46%,主要通过AOB和AnAOB的协同作用实现.当除碳池出水含可降解有机物时,对后续一体化ANAMMOX池的自养脱氮抑制严重；充分降解除碳池中的可降解有机物是影响系统脱氮效率的关键因素.

Landfill leachate as the research object, the organics and nitrogen removal characteristics of UASB- decarbonize-integrated ANAMMOX process were studied. The results showed that: the process can achieve efficient carbon removal. With the influent COD concentration of 6210-16365mg/L, TN concentration of 990-2100mg/L, the effluent COD concentration was 655mg/L, the minimum effluent TN concentration was 39.9mg/L. Influent biodegradable COD were mainly removed in UASB and decarbonize tank. The removal efficiency was respectively 59% and 31%. while the left inert organic substances flowed into the integration ANAMMOX tank. TN removal took place in decarbonizes and integrated ANAMMOX tank. TN removal in decarbonize tank accounted for 53%, which was mainly through denitrification and simultaneous nitrification and denitrification removal. TN removal in ANAMMOX tank accounted for 46%, which was mainly through the synergy of AOB and AnAOB. When the effluent of decarbonize tank contained biodegradable organic matters, the autotrophic nitrogen removal process in the subsequent integration ANAMMOX tank was inhibited seriously. Full degradation of organics in decarbonize tank is the key factor for effective nitrogen removal in the whole system.
