摘要

以实际高氮晚期渗滤液为研究对象

应用缺氧/厌氧UASB-A/O组合工艺重点研究有机物和氮的去除特性

同时考察了A/O系统内短程硝化实现途径及稳定方法。试验结果表明

该生化系统可实现有机物和氮的同步、深度去除。在原液COD平均为6537 mg·L-1

NH+4-N为2021 mg·L-1的条件下

系统最终出水分别为300 mg·L-1和15.6 mg·L-1

去除率分别为95.4%和99.2%。UASB反应器的平均COD负荷为6.5 kg COD·m-3·d-1

去除速率为5.3 kg COD·m-3·d-1。在单一UASB反应器内

发生了缺氧反硝化和厌氧产甲烷的双重生化反应

UASB反应器内获得了几乎100%的反硝化率。通过高游离氨（FA）和游离亚硝酸（FNA）的协同作用

使A/O反应器实现并维持了稳定的短程硝化

通过99%以上的亚硝化率实现高效的氨氮去除。

Abstract

The treatment of real leachate from municipal landfill with high ammonia nitrogen(NH+4-N) content was studied by using a combined process of lab-scale anoxic/anaerobic up-flow anaerobic sludge bed (UASB)-A/O. The method for achieving and stabilizing partial nitrification in the A/O reactor was also investigated. Experimental results clearly showed that COD and nitrogen can be simultaneously deeply removed with this combined biological system

average COD and NH+4-N have been reduced from 6537 mg·L-1 and 2021 mg·L-1 in the raw leachate to 300 mg·L-1 and 15.6 mg·L-1

respectively. For the anoxic UASB reactor

the average organic loading rate reaches to 6.5 kg·m-3·d-1

and its average organic removal rate is 5.3 kg·m-3·d-1. The denitrification and methanogenesis are simultaneously conduced in the UASB reactor

and almost 100% denitrification has been achieved. A stable and long term partial nitrification have been realized by the cooperative effect of FA and FAN

the ammonia nitrogen has been removed through the highly effective partial nitrification with above 99% nitrite accumulation rate.
