摘要:UASB 皮应器预处理高浓度 NH4+ -N 废水,采用较低的C/ N ,降低后续处理的 NH4+ -N
进行短程硝化与皮硝化,经边 75 d 的实验得出, 20 - 30 "C , pH 僵 .- ,C/
- 4. 5. NH4+ -N 浓度在 500 mglL 左击,去除率达到 40% ,并且反应器运行稳足,可以作为对高浓度 NH4+ -N 废
水的预处理.

Abstract: The pretreatment of high concentration NH 4+ -N wastewater was carried out by UASB reactor and a lower C/N was used to re•
duce the NH 4+ 四 N load of the follow-up treatment. By using shortcut nitrificatior叫 enitrification in the reactor for 75 d experimental cy•
cles , the best control condition of reactor were obtained as follows: temperature was 20-30 "C ; pH was 7. 0-8. 0; C/N was 3. 5 -4. 5 ; the
concentration of NH 4+ -N was about 500 mglL. The re
