垃圾渗滤液配水对UASB-ANAMMOX反应器进行二次启动的研究

通过温度和进水控制对UASB-ANAMMOX反应器内的ANAMMOX菌的反应活性进行充分抑制后，采用垃圾渗滤液配水来进行二次启动.结果表明,二次启动的时间相对较快，在第21 d的 NH^＋₄-N的去除率就可以达到96 .17%，NO^-_２-Ｎ的去除率达到86 .77%；由于反硝化的协同作用降低使得COD的去除率有下降的趋势，平均去除量只有60 mg/Ｌ； 反应启动过程中的平均三氮比即去除的NH^＋₄-N∶去除的NO^-_２-Ｎ∶生成的NO^-_３-Ｎ=1∶0 .75∶0 .26； 反应成功进行二次启动后的平均三氮比即去除的NH^＋₄-N∶去除的NO^-_２-Ｎ∶生成的NO^-_３-Ｎ=1∶0 .95∶0 .26，三氮比中的亚硝氮去除比率较大幅度上升.

Research of the Second Start-up in USAB-ANAMMOX Reactor with Landfill Leachate

The second start-up of anaerobic ammonium oxidation (ANAMMOX) process with landfill leachate was investigated. It works after the ANAMMOX bacteria in the UASB-ANAMMOX reactor have been fully restrained by temperature and influent. The results reveal that the second start-up was faster, and the removal of NH4(+) -N and NO2(-) -N was up to 96.17% and 86.77% on the 21th day, respectively. The decrease of the synergetic mechanism of denitrification with ANAMMOX result in a declining trend of the removal of COD and the average quantity of removal was only 60 mg/L. The average ratio of removed ammonia , removed nitrite and produced nitrate was 1:0.75 : 0.26 in the second start-up process, and it was 1:0.95 : 0.26 at the stable stage of second start-up of ANAMMOX process. The removal of nitrite in the Three-Nitrogen-Compounds-Ratio has raised significantly.
