摘    要:为了推动厌氧氨氧化(ANAMMOX)在城市污水处理中的工程化应用,在常温条件下,采用生物滤池反应器,分别考察了硝酸盐、磷酸盐、氨盐和亚硝酸盐对ANAMMOX运行效能的影响.试验结果表明:当进水NO3--N质量浓度提高至约500mg/L时,不会对总氮去除负荷产生明显的影响;而当进水总磷质量浓度大于10mg/L时,总氮去除负荷下降明显,停止投加磷酸盐后,总氮去除负荷可以得到恢复;适当提高NH4+-N和NO2--N的浓度,有利于总氮去除负荷的提高.可见常温条件下,硝酸盐对于低氨氮城市污水ANAMMOX生物滤池的脱氮活性基本不存在影响.而正磷酸盐浓度负荷对于ANAMMOX反应具有一定的影响,且进水磷酸盐浓度的提高对常温低氨氮城市污水ANAMMOX反应存在可逆性抑制作用.

关 键 词:厌氧氨氧化  生物滤池  城市污水  生物脱氮  常温

Abstract:In order to promote the engineering applications of anaerobic ammonium oxidation (ANAMMOX) for urban sewage treatment,the impact of nitrate,phosphate,ammonia and nitrite on the running performance of ANAMMOX biofilter reactor at room temperature was investigated respectively. Experimental results show that there is no significant impact on the TN removal load when the influent NO 3--N concentration is increased to about 500 mg/L. However,the TN removal load will drop obviously when the infulent TP concentration is higher than 10 mg/L,which can be restored after stopping dosing phosphate. Appropriately increasing the concentration of NH 4+-N and NO 2--N is beneficial to the improvement of TN removal load. At room temperature conditions,nitrate basically has no effect on the ANAMMOX biofilter for municipal wastewater with low ammonia. But for phosphate,it has a certain impact on the activity of ANAMMOX,and the improvement of the influent phosphate concentration has a reversible inhibition for ANAMMOX reaction in the urban sewage with low ammonia.
Keywords:ANAMMOX  biofilter  municipal wastewater  biological nitrogen removal  room temperature
