摘要
针对猪场沼液脱氮难的问题,通过在UASB中实现同步厌氧氨氧化甲烷化反硝化达到脱氮除碳的目的。结果表明:中温条件下(31~35℃),UASB经过成功启动和90d的运行,逐步实现了同步厌氧氨氧化甲烷化反硝化,COD去除率为80%.90%,NO2-N去除率为90%以上,总氮去除率为50%-60%,氨氮去除率为8%~24%。
According to the difficulty of hogpen biogas slurry denitrogenation,simultaneous anaerobic ammonium oxidation,methanogenesis and denitrification have been conducted in a UASB reactor to achieve the purpose of denitrogenation and decarbonization. The results indicate that under medium temperature (31-35℃ )the UASB reactor is started-up successfully and operated at 90 d and the anaerobic ammonium oxidation, methanogensis and denitrification processes are realized simultaneously and gradually. The COD removal rate is 80%-90%, the NO2-N removal rate is above 90%, the TN removal rate is 50%-60%, and the ammonia-nitrogen removal rate is 8%-24%.
