亚硝化-厌氧氨氧化一体化反应器用于畜禽养殖废水深度处理的研究

Advanced Treatment Study of Livestock Poultry Wastewater with Sharon-anammox Integrative Reactor

利用自行设计的亚硝化-厌氧氨氧化一体化反应器,在常温（18-30℃）条件下,对某养猪场经生化处理后的二沉池出水进行深度处理。通过实验确定了一体化反应器的最佳HRT、DO值以及在此条件下养猪场废水处理效果。结果表明,一体化反应器对养猪场废水处理效果明显,基本达到排放要求。

The secondary sedimentation tank effluent a ft er the biochemical processing of livestock wastewater was advanced treated by the integrated anaerobic ammonium oxidation reactor,under the condition of room temperature（18 -30 ℃）. The optimum values of HRT and DO and the livestock wastewater treatment effects of the integrated reactor were determined by experiment. Result show that the effect of the integrated reactor for livestock wastewater treatment was obvious. While the average influent concentration of NH4^＋-N and TN were 159 mg/L and 200 mg/L respectively,the average effluent concentration of NH4^＋-N,TN and NO2^--N were 15 mg/L,58 mg/L and 6.27 mg/L respectively,which met the requirement of wastewater discharge.
