摘要
研究以开发低碳高氨氮质量浓度的老龄化垃圾渗滤液自养脱氮技术为目标,探讨高NH3-N质量浓度对其短程硝化效能的影响。结果表明,在温度为30℃,DO质量浓度为2.5mg.L-1,进水pH为8.0,NH3-N负荷为3.0kg.m-3.d-1的条件下,SBBR反应器短程硝化能承受的进水NH3-N质量浓度为3000mg.L-1,相应FA抑制质量浓度为179.56mg.L-1,系统的NH3-N去除率为56.7%。
The autotrophic nitrogen removal process was developed, which was applied to treat aging landfill leachate typical with a high concentration of the arnmaonia-nitrogen and a low concentration of carbon resource. Influence of ammonia-nitrogen concentration on shortcut nitrification efficiency was studied in this paper. Experimental results show that under temperature of 30 ℃, DO of 2.5 mg·L^-1, influent pH of 8 and nitrogen loading of 3.0 kg·m^-3·d^-1, the influent amnaonia-nitrogen concentration which the shortcut nitrification process in SBSR could hear is 3 000 mg·L^-1, with corresponding FA inhibition concentration of 179.56 mg· L^-1, and the removal efficiency of ammonia-nitrogen in this system achieves 56.7%.
