摘要
为了降低垃圾渗滤液中高浓度NH3-N对生物处理的影响,采用吹脱法预处理垃圾渗滤液中的NH3-N,对影响吹脱的因素进行了研究。试验结果表明:在最佳实验条件下,即pH=8.5,曝气强度为180m3/(m2·h),经24h吹脱,NH3-N去除率可达到55.6%,出水NH3-N不会对后续生物处理产生抑制。
To reduce the influence of high concentration NH3-N in landfill leachate to biological treatment, blow-off method was used to remove NH3 - N, and several influent factors were studied. The result showed that: at the optional conditions or: pH =8.5, aeration intensity is 180 m^3/(m^2 · h), the removal rate of NH3 -N was 55, 6% after 24 h blowing, and the effluent NH3 - N concentration could not limit biological treatment.
