摘 要：
针对传统卫生填埋场(R1)、渗滤液直接回流填埋场(R2)和渗滤液污染物浓度高等问题,采用现场采样及室内分析测试方法,对两相型生物反应器填埋场系统(R3)进行了研究。结果表明,两相型生物反应器填埋场系统(R3)中,由于产酸细菌与产甲烷细菌分别在不同的装置中,因而解决了酸积累的中间产物抑制问题,加快了有机物的降解过程,同时使出水渗滤液的CODCr和NH3--N始终稳定在12000mg·L-1和500mg·L-1以下,为渗滤液的后续处理工艺提供了方便。

摘 要：
To deal with the high organic pollut ant of the traditional landfill(R1)and the lechate -recirculation -lan dfill system(R3),the two -phase bioreactor -landfil l system(R3)was studied through combining site s ampling and laboratory analysis.In the two -phase bioreactor -landfill system(R3),acid -producing bacteria and methane -producing bacteria had been found in two reactors separately that resolved t he problemof between products retarding action on acid accumulation and quickened the degradation of organic pollutant.The concentra tion of CODcr andNH 3- -N in leachate were both stably below12000mg ·L -1 and 500mg ·L -1 respectively in R3,which made the le achate aftertreatment easily.
