摘要
针对目前非正规垃圾填埋场采用的传统原位好氧稳定化技术稳定时间长、效率低的问题,采用原位生物强化好氧稳定化技术,在温州市某非正规垃圾填埋场治理中进行中试应用,并与传统好氧稳定化技术治理效果进行对比试验。研究表明:原位生物强化好氧稳定化技术可加速有机垃圾的生物降解,平均沉降量较好氧稳定化处理高54%;有机质质量分数较好氧稳定化处理低33.8%,提前5个月降低至有机质质量分数的修复目标值16%以下;填埋气体CH4体积分数降低至1.5%左右,较好氧稳定化处理低28.6%,且稳定时间缩短了5个月;渗滤液COD值较好氧稳定化处理低32.8%,BOD值较好氧稳定化处理高47.5%;氨氮质量浓度较好氧稳定化处理低32.7%,原位生物强化好氧稳定化技术的成功运行,为填埋场的快速稳定化提供新的思路与技术手段。
In order to solve the problems of long stabilization time and low efficiency of the traditional in-situ aerobic stabilization technology used in informal landfill,the in-situ biological enhanced aerobic stabilization technology was used in a pilot-scale application of an informal landfill in Wenzhou,and the treatment effect was compared with that of the traditional aerobic stabilization technology.The results showed that in-situ bioenhanced aerobic stabilization technology can accelerate the biodegradation of organic waste,and the average settlement was 54%higher than that of aerobic stabilization treatment.The mass fraction of organic matter was 33.8%lower than that of aerobic stabilization treatment,and it was reduced to below 16%of the remediation target value of organic matter five months in advance.The volume fraction of CH_(4)in landfill gas decreased to about 1.5%,which was 28.6%lower than that in aerobic stabilization treatment,and the stabilization time was shortened by 5 months.The COD value of leachate was 32.8%lower than that of aerobic stabilization treatment,and the BOD value was 47.5%higher than that of aerobic stabilization treatment.The mass concentration of ammonia nitrogen was 32.7%lower than that of aerobic stabilization treatment.The successful operation of insitu biological enhanced aerobic stabilization technology provides new ideas and technical means for the rapid stabilization of landfill.
