| 摘 要： | 研究了一种可加速垃圾填埋场好氧稳定化进程的生物强化技术。实验对比了A、B、C 3种填埋方式,A、B为好氧填埋,C为厌氧填埋;A中接种高温复合菌剂,B、C中不接种菌剂。实验周期为20 d。研究发现:高温菌剂的投加起到了多重作用:增强了微生物的活动,导致A中的温度显著升高,最高可达72℃,且50℃以上的高温期达14 d,而B仅在45℃维持3 d,C则基本处于常温;加速了垃圾堆体的降解与稳定化进程,至实验结束,A中可生物降解有机质含量(BDM)去除率达51.2%,明显高于B、C中的BDM去除率(31.1%和39.4%);加速了堆体中含氮物质的降解与转化,减少了垃圾浸出液中氨氮的累积;加速了堆体的沉降,A中垃圾堆体沉降高度达10 cm,远大于B、C堆体的沉降高度(4 cm和2.5 cm)。

| Abstract: | The stabilization of municipal waste landfills often requires a long treatment period.To address this problem, a bioaugmentation method was proposed to accelerate landfill stabilization.Three types of landfills, namely, an aerobic bioreactor A with added microbial bioreagents, an anaerobic bioreactor B, and an anaerobic bioreactor C without any added microbial bioreagents.The experiment was conducted for 20 days.It was found that the addition of the microbial bioreagents significantly enhanced the microbial activity in aerobic bioreactor A, where a maximum temperature of 72℃ was observed and a high temperature (above 50℃) was maintained for 14 days.In contrast, the temperature in bioreactor B was maintained at only 45℃ for 3 days, and bioreactor C remained at the normal room temperature.The addition of the microbial bioreagents accelerated the nitrogen biotransformation of the municipal waste.The removal of biodegradable matter (BDM) achieved in bioreactor A was 51.2%, which was considerably higher than that in reactors B and C (only 31.1% and 39.4%, respectively).Moreover, the addition of the microbial bioreagents promoted the settlement of the waste;the settlement height in bioreactor A reached 10 cm, which was much higher than that in bioreactors B and C (4 and 2.5 cm, respectively). |
