厌氧-准好氧型填埋的渗滤液实验研究

通过室内模拟试验，在渗滤液回灌的厌氧填埋柱基本进入稳定状态后，改用准好氧运行方式。同时监测了渗滤液中有机物浓度以压温度、pH值的变化。改变模拟垃圾柱的运行方式两个月以后。氨氯浓度由2000mg／L迅速下降至101．48mg／L，试验结果显示，准好氧运行方式可以解决生物反应器填埋场进入稳定阶段后存在的氨氮浓度高的问题，加速填埋场的稳定。

Experimental Study on Leachate from Anaerobic-quasi-aerobic Landfill

Through the indoor simulation experiments, when the anaerobic landfill pest, which is based on the leachate recirculation, reaches the stable state by and large, the quasi-aerobic operation way is adopted. Meanwhile the temperature, pH and the concentration of organic substances in leachate are monitored. Tw~ months later, NH3-N concentration in leachate decreases to 101.48mg/ L from 2000mg/L. The results show that the quasi-aerobic operation way can reduce the concentration of organic substances, such as NH3-N, so it accelerates the stabilization of the landfill site.
