| 摘 要： | 在用实验室矿化垃圾填充的准好氧生物反应床上,对渗滤液进行了1次过流处理.结果表明,当每立方米矿化垃圾的水力负荷为40 L/d、有机负荷(以化学需氧量计)为480 r/d、氨氮负荷约为12 r,/d时,渗滤液中化学需氧量的去除率为92%以上,处理前后渗滤液中有机物由26种减少到10种,对氨氮和总氮的去除率分别为98%和96%以上.随着氨氮负荷的增大,当进水TN为523～2 611 mg/L时,去除率保持在75%～96%之间.因此,准好氧矿化垃圾床同时实现了对渗滤液中有机污染物和氮污染物的处理,能承受较大氮负荷的冲击. |

| Abstract: | A semi-aerobic bioreactor, filled in with aged refuse in a laboratory, was used to treat leachate by once injection. As a result, in the case of a hydraulic load of 40 L/d, a COD (chemical oxygen demand) organic load of 480 g/d and an ammonia nitrogen (NH_3-N) load of about 12 g/d per cubic meter aged refuse, the COD removal efficiency was over 92%, and the organic pollutants were reduced from 26 kinds to 10 kinds after treatment. At the same time, the removal efficiencies of the ammonia nitrogen and the total nitrogen (TN) were 98% and 96%, respectively. With the ammonia load increasing, when the influent concentration of TN in the leachate was 523 to 2 611 mg/L, the removal efficiency was kept between 75% and 96%. Therefore, the bioreactor can simultaneously realize efficient removal of organic and nitrogen pollutants in the leachate, and tolerate a large nitrogen load. |
