摘要
以非稳定期垃圾填埋场的渗滤液为对象，研究了水解／好氧MBR组合工艺对COD和氮污染物的去除效果和规律。在HRT为1～4．7d、回流比为300％以及进水的COD为400～7600mg／L、氨氮为247．1～1643．8mg／L、TN为258．7～1743mg／L的条件下，对COD、氨氮和TN的去除率分别为80％～88％、〉99％和70％～82．2％，说明该组合工艺对渗滤液中的COD和氮污染物具有较好的去除效果。
The treatment of the instable landfill leachate by the hydrolysis/aerobic MBR process was investigated. When the HRT ranges from 1 to 4.7 d, the reflux ratio is 300% , and COD, ammonia nitrogen and total nitrogen in the influent range from 400 to 7 600 mg/L, from 247.1 to 1 643.8 mg/L and from 258.7 to 1 743 mg,/L respectively, the removal efficiencies of COD, ammonia nitrogen and total nitrogen are 80% to 88% , more than 99% and 70% to 82.2% respectively. These results show that the hydrolysis/aerobic MBR process is effective for reducing COD and nitrogen from the leachate.
