Removal of ammonia nitrogen from a synthetic landfill leachate by immobilized microorganism system
固定化微生物法去除模拟渗滤液中氨氮的研究

A biological treatment with immobilized microorganism was successfully developed in a biological aerated filter(I-BAF) to treat synthetic landfill leachate.The regulatory effects of pH and dissolved oxygen(DO) on nitrogen removal were investigated.It was demonstrated that the I-BAF system started up quickly and it was very efficient for COD and nitrogen removal from synthetic landfill leachate with efficiencies of 97.1% and 99.9%.When pH and DO were controlled at 7.5~8.5 and 4.0 mg/L,respectively,maximum of...
