摘　　要：通过构建准好氧矿化垃圾床反应器,探究了生物炭的投加量对准好氧矿化垃圾床渗滤液中的COD_(Cr)、UV_(254)、NH_(4)^(+)-N和TN去除及N_(2)O排放的影响。结果表明:生物炭可以有效提高COD_(Cr)、UV_(254)、NH_(4)^(+)-N和TN的去除率,同时减少N_(2)O的排放,随着生物炭投加量的增加减排量增大,最大减排达到了34.08%。In this study,we conducted a semi-aerobic aged refuse bioreactor and studied the effect of biochar dosage on the removal performance of COD_(Cr),UV_(254),NH_(4)^(+)-N,and TN in the leachate and N_(2)O emissions.The results show that the biochar can enhance the removal rates of COD_(Cr),UV_(254),NH_(4)^(+)-N and TN and reduce N_(2)O emissions,and with the increase of biochar dosage,the emission reduction increases,the maximum reduction is 34.08%.
