摘要
构建曝气式矿化垃圾反应器,研究其对高水力负荷垃圾渗滤液的处理效果。结果表明,在水力负荷为70 L/(m^3垃圾·d),曝气量为0.744 m^3/(m^3垃圾·d)的条件下,进水渗滤液中COD_(Cr)、氨氮、总磷、总氮质量浓度分别为4 776~5 305,1 659~2 200,15~22,2 115~2 578 mg/L时,COD_(Cr)、氨氮、总磷的平均去除率分别为75.2%,96.0%,89.0%。总氮去除率呈下降趋势,从56.6%降至16.1%,平均去除率为25.8%。
The aerated aged refuse reactor is constructed for the study of its control effect on landfill leachate with high hydraulic loading. Results show that,at a hydraulic load of 70 L/（ m^3 rufuse·d） and aeration rate of 0. 744 L/（ m^3 refuse·d）,the average removal efficiency of CODCr,ammonia nitrogen and total phosphorus can reach 75. 2%,96. 0% and 89. 0% respectively when the leachate influent CODCr,ammonia nitrogen,total phosphorus,total nitrogen concentrations is 4 776 - 5 305,1 659 - 2 200,15 - 22 and 2 115 - 2 578 mg/L,but the removal of total nitrogen is decreased from 56. 6% to 16. 1% and the average removal rate is 25. 8%.
