| 摘 要： | 研究了复合金属氧化物（LDO）用于处理垃圾渗滤液中氮的可行性,并与传统吸附剂粉末活性炭（PAC）进行了比较,考察了投加量、振荡速度、吸附时间、吸附温度、pH等因素对处理效果的影响。结果表明,当垃圾渗滤液中总氮浓度为561mg/L、LDO投加量为6g/L、振荡速度为170r/min、吸附时间为60min、温度为25℃、pH值为11时,LDO对总氮的吸附量最高,达到41mg/g。在相同条件下,LDO对总氮的吸附量是PAC的2.5—3.5倍。

| Abstract: | The feasibility of treatment nitrogen of landfill leachate by layer double oxides（LDO）was studied,and the traditional adsorbent powder activated carbon（PAC） was made a compare with LDO.The adsorption effects of LDO dosage,adsorption time,vibration rate,adsorption temperature,and pH value were investigated.The results indicated that the adsorption capacity of LDO reached to 41mg/g when the LDO dosage was 6g/L,shaking speed was 170r/min,the adsorption time was 60min,the premature was 25℃ and the pH value was 11.The adsorption capacity of LDO was 2.5 to 3.5 times comparing with PAC in same conditions. |
