| 摘 要： | 采用等温吸附、吸附动力学实验分别研究了泥灰页岩、黑色页岩、蜂窝煤渣和河砂等不同填料对城市生活污水中氨氮的吸附特征.结果表明:4种不同填料对氨氮的吸附量均随着氨氮起始浓度的增加而增大,且各填料对氨氮的最大吸附量大小次序依次为蜂窝煤渣(1.02 mg/g)泥灰页岩(0.86 mg/g)黑色页岩(0.77 mg/g)河砂(0.74 mg/g).当进水中氨氮浓度低于50 mg/L时,氨氮去除率随着进水氨氮浓度的增加而增大,当进水中氨氮浓度大于50 mg/L时,氨氮去除率随进水氨氮浓度的增加逐渐降低.4种填料对氨氮的吸附是快速吸附、缓慢平衡的过程.研究表明,蜂窝煤渣更适合作为人工湿地污水去除氨氮的填料. |

| Abstract: | The ammonia nitrogen adsorption characteristics of four different kinds of fillings included slimy shale,black shale,beehive cinder and river sand which were used in constructed wetland were studied by isothermal adsorption experiments and adsorption kinetics experiments.The results indicated that the ammonia nitrogen adsorption capacity of four fillings increased as the concentration of ammonia nitrogen solution increased and followed that beehive cinder(1.02 mg/g)>slimy shale(0.86 mg/g)>black shale(0.77 mg/g)>river sand(0.74 mg/g).If the NH4+-N density is increasing from 50 mg/L,the removal rate of NH4+-N would also rise but then gradually reduced.The results indicated that the ammonia nitrogen was adsorbed by four fillings is a fast adsorption but a slow equilibrium processed.The study indicated that the beehive cinder would be the best constructed wetland fillings in the four kinds of fillings. |
