| 摘 要： | 为研究建筑废物红砖和工业废物煤渣用作人工湿地脱氮基质的可行性，分别通过静态吸附实验和动态NH4+-N去除效果实验进行考察。结果表明，红砖和煤渣对NH4+-N最大静态吸附量分别为0.2533 mg/g和0.0533 mg/g，其吸附等温曲线均符合Freundlich型吸附方程，吸附常数分别为0.0419和0.0091；红砖煤渣组合对污水中NH4+-N平均动态脱除率达到41.18%，高于红砖的37.63%和煤渣的30.92%。

| Abstract: | In order to investigate the removal efficiency of NH4+-N on red brick and cinder as substrates of constructed wetland in both static and dynamic system. The results showed that the maximum adsorption capacity of NH4+-N on red brick and cinder in static adsorption system reached up to 0.2533 mg/g and 0.0533 mg/g, respectively. The isotherms of NH4+-N adsorption on both substrates accorded with the Freundlich equation, and their adsorption constants were 0.0419 and 0.0091, respectively. Moreover, the NH4+-N removal efficiency on combined substrates with red brick and cinder in dynamic system was up to 41.18%, higher than those on both single substrates(red brick 37.63% and cinder 30.92%, respectively). |
