摘要
针对单一填料类型人工湿地水质净化受限的问题,本研究构建了基于火山岩、煤灰渣和火山岩-煤灰渣组合填料的人工湿地,进行了单一填料和混合填料类型人工湿地的水质净化小试试验。研究结果表明,火山岩、煤灰渣和火山岩-煤灰渣混合湿地对NH _(4)^(+)-N和NO _(3)^(-)-N的平均去除率分别为80.86%,63.10%,83.87%和36.75%,23.79%,49.32%。火山岩和煤灰渣的协同作用强化了人工湿地的脱氮能力。
To address the problem of limited water purification in single filler type constructed wetlands,this study constructed wetlands based on volcanic rock,coal ash slag and volcanic rock-coal ash slag combination filler,and conducted a small trial test of water purification in single filler and mixed filler type constructed wetlands.The results showed that the average removal rates of NH _(4)^(+)-N and NO _(3)^(-)-N were 80.86%,63.10%,83.87%and 36.75%,23.79%and 49.32%for volcanic rock,coal ash slag and mixed volcanic rock-coal ash slag wetlands,respectively.The synergistic effect of volcanic rock and coal ash residue enhanced the nitrogen removal capacity of the constructed wetland.
