摘要
为了研究不同基质人工湿地水质净化效果和胞外酶活性状态,选取煤渣、陶粒、碎石三种基质进行实验,结果表明:以氨氮、总磷和COD的去除率而言,基质为煤渣的人工湿地最高,其次是碎石,陶粒;对亚硝酸氮,以基质为陶粒的人工湿地去除率最高,达到80%以上;对总氮去除率三者没有显著性差异。蛋白酶、磷酸酶活性,在人工湿地中,以煤渣作为基质的活性最高,其次是陶粒和碎石,过氧化氢酶活性与其他三种正好相反。蛋白酶活性与亚硝酸氮的去除率呈负相关(P<0.05),与总磷去除率正相关(P<0.05),与总氮去除率相关性不明显;过氧化氢酶活性,与亚硝酸氮的去除率和COD的去除率正相关(P<0.05),与总磷去除率呈负相关(P<0.05);磷酸酶活性与总磷去除率和COD去除率正相关(P<0.05),与亚硝酸氮去除率相关性不明显。
In order to study the effects of wetland substrate on pollutant removal efficiencies and extracellular enzyme activity, chooses three kinds of substrate with its research. The results showed that: cinder substrate removal rate of ammonia nitrogen, total phosphorus and COD is best, followed by crushed stone and ceramic; ceramic substrate nitrite nitrogen removal rate can reach 80% or more; TN removal highest is gravel substrate, followed by ceramic and cinder, but there was no significant difference between the three. Protease, phosphatase activity, cinder substrate in the highest, followed by ceramic and gravel, catalase activity and the other three opposite. The activity of catalase was negatively correlated with the removal rate of nitrite nitrogen, the removal rate of total nitrogen and the removal rate of total nitrogen. The activity of catalase was correlated with the removal rate of nitrite nitrogen and the removal rate of COD,Which was negatively correlated with the removal rate of total phosphorus. The activity of phosphatase was related to the removal rate of total phosphorus and the removal rate of COD, but not to the removal rate of nitrite.
