复合垂直流构建湿地基质微生物类群及酶活性的空间分布

Space Distribution of Microorganisms and Substratum Enzymes in Integrated Vertical Constructed Wetland

对构建湿地基质微生物类群数目及酶活性的空间分布特点进行了研究 ,为进一步深入研究构建湿地净化污水的机制提供了可能。研究表明 :(1)不同月份构建湿地基质的微生物类群数目是不相同的。 (2 )基质不同层次之间其微生物类群数目不相同 ,上层数目较中下层多 ,最多几乎达三个数量级。(3)下行流池中的微生物类群数目较上行流池多。 (4)下行流池中的脲酶活性较上行流池高 ,且上层高于中下层。 (5 )

This paper studies the space distribution of microorganisms and substratum enzymens in integrater vertical constructed wetland(IVCW).The results show that 1) numbers of microorganism in wetlands constructed in different months vary;2) numbers of microorganism in different layers of substratum vary,with more in the upper than in the middle and lower parts;3) the number of microorganism in the downflow tank is much bigger than that in the upflow tanks;4)Substratum urine activities in the downflow tank are higher than those in the upflow tank;5)Substratum phosphates activities in the upflow tank are much higher than those in the downflow tanks.
