人工湿地中,植物除本身可以直接吸收含氮、磷化合物外,其根系分泌物可促进某些嗜磷、氮细菌的生长,促进氮、磷释放、转化,从而间接提高净化率。有植物的湿地系统,以上细菌数量显著高于无植物系统,且植物根部的细菌数比介质中高1-2个数量级。在除氮机制中,植物起主导作用,而在磷的净化过程中;细菌是一个限制性因子。

The relationship between the removing rates of TP,NH 3 N and the distribution of bacteria in artificial wetlands was studied.The results showed that plants play the major role in the mechanism of removing N,and in the process of removing P,bacterias transformation rate of compounds with P is a restricted factor.Plants existing is b...
