摘要:
Artificial wetlands (AWs) planted with Acorus Calamus L. and coupled with weak electric field (WEF) were constructed to investigate the effects of flow direction, hydraulic retention time (HRT), and WEF intensities on the removal of uranium and manganese from leachate of uranium tailings impoundment (LUTI), the distribution characteristics of the uranium and manganese in the AWs, and the growth and physiological responses of the plants in them. The results showed that the optimized removal rates of uranium and manganese from LUTI were observed ...
