Abstract

Abstract

The purification abilities of ecofilter are affected by many factors. Different species of wetland plants may cause different purification abilities. For the improvement of applicability of ecofilter in Guizhou, we studied the purification abilities of main contaminants (COD, NH₃-N,TN and TP) in ecofilter with three wetland plants in Guizhou (Canna indica L.,Cyperus alternifolius,Acorus calamus L.). Through a comparison of the removal efficiencies of main contaminants we selected the optimal plants combination that could achieve the best purification ability of ecofilter in Guizhou. The result showed that: The ecofilter planted with Canna indica L. achieved the best purification abilities of COD, NH₃-N and TP, the removal efficiencies were up to 88% and 92% and 47%. The ecofilter planted with Canna indica L. and Cyperus alternifolius achieved the best purification ability of TN with the highest removal efficiency of 49%. The microbial community structures in different ecofilters were very similar. The main components were Proteobacteria, Chloroflexi and Acidobacteria. The biological diversity of nitrobacteria was low, mainly ammonia oxidizing bacteria. The biological diversity of denitrifying bacteria was high. The aerobiotic denitrifying bacteria was also detected.
