Abstract: The goal of this experiment is to improve the performance of constructed wetland for the malodorous black river. The average removal rates of the new bio-packing tank on system CODCr ，NH3-N and TP were 36.63%, 29.41% and 29.22%, respectively, and all being higher than that of the filling purification tank. A Scanning Electron Microscope (SEM) analysis showed that the new flexible medium was characterized by fibrous, large surface area and easy to membrane-hanging. This new tank can be used for recovering the ecosystem of water body, and as a good supplement to constructed wetland.

Key words: flexible medium, pre-treatment, biofilm, malodorous river water, flexible medium, pre-treatment, biofilm
