摘要

[Objective]The study aimed at treating wastewater treatment plant (WWTP) effluent by using bio-film reactor with filamentous bamboo as bio-carrier. [Method]With the aid of a continuous flow reactor,a bio-film reactor using filamentous bamboo as bio-carrier was used to treat WWTP effluent with low C/N ratio,and the removal effects of COD_(Cr) ,TN (total nitrogen) ,and NO_3~(-)-N in the wastewater were analyzed. [Result] The average removal rates of COD_(Cr) ,TN,and NO_3~(-)-N reached 47. 7%,23. 6% and 34. 5% when the C/N ratio of influent was around 2. In addition,a stable bio-film was formed very well in the secondary effluent with low C/N ratio and hardly degradable organic pollutants. The pollutants could be removed effectively because of the excellent surface characteristics and compositions of filamentous bamboo. [Conclusion]The research provides a new method to treat WWTP effluent with low C/N ratio.
