基于竹丝填料的生物膜法处理难降解且低C/N污水的研究
Treatment of Hardly Degradable Wastewater with Low C/N Ratio Using Filamentous Bamboo as Bio-film Carrier
摘要
Abstract
[ Objective] The study aimed at treating hardly degradable wastewater with low C/N ratio using bio-film bioreactor with filamentous bamboo as bio-carrier. [ Method ] With the aid of a continuous flow reactor, the bio-film bioreactor with filamentous bamboo as bio-carrier was used for treatment of hardly degradable wastewater with low C/N ratio, and the removal effects of CODCr,TN (total nitrogen) ,and N03‐ -N from the wastewater were analyzed. [ Result] The average removal rates of C0DCr,TN,and NO3 ‐-N reached 47. 7% ,23. 6% and 34. 5% when the C/N ratio of influent was almost 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 hardly degradable wastewater with low C/N ratio.关键词
