摘要
[目的]采用竹丝填料生物膜反应器,处理难降解且低C/N污水。[方法]利用连续流小试装置,以人工模拟污水为研究对象,采用以竹丝为生物载体的生物膜反应器处理难降解且低C/N污水,研究污水中CODCr、TN、NO3--N的去除效果。[结果]当进水C/N基本控制在2左右时,CODCr、TN和NO3--N的平均去除率分别为47.7%、23.6%和34.5%。竹丝填料能在低C/N且难降解污水中形成稳定的生物膜,其优良的表面特性和成分组成是其有效去除有机物和氮素污染物的主要成因。[结论]该研究为难降解且低C/N污水的处理提供了一种新方法。
[ 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 CODe,, TN （total nitrogen）, and NOs --N from the wastewater were analyzed. [ Result] The average removal rates of CODcr,TN,and NOs -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.
