Comparative analysis on application of biological filter for nitrogen removal in municipal wastewater treatment plant of Changjiang delta area
The paper introduces the characteristics of three kinds of biological filter for nitrogen removal in 4 municipal wastewater treatment plant in Changjiang delta area and makes the compre-hensive comparison on them from design parameters,upstream&-downstream process design and the practical operating conditions.The results shows that filter material is the core influencing fac-tors of filter form and operation cost and also determines upstream &-downstream process selection for biological filter for nitrogen removal.To ensure stable water quality,the rational distribution of nitrogen removal loading between biochemical treatment system and advanced treatment system should be considered overall based on the survey and analysis of current situation of plant condi-tions and treatment requirements with more and more strict national emission standard coming out.In the end,the problems and countermeasures of biological filter for nitrogen removal in actu-al engineering was summarized.
