Abstract
With the global shortage of water resources and water environment pollution, efficient and economic sewage treatment technology has become a research hotspot. In this study, biofilm method was the core to explore its application potential and optimization strategy in wastewater treatment. Through the construction of laboratory scale biofilm reactor, and combining with a variety of operating parameters (such as dissolved oxygen concentration, hydraulic residence time and packing characteristics), the removal effect of biofilm method on organic matter, nitrogen and phosphorus and other pollutants was systematically analyzed. The results show that the optimized biofilm system can significantly improve the removal efficiency of pollutants, in which the removal rate of chemical oxygen demand (COD) can reach more than 90%, and the removal rate of ammonia nitrogen is stable at about 85%. In addition, this study innovatively introduced new functionalized fillers, which effectively enhanced the attachment performance and microbial activity of biofilms, thus enhancing the impact load resistance of the system.
