Abstract

With industrialization and population growth, water resources pollution has intensified, and traditional sewage treatment technology has been insufficient. Biofilm technology has become a research hotspot because of its high efficiency and energy saving. This paper discusses its latest development and application, including principle, classification, advantages such as efficient treatment, water quality adaptability, stable operation, easy maintenance and energy saving. This paper introduces new biofilm technologies such as MBR, IFAS systems and improved technologies, and discusses innovative applications of microbial fuel cells, technological optimization and immobilized enzyme technologies. Optimization strategies were proposed, including microbial community structure optimization, membrane component modification, operation parameter optimization, energy recovery and system self-purification capacity improvement. The feasibility of the new biofilm technology in improving the efficiency and effect of wastewater treatment was verified by case study. Finally, it summarizes the research results, emphasizes its important position and development potential in the field of future wastewater treatment, and looks forward to the future research direction, including technological innovation, application field expansion and interdisciplinary cooperation to support the efficient and clean use of water resources.
