AI Technical Summary
Under low-temperature conditions, the metabolism of microorganisms in traditional biological treatment processes slows down, resulting in substandard treatment of domestic sewage, especially with high nitrogen and phosphorus content, which fails to meet discharge standards.
A low-temperature complex microbial community was prepared, including Flavobacterium, Aeromonas, Sphingosine monocytogenes, Pseudomonas, Trichomonas, Masséria, and Delftobacterium. The low-temperature complex microbial community obtained through enrichment culture was used to efficiently treat wastewater at low temperatures. The synergistic effect of these microbial species was utilized to improve the stability and degradation efficiency of the biofilm.
Under low-temperature conditions, the low-temperature composite microbial community can efficiently remove nitrogen and organic matter from domestic sewage, improve treatment efficiency, enhance biofilm stability, has a wide range of adaptability, good shock resistance, and short treatment time.
