Abstract
The problem of environmental pollution is becoming increasingly serious, and the traditional treatment methods have limitations in the face of complex pollutants, so the microbial technology has attracted wide attention due to its efficient, economic and environmentally friendly characteristics. The purpose of this study is to explore the application potential and mechanism of environmental engineering microorganisms in pollution control, and to systematically analyze the degradation efficiency of specific functional microbial communities on organic pollutants, heavy me tals and composite pollution by combining laboratory simulation and field tests. In this study, typical pollutants were selected as target ob jects, molecular biology techniques were used to identify key microbial populations, and the mechanism of action was revealed by the me tabolic pathway analysis. The results showed that the optimized microbial community showed significant degradation capacity under multiple contamination conditions, with some strains acting together to improve the pollutant removal efficiency by more than 30%.
