AI Technical Summary
Existing technologies cannot realistically simulate the biodegradation process of nitrosamines in groundwater environments, especially under conditions of low nutrition, low flow rate, weak disturbance, and synergistic effects of natural microorganisms. Furthermore, it is difficult to dynamically and continuously monitor nitrosamines and their degradation products, leading to deviations between experimental results and actual environmental conditions.
Using a microcosmic reaction system, actual groundwater samples and soil matrix were used to set up aerobic and anaerobic conditions. Combined with high and low pollution water and soil, nutrients were added, and dynamic continuous monitoring of nitrosamines and degradation products was carried out. The microbial community was analyzed by 16S rDNA and the decay half-life was calculated.
This study achieved a realistic simulation of the biodegradation behavior of nitrosamines, improved the reliability and repeatability of experimental results, revealed the degradation kinetics and microbial action mechanism, and provided technical support for groundwater pollution remediation.
