城镇复合型污水处理厂水质监测与微生物分析
Water quality monitoring and microbiological analysis of urban complex sewage treatment plant
摘要
Abstract
Urban complex sewage treatment plants play a vital role in modern society.The bi-ochemical section is the core part of wastewater treatment and relies on a diverse microbial community to efficiently remove contaminants such as organics,nitrogen and phosphorus.Herein,the process water quality and microbial gene data of Urban complex sewage treat-ment plant L in the Yangtze River basin were systematically analyzed.The water quality at inlet and outlet the wastewater treatment plant,as well as the water quality at each stage of the treatment process,were continuously monitored,with particular focus on the biochemical section.By integrating operational and monitoring data,an assessment of the actual perform-ance of the sewage treatment plant was conducted to identify areas for improvement.The in-let water of industrial wastewater did not have an impact on the Urban complex sewage treatment plant L,the operation of each process section was basically stable,and the effluent water quality was basically up to standard.Furthermore,the metagenomic sequencing tech-nology is used to study the microbial community structure of activated sludge samples from the oxidation ditch of sewage treatment plant L.The results showed that there were microor-ganisms with different functions in the oxidation ditch.The diversity and relative abundance of microorganisms show differences between regions,and this difference reflects their ability to adapt to different environmental conditions.Through ecometabolomics analysis,the func-tional characteristics of microbial communities are explored.Different microbial species play their respective roles in key biochemical processes such as organic matter degradation,nitro-gen removal,and phosphorus removal.By analyzing the monitoring data and studying the genes of the microbial community,a comprehensive evaluation and diagnosis of the sewage treatment plant's operation can be achieved.关键词
