摘要
本文旨在评价污水处理厂新兴污染物排放对水体生态环境的影响.首先介绍了新兴污染物的特点和分类,并列举了常见的新兴污染物及其来源.接着分析了新兴污染物对水体生态环境的影响机制,包括生物毒性和生态效应以及累积特性和传播途径,并针对新兴污染物的监测与评估方法进行了探讨,涵盖了污水处理厂出水监测技术和环境样品分析方法.最后,提出了新兴污染物的水体生态风险评估方法,包括风险评估模型和指标体系,并展望了未来研究方向.
Abstract
This study aims to evaluate the impact of emerging pollutant emissions from wastewater treatment plants on aquatic ecosystem.Firstly,the characteristics and classification of emerging pollutants are introduced,along with examples of common emerging pollutants and their sources.The mechanisms of emerging pollutants'effects on aquatic ecosystem,including their ecotoxicity,ecological impacts,accumulation characteristics,and transmission pathways,are analyzed.Methods for monitoring and assessing emerging pollutants are discussed,covering wastewater treatment plant effluent monitoring techniques and environmental sample analysis methods.Furthermore,a framework for assessing the ecological risk of emerging pollutants in aquatic systems is proposed,including risk assessment models and indicator systems,along with future research directions.
