摘要
污水处理厂化学品环境归趋模型是化学品末端管控的重要工具.当前针对污水处理厂中化学品迁移、转化和分布预测的模型开发及应用逐渐增加,但相关模型种类较多、适用性各具特点,尚缺乏污水处理厂化学品环境归趋模型的综合比较和应用清单报道.本文汇总了目前已用于污水处理厂内化学品环境归趋模拟的模型与化学品适用清单,根据模型建模机理,将其分为三类:基于逸度原理(STP)、基于质量浓度(SimpleTreat、WW-TREAT、WATER9、TOXCHEM和WEST等)以及基于活度原理(Activity SimpleTreat)的污水处理厂化学品环境归趋模型.本文系统性介绍了相关模型的基本结构、原理和不同场景下化学品归趋研究的应用情况,概述其在表达形式、输入参数、输出结果以及适用案例等方面的局限性和优点,结合数百个模拟/监测数据集进一步验证各类模型的准确性,并探讨其不确定性重要来源.文章为目前污水处理厂化学品环境归趋模拟研究提供了更清晰的现状分析,为新污染物末端治理工具的选择提供了参考依据,并总结了该领域的发展趋势和前景.
Abstract
The environmental fate model for chemical in sewage treatment plant is an important tool for end-of-pipe control of chemicals.Recently,there has been a gradual increase in the development and application of models designed to predict chemical migration,transformation and distribution in sewage treatment plants.However,given the variety of available models,each with its unique suitability and characteristics,a comprehensive review on their comparisons and applications is needed.This article provides an overview of the various models currently in use for simulating the environmental fate of chemicals in sewage treatment plants and the chemicals they are applied to.These models are categorized into three groups based on their internal mechanisms:fugacity-based models(STP),mass concentration-based models(SimpleTreat,WW-TREAT,WATER9,TOXCHEM and WEST),and activity-based models(Activity SimpleTreat).Each model is systematically explored in terms of its basic constructions,mechanisms,and applications on chemical fate simulation in different scenarios.Additionally,the article outlines the limitations and strengths of each model,considering factors such as expression forms,input parameters,output results and applicable cases.To further validate these models,the article compares extensive modeling data with monitoring data,identifying key sources of uncertainty in the process.This comprehensive analysis provides a clearer picture of the current state of simulation research on the environmental fate of chemicals in sewage treatment plants.The article aims to guide the selection of tools for end-of-pipe control of new pollutants and summarizes the development trends and prospects in this field.
