摘　　要：污水处理厂(sewage treatment plant,STP)是化学品分配转移的重要中转站,STP暴露预测是化学品环境暴露评估的重要手段。目前国际上主要使用STP模型预测化学品在STP中的归趋和暴露。该文概述了经典STP暴露预测模型及其建模方法,包括STP模型中使用的基本工艺,以及一些关键工艺参数,如污泥停留时间、水力停留时间、污泥负荷等对化学品归趋的影响。重点讨论了化学品在STP中的挥发、气提、吸附和降解4个主要过程的归趋机理及预测模型。对建立符合中国特点的STP模型提出了建议。Sewage treatment plant （STP） is an important transit point for the distribution and transfer of chemicals. STP for chemicals exposure prediction is the main part in environmental exposure assessment field. Currently the international mainly use the STP model to predict the fate and exposure of chemicals. First the international classical models and modeling methods for STP exposure prediction were reviewed, including the basic processes and some key process parameters such as the sludge retention time, hydraulic retention time, sludge load, etc. which impact the fate of chemicals, were described. Meanwhile, the mechanisms of four major fate （volatilize, gas stripping, adsorption, degradation） and prediction model were also detail discussed. Finally, the development of STP model according with Chinese characteristics was proposed.
