摘要
城市固废焚烧(MSWI)是实现废弃物管理和能源回收的关键技术之一,该过程不可避免地产生持久性有机污染物二英(DXN)。该污染物产生机理至今模糊不清且难以直接检测。为洞悉DXN生成、分解、再生成、吸附和排放的全生命周期机理,本文提出了基于耦合数值仿真和模糊森林回归的DXN全生命周期模型构建方法。首先,采用FLIC、Aspen Plus和Aspen Adsorption开发DXN全生命周期数值仿真模型。随后,进行双正交实验设计与实施以获得多工况下虚拟机理数据。最后,利用T-S模糊森林回归算法(TSFFR)建立DXN全生命周期模型。结果表明,该模型能够获取MSWI过程DXN全生命周期不同位置的浓度,为后续实现污染减排与优化控制提供了有效支撑。
Municipal solid waste incineration(MSWI)is a critical technology for waste management and energy recovery.The process inevitably generates trace amounts of persistent organic pollutant dioxins(DXN).The generation mechanism of this pollutant is still unclear and difficult to directly detect.To gain a comprehensive insight into the full lifecycle mechanism of DXN generation,decomposition,re-generation,adsorption and emission,a full lifecycle prediction model for DXN based on multi-software coupled numerical simulation and fuzzy forest regression was proposed.Firstly,a DXN full lifecycle numerical simulation model was developed using FLIC,Aspen Plus and Aspen Adsorption;subsequently,the DXN simulation mechanism data under multiple working conditions were obtained based on the design and implementation of bi-orthogonal experiments;and finally,a DXN full lifecycle prediction model was established by using the T-S fuzzy forest regression(TSFFR)algorithm.The results showed that the model c ould obtain the DXN concentration of the full lifecycle,which provided an effective support for the realization of pollution reduction optimal control.
