| 摘 要： | 针对中国目前城市普遍面临的污水处理厂升级改造问题,该文构建了一套基于数值模拟的城镇污水处理工艺筛选方法学。该方法学包含一个污水处理单元技术数据库、污水处理单元组合规则、污水处理工艺流程生成模型、具备不确定性分析功能的工艺处理效果模拟模型,并考虑了不同进水条件和出水标准要求的模拟情景设计。以30种单元技术为例,对该方法学予以初步应用。结果表明,该方法可识别出我国目前主要的水质达标约束为总磷(TP)指标,当出水条件要求严格时(TP<0.5m g/L),反渗透成为优势技术。

| Abstract: | An approach based on numerical modeling was designed to screen wastewater treatment processes to facilitate the upgrade in China's wastewater treatment plants. This methodology includes a database of the majority of treatment technologies, a series of treatment unit combination rules,a treatment efficiency simulation model with uncertainty analysis,and a scenario design method with different influent conditions and effluent requirements.Preliminary tests with 30 types of treatment technology show that the t... |
