膜组件选取的指标体系与中试框架——以欧洲超滤应用为例

Index System for the Selection of Membrane Modules and Pilot Framework:Take European Ultrafiltration Application as an Example

基于超滤膜技术经济指标,构建旨在进行膜组件选取的指标体系与中试框架,为用户在信息不对称情况下选择膜组件提供了参考。其中,膜组件选取指标体系分为四级,第一级指标包括经济性、安全与环保、质量保障三方面内容,由多项二、三级指标量化支撑,技术指标处于体系的第四级,可作为区分产品性能的具体指标参数。依据欧洲市场调查数据,对膜组件选取指标体系中涉及固定投资与运行费用的指标点进行了重点分析,明确中试需要注意的关键对比参数。在此基础上,总结提出超滤膜水处理中试对比试验的基本原则与试验构架,进而以膜组件性能对比试验为例,对指标体系进行了应用性总结。

Based on the technical and economic indicators of ultrafiltration membrane,the index system and pilot test framework for membrane module selection were constructed,which provided a reference for users to select membrane components under asymmetric information. Among them,the selection index system of membrane module is divided into four levels: the first level includes economy,safety and environmental protection,and quality assurance. It is supported by a number of secondary and tertiary indicators. The technical indicators are in the fourth level of the system,which can be used as specific index parameters to distinguish product performance. Based on the survey data from European market,this paper focuses on the analysis of the index points related to fixed investment and operation cost in the selection index system of membrane module,and clarifies the key comparative parameters that should be paid attention to in the pilot test. On this basis,we propose the basic principles and experimental framework of the pilot scale test of ultrafiltration membrane water treatment. We then take the performance comparison test of membrane module as an example to summarize the application of the index system.
