Abstract:

Membraneas a modern effective chemical separation technologyhas been applied in a number of industries for 20 years. Researchers are recently studying a new way of substance characterization by membrane gradient separation. Membrane gradient separation achievements abroad are used in separation of ultra colloidquantitative analysis of readily biodegradable substancesdetermination of the relationship between chemical oxygen demand and size distribution of pollutantsand biodegradable ability evaluation. In Chinaexploratory work presently focuses on molecular weight distribution of source waterpollutants characterization of landfill leachate and water quality analysis of coagulation effluent.

摘要:

膜作为一种新兴高效的化工分离技术20年来已经应用于很多行业,近年来膜梯度分离用于水质表征的方法受到国内外关注。本文综述了国内外膜梯度分离技术用于水质分析的研究进展膜梯度分离在国外已经应用在超胶体的定性、易降解组分的定量、化学耗氧量与粒径分布关系的分析以及可生化性评价等方面;国内目前在水源水分子量分布、垃圾渗滤液污染物特性表征和絮凝处理后水质分析方面有研究。
