反渗透浓水中难降解有机物的去除技术研究进展

摘要

有机污染物是阻碍反渗透RO浓水达标排放或资源化利用的关键因素之一。对RO浓水难降解有机物的去除方法进行概括总结，阐述了生物法、铁炭微电解法和高级氧化法的研究现状，尤其对高级氧化法的研究进展和存在问题进行了详细的分析。在此基础上，提出高级氧化－活性炭吸附、高级氧化－生物等联合技术是今后研究的主要方向。%Organic pollutants are one of the key factors which obstruct RO concentrate to achieve discharge standard or resource utilization. In the paper,the methods for removing non-degradable organic substances in RO concentrate are concluded and summarized. The present research status of biological method ,Fe/C micro-electrolysis method , and advanced oxidation processes(AOPs) are expounded in detail,and the research progress and existing problems are analyzed especially in detail. Based on these ,it is proposed that the united technologies of advanced oxidation-activated carbon adsorption,advanced oxidation-biology,etc. are the main research directions in the future.
