太阳光对湖泊中有机污染物降解的研究进展

论述了太阳光对湖泊水体中有机污染物降解作用的研究,就其降解机理、动力学特征、作用对象及降解产物等作了逐一介绍.阐明了太阳光对生物降解湖泊水体中有机污染物具有协同作用,也概述了光降解作用受pH、溶解性有机物(DOM)、水深与水体运动、地理、水文、水质与气候等因素的影响.并对实验室模拟条件下的降解与自然条件下的降解进行对比,提出今后该领域的发展前景与研究方向.

Advances in the research on the solar radiation photodegradation of organic pollutants in lakes

This paper reviews the advances in the research on the solar radiation photodegradation of organic pollutants in lakes, the mechanism and kinetics of photodegradation, targets of photodegradation and their products are introduced one by one. Solar radiation has cooperation with biodegradation of the organic pollutants in the lake water. Some influencing factors on photodegradation such as pH, dissolved organic matter, depth and motion of water, geography, water quality and weather are also introduced. In the end, the authors compare the degradation effect in the laboratory with that of under the natural condition and prospect direction of this field.
