【摘要】：由于水体中新兴污染物不断增多,如何运用新型处理技术来弥补传统污水处理方法的缺陷已成为当前的研究热点。光催化耦合微生物同步降解污染物(ICPB)在保留生物法处理废水优点的同时,耦合了光催化高效、迅速的特性,可实现对多种污染物质的有效降解,节约了能源和成本,成为水体污染物有效去除的一个重要研究方向。ICPB体系主要由多孔载体、光催化材料及生物膜构成;其主要的工作原理是通过光激发载体上的光催化材料,将水体中难生物降解的污染物转化为可生物降解的物质,同时在载体内部微生物的代谢作用下,将这些污染物的中间降解产物继续矿化。本文根据光催化耦合微生物同步降解污染物体系中的关键构成,归纳总结了载体种类、光催化材料和负载生物的研究进展,探讨了该方法在去除水体污染物中的实际应用,并展望了其将来发展的方向和趋势。
[Abstract]:Due to the increasing number of new pollutants in water, how to use new treatment technology to remedy the defects of traditional wastewater treatment methods has become a hot research topic. The simultaneous degradation of (ICPB) by photocatalytic coupling microorganisms not only preserves the advantages of biological treatment of wastewater, but also coupled the characteristics of high efficiency and rapidity of photocatalysis, which can realize the effective degradation of various pollutants and save energy and cost. ICPB system is mainly composed of porous carrier, photocatalytic material and biofilm. Its main working principle is to convert the difficult biodegradable pollutants in water into biodegradable substances through photocatalytic materials on the photoexcitation carrier, and at the same time, under the action of microorganism metabolism inside the carrier, The intermediate degradation products of these pollutants are further mineralized. Based on the key components of photocatalytic coupling microorganism system for simultaneous degradation of pollutants, this paper summarizes the research progress of carrier, photocatalytic materials and supported organisms, and discusses the practical application of this method in the removal of pollutants in water. The direction and trend of its future development are also prospected.
