摘要
利用藻类净化污水是一项污水资源化生物技术。常规的藻类处理系统难以达到藻类高生物量生长及发挥净化潜力。近年来,国内外开展了大量的有关藻类培养和污水处理环境调控及其净化机理方面的研究,发展了几种新型的藻类处理系统,包括超浓度培养、固定化藻类、渗析培养、藻垫以及光生物反应器研制,以进一步提高净化效率,克服占地面积较大、停留时间较长、藻类收获难等缺陷。本文主要介绍了国内外有关藻类净化污水的研究现状及其发展趋势。
Utilising algae for sewage purification is a biotechnology of transforming sewage into re- sources.Normal algal treatment system is difficult to make algal grow up to maximum biomass and give full play to its purification potential.In recent years,many studies on pu- rification mechanism and environmental control of algal culture system were conducted.Sev- eral types of algal culture system have been developed,including hyperconeentrated algal culture,immobilized algal system,dialysis culture,algal mats and photobioreactor,for pur- pose of raising purification efficiency,decreasing area of land occupancy and making algal biomass easily harvested.This paper reviews the current status and progress of study on al- gae for sewage purification,and of which development tendency is also discussed.
