微藻废水处理的研究现状及展望

Research status and prospect of microalgae wastewater treatment

微藻水处理技术作为一种废水处理方法,具有可再生、经济、环境友好的特点,已成为废水生物处理的必要手段。微藻可以利用废水中的污染物质提供自身生长的需要,对不同来源的废水进行生物净化,具有很大的潜力。本研究概述微藻在处理废水技术方面的应用,包括处理废水中的碳、氮、磷以及重金属(铜、锌、铬、镉、镍等)等多方面的应用,也概括各类微藻处理不同废水的条件和效率。青藏高原具有独特的气候条件,使高原微藻具有独特的环境适应性,此研究希望可以为高原微藻处理废水提供可行性参考。

As a wastewater treatment method,microalgae water treatment technology has the characteristics of being renewable,economical and environmentally friendly,and has become a necessary means of wastewater biological treatment.Microalgae can use the pollutants in wastewater to provide their own growth needs,and have great potential for biological purification of wastewater from different sources.This study summarized the application of microalgae in wastewater treatment technology,including the application of carbon,nitrogen,phosphorus and heavy metals(copper,zinc,chromium,cadmium,nickel,etc.)in wastewater treatment,and also summarized various types of microalgae treatment,as well as conditions and efficiencies of different wastewaters.The Qinghai-Tibet Plateau has unique climatic conditions,which make the plateau microalgae have unique environmental adaptability.This study hopes to provide a feasible reference for the treatment of wastewater by the plateau microalgae.
