摘要
微藻可以高效利用废水中的部分小分子有机质、氮和磷等污染物合成生物质,并达到处理废水的目的。近年来,利用微藻进行农业废水、工业废水、城市废水和含农药以及抗生素等有害废水的处理等有了一些新的尝试。本文中,笔者重点分析了微藻处理废水中藻种选育、藻菌共培养、藻菌絮体、工艺集成和反应器设计以及可持续综合开发等关键技术问题。其中,藻菌共培养可以发挥微藻和菌的各自优势,提高废水处理效率。藻菌絮体技术还具有便于采收的特点,具备进一步研究的潜力。针对不同废水的处理需求,笔者提出合理构建绿色可持续发展路线,推动微藻处理废水的更广泛应用。
Microalgae can efficiently utilize some organic matter with small molecular weight,nitrogen and phosphate,and convert them into biomass.At the same time,wastewater treatment is achieved.In recent years,some studies were performed to treat the agriculture wastewater,industrial wastewater,municipal wastewater and toxic wastewater containing pesticides and antibiotics.We analyze the critical technological problems including selection of microalgae species,co-culture of microalgae and bacteria,microalgal bacterial flocs,process integration and photobioreactor design.Co-culture of microalgae and bacteria can present the individual advantages and improve the treatment efficiency.Microalgae bacterial flocs has additional characteristic and the potential for further development.It is necessary to establish green route for the sustainable development of microalgae wastewater treatment.It is the most important to improve the wastewater treatment efficiency and promote the wider utilization in the future.
