利用废水培养微藻的研究进展

微藻被认为是一种有潜力的、可被开发为再生能源的重要生物材料。一些微藻种类具有较强的异养和混养能力,能直接利用有机物作为碳源。工农业生产和城市生活中所排放的废水中通常含有大量的有机碳、氮、磷等营养物质。利用废水培养微藻,一方面可以将废水中的碳、氮、磷等营养物质转化为具有更高价值的微藻生物质,另一方面又可实现废水的净化和营养物质的再利用。本综述了不同种类废水的特点,讨论了两类微藻培养模式的优劣,同时还探讨了微藻对营养元素的利用,并总结了微藻培养需突破的瓶颈。

Research Progress of Microalgae Cultivation Using Wastewaters

Microalgae are considered as an important biomaterial with potential for renewable energy.Some species of microalgae have strong heterotrophic and mixotrophic ability and can directly use organic matter as carbon source.Wastewater discharged from industrial and agricultural production and urban life usually contains a large amount of organic carbon,nitrogen,phosphorus and other nutrients.Using wastewater to cultivate microalgae,on the one hand,can transform the carbon,nitrogen,phosphorus and other nutrients in wastewater into microalgae biomass;on the other hand,can realize the decontamination of wastewater and the reuse of nutrients.This paper reviewed the characteristics of different types of wastewater,the advantages and disadvantages of two types of microalgae cultivation models,and the use of nutrients by microalgae.The bottleneck of microalgae cultivation was also summarized.
