利用沼液养殖微藻研究进展

摘要

沼液具有量大、集中、价值密度低等特点,目前的土地消纳、达标处理等方式都难以达到经济可行的效果.利用沼液养殖微藻既能兼顾厌氧消化液的处理与资源化利用,也有利于降低微藻的养殖成本,是一条双赢途径.但是沼液既有利于微藻生长的因素,也有不利于微藻生长的因素.文章对沼液养殖微藻的有利因素、不利因素及其解决方法进行了系统总结与分析,并对发展前景进行了展望与建议.%Traditional liquid digestate processing technologies such as land application and standard treatment are lack of economic viability,because the digestate has the features of very large in volume,centralized distribution and low value density.Alternatively,microalgae cultivation using liquid digestate can be beneficial for both treatment and resources utilization of anaerobic digestate.It is also able to decrease microalgae cultivation cost.However,liquid digestate has both stimulative and harmful ingredients for microalgae growth.In this paper,both favourable and unfavourable factors of microalgae cultivation using digestate,and the corresponding solutions were summarized.The prospect and future development regarding microalgae cultivation were also reviewed in this paper.
