应用微藻及人工藻菌处理沼液沼气的研究进展

Advances and Prospects of Applying Microalgal and Artificial Algalfungal Symbiotic System in Disposing Biogas and Biogas Slurry

厌氧发酵生产沼气是处理农业固体废弃物利用的理想途径。但现有沼气生产工艺产气品位低下,CO_2含量过高,同时沼液污染严重,使得大量农业固废难以通过厌氧发酵达到有效的资源化利用。微藻与人工藻菌共生体是实现固废厌氧发酵中沼液资源化利用,解决沼气品位低下等问题的一种新途径,已引起有关研究者高度重视。该文论述了微藻与人工藻菌共生体在沼液污染物去除、沼气能源品位提升等方面的研究现状,并指出了微藻与人工藻菌共生体在生物处理沼液沼气的应用前景和发展趋势,以期引起同行的重视并推动该领域的进一步发展。

Developing strategies for producing biogas by anaerobic fermentation is an ideal utilization way to process agri-cultural solid wastes. However, there still exist many problems, such as low biogas, high CO2 content, and biogas slurry pollution. An microalgal and artificial algal-fungal symbiotic system is a new approach to realize utilization as resources for bio-gas slurry and to upgrade biogas, which has received considerable attention in recent years. Herein, we discussed the applica-tion of microalgal and artificial algal-fungal symbiotic system in realizing the utilization of resource recycling for biogas slur-ry and upgrading biogas, which was expected to appeal the attention of peers and promote the further development in this field.
