藻菌共生系统在废水处理中的研究进展

The research progress of the algae-bacteria symbiotic system in wastewater treatment

介绍了藻菌共生系统废水处理技术的主要类型,总结了影响藻菌共生系统运行稳定性和营养物质处理效果的主要因素,从氧气补充作用和资源回收潜力探讨了藻菌共生系统的应用潜力。分析认为:藻菌共生技术具有处理效率高、运行能耗低、剩余污泥量少和资源化潜力高等优势,但控制条件严格,对温度、光照等环境因素要求较高;为了更好地实现该技术的产业化,未来还需要进一步优化光生物反应器设计、藻类光能利用、工艺参数控制和微藻生物质的综合利用。

The main types of wastewater treatment technologies with the algae-bacteria symbiotic system were introduced.The main factors affecting the stability of the alga-bacteria symbiotic system and the treatment effect of nutrient were summarized.The application potential of this system was discussed from the oxygen supplementation and resource recovery potential.The results show that the algae-bacteria symbiotic technology has the advantages of high treatment efficiency,low energy consumption,low excess sludge production and high resource potential,but it requires strict control conditions and environmental factors such as temperature and light.In order to realize the industrialization of this technology,it is necessary to further optimize the design of photo-bioreactors,the light energy utilization of algae,the control of process parameters and the comprehensive utilization of microalgae biomass.
