Abstract:
In the global effort to reduce CO2 emissions, the concurrent enhancement of pollutant degradation and reductions in fossil fuel consumption are pivotal aspects of microalgae-mediated wastewater treatment. Clarifying the degradation mechanisms of bacteria and microalgae during pollutant treatment, as well as regulatory biolipid production, could enhance process sustainability. The synergistic and inhibitory relationships between microalgae and bacteria are introduced in this paper. The different stimulators that can regulate microalgal biolipid accumulation are also reviewed. Wastewater treatment technologies that utilize microalgae and bacteria in laboratories and open ponds are described to outline their application in treating heavy metal-containing wastewater, animal husbandry wastewater, pharmaceutical wastewater, and textile dye wastewater. Finally, the major requirements to scale up the cascade utilization of biomass and energy recovery are summarized to improve the development of biological wastewater treatment.
摘要:
在全球减少二氧化碳排放的努力中,污染物降解的同时增强和化石燃料消耗的减少是微藻介导的废水处理的关键方面。明确了污染物处理过程中细菌和微藻的降解机理,以及监管生物脂质生产,可以提高过程的可持续性。本文介绍了微藻与细菌之间的协同和抑制关系。还综述了可以调节微藻生物脂质积累的不同刺激剂。描述了在实验室和开放池塘中利用微藻和细菌的废水处理技术,以概述其在处理含重金属废水中的应用。畜牧业废水,制药废水,和纺织染料废水。最后,总结了扩大生物质梯级利用和能源回收的主要要求,以促进废水生物处理的发展。
