基于微生物共代谢的工业废水混合处理研究现状与展望

随着工业的发展，工业废水产量与日俱增，废水中持久性强、毒性强的难降解有机物严重影响废水的处理效率。基于微生物共代谢理论，易降解有机质能显著提高微生物对难降解有机物的处理效率。然而，目前污、废水处理过程中易降解有机质主要来源于人工添加商业碳源，提高了运行成本，且产生大量碳排放。将部分富含易降解有机物的废水作为易降解有机质与难降解有机废水混合处理，能提高难降解有机物的处理效率，实现废水资源化。阐述工业废水的特征与危害，论述微生物共代谢机制的研究现状，重点综述基于微生物共代谢的食品工业废水、纺织废水、造纸废水、部分制药废水、生活污水及工业园区内部废水混合处理研究与应用案例，提出废水混合处理应用的前景与挑战，对其未来发展进行展望，以期为废水混合处理技术的应用提供指导，为建设绿色低碳工业园区、实现废水绿色低碳处理提供参考。

Literature review of industrial wastewater mixed treatment based on microbial co-metabolism

With the development of industry, the industrial wastewater output has been increased over time. However, the refractory and toxic organic compounds in industrial wastewater restrict the treatment efficiency significantly. Based on the co-metabolism theory of microorganisms, the addition of readily biodegradable organic substrates has been successfully employed to improve the removal efficiency of refractory organic compounds. However, the readily biodegradable organic substrates used in practical wastewater treatment process mainly come from the artificial addition of commercial carbon sources, which would increase the operating cost and emit a large amount of carbon. Mixing some wastewater rich in readily biodegradable organic substrates with refractory organic wastewater may be a good strategy, which can not only improve the refractory organic treatment efficiency, but also realize the wastewater recycling. This paper reviews the characteristics and hazards of industrial wastewater, research statues of co-metabolism mechanisms, and focuses on the research and application cases of mixed treatment of wastewater, including food wastewater, textile wastewater, paper making wastewater, some pharmaceutical wastewater, domestic sewage and wastewater in the industrial park. Meanwhile, this paper proposes the prospects and challenges of wastewater mixed treatment, as well as its future development. The aim of this paper is to provide guidance for the wastewater mixed treatment technology application, green and low-carbon industrial park construction, in order to achieve green and low-carbon wastewater treatment.
