Abstract
[Objective]The refractory organic pollutants in industrial wastewater pose a major challenge to environmental governance,which attributed by the compositional complexity and chemical stability of target contaminant.The traditional wastewater treatments,such as biotechnology,electrochemical method,flocculation,adsorption and precipitation etc.,are not sufficient for the complete removal of refractory organic pollutants in industrial wastewater.In this context,the modification and optimization of wastewater treatments is aiming at deep purification on refractory industrial wastewater,and further supporting the industrial sustainable development and environmental protection.[Methods]As the common treatment in wastewater treatment plants,traditional biological treatment has the advantage of low cost.Nevertheless,the refractory industrial wastewater with poor biodegradability and high biotoxicity significantly impede the microbial decomposition process,thus greatly limiting the application of traditional treatment in deep and efficient purification of industrial wastewater.Comparatively,advanced oxidation processes based on photocatalysis generate reactive oxygen species in photo-activation,which can efficiently decompose the refractory organic pollutants via chemical reactions(e.g.,reduction-oxidation reaction,etc.).It has been proven that photocatalysis is one of the most common and efficient treatments for the in-depth purification of refractory industrial wastewater.Recently,traditional biological treatment coupled with photocatalysis integrated process has been regarded as the hotspot of industrial wastewater treatments.In order to properly design the photoreactor with high catalytic performance and low cost,and further enhance the efficiency of composite biological-photocatalysis system,it's necessary to comprehensively optimize the photocatalytic technology and systematically select the best reaction conditions for the photocatalytic reaction system.[Results]coupling technology of photocatalysis and biological treatment has technical advantages of deep and efficient purification on refractory industrial wastewater,which attributing to the ability of photocatalysis treatment and further enhance the application potential by coupling the low-cost biological treatment.[Conclusion]The chemical-biological coupling process can effectively deal with the dilemma of refractory industrial wastewater treatment and is expected to be the critical strategy for deep purification on refractory industrial wastewater,which is of great significance for industrial sustainable development and environmental protection.关键词
