摘要
印染废水对环境污染日益严重,且印染废水有机物含量高,具有色度大、水质变化大、成分复杂等特点。过硫酸盐高级氧化技术在工业水处理领域中已逐渐成为研究热点。综述了目前国内外过渡金属离子、热、紫外、碱活化、电活化、联合活化等过硫酸盐活化技术在印染废水中的研究进展,并简述了影响活化方式效率的重要因素。最后分析了过硫酸盐高级氧化技术在研究中的问题以及未来发展,为活化过硫酸盐工艺在废水处理领域进一步发展提供参考。
The pollution of printing and dyeing wastewater to the environment is increasingly serious,and the printing and dyeing wastewater has the characteristics of high organic content,large chroma,large changes in water quality,and complex components.Advanced persulfate oxidation technology has gradually become a research hotspot in the field of industrial water treatment.The research progress of transition metal ions,heat,ultraviolet,alkali activation,combined activation and other persulfate activation technologies in printing and dyeing wastewater treatment was reviewed.Finally,the problems and future development of persulfate advanced oxidation technology were analyzed,providing some reference for the further development of activated persulfate technology in wastewater treatment.
