2种深度氧化技术在工业废水处理中的应用实例比较

Engineering examples and comparison of two deep oxidation technologies in industrial wastewater treatment

简要介绍了臭氧氧化、曝气生物滤池(BAF)、Fenton氧化工艺的常见型式,并从处理规模、进出水水质、设计参数、主要构筑物及设备、经济指标、三废情况等方面介绍了臭氧氧化+BAF和Fenton氧化+沉淀过滤这2种深度氧化处理技术在部分工业废水处理工程中的应用。总结了2种深度处理技术的技术特点和适用范围,为废水深度处理技术的选择提供参考,并发现了在考虑废气处理、污泥处置及废水回用的情况下,臭氧氧化+BAF技术更具优势。

This paper briefly introduced the common types of ozone oxidation,BAF and Fenton oxidation processes.The applications of the combined process of ozone oxidation and BAF and the combined process of Fenton oxidation and precipitation filtration in some industrial wastewater treatment projects were explained in-depth,from aspects of project scale,water quality,design parameters,main structures,equipment,economic indicators,and pollutants.We also summarized the technical characteristics and scope of the application,which provides a reference when selecting different advanced wastewater treatment technology.Considering the treatment of waste gas,sludge and wastewater reuse,the combined process of ozone oxidation and BAF technology has more advantages.
