摘要
高难废水指的是工矿企业生产产生的一种具有高盐、成分复杂、色度高、难生化降解及毒性大的难处理废水,对水体污染严重,处理成本极高。综述了国内外高难废水处理技术现状及存在问题,重点介绍了臭氧催化氧化技术、四相催化氧化技术、湿式氧化处理技术及水力空化协同臭氧氧化水处理技术的原理、特点及应用领域等。
High-difficult waste water refers to a kind of refractory wastewater with high salt,complex composition,high chroma,difficult biochemical degradation and high toxicity,which is produced by industrial and mining enterprises.It has serious pollution to water bodies and high treatment cost.This paper reviews the current status and existing problems of high-durable wastewater treatment technology at home and abroad,and focuses on the principles,characteristics and application fields of ozone catalytic oxidation technology,four-phase catalytic oxidation technology,wet oxidation treatment technology and hydrodynamic cavitation combined with ozone oxidation water treatment technology.
