摘要
焦化、印染、制革等工业中产生的废水呈现出有机污染物成分高、色度深、悬浮物含量占比大、可生物降解组分低等特点。常见的用混凝沉淀+生物降解技术处理上述工业废水,达不到相应的出水水质条件。本文综合阐述了臭氧-生物活性炭过滤的基本原理、特征及发展状况,并对该技术在深度处理过程中所面临的问题展开了探讨,最后进行了展望分析。希望臭氧-生物活性炭过滤能够得到进一步的优化和发展。
The wastewater from industries such as coking,printing and dyeing,and tanning has characteristics of high concentration of organic pollutants,high concentration of suspended solids,deep chroma,and low biodegradable components.While treating the wastewater by conventional coagulation sedimentation+biodegradation technology,corresponding effluent quality requirements cannot be met.This paper comprehensively discusses the principle,characteristics and development status of ozone-biological activated carbon filtration.And the problems existing in this technology are discussed.Finally,a prospect analysis is carried out.It is hoped that the ozone-biological activated carbon filtration can be further optimized and developed.
