摘要
焦化废水是一种典型高浓度、难降解有机工业废水。介绍了焦化废水来源与废水中存在的特征性有机污染物,强调水质分析是焦化废水处理工艺选择的前提。提出焦化废水污染控制应立足于"源头—末端处理"的全过程:源头控制和预处理对于降低生化系统负荷具有重要作用。重点比较了生物脱氮、生物流化床、固定化微生物和强化生物技术等生物处理技术的研究进展,指出深度处理工艺选择应考虑焦化废水出水水质特征和回用要求。
Coking wastewater is the typical industrial wastewater with high-concentration and refractory organic compounds. The sources of coking wastewater and the characteristics organic pollutants in it were introduced. It was emphasized that the analysis of water quality is the precondition of wastewater treatment process selection. The control of coking wastewater pollution should be based on the whole process from source control to end-of-pipe treatment. The source control and pretreatment play an important role in reducing the biochemical system load. The trends of biological treatment technologies,such as biological denitrification,biological fluidized bed,immobilized biotechnology and microorganism technology,etc.,were introduced. It was pointed that the selection of deep treatment processes should consider the characteristics of effluent and the reuse requirements.
