摘要
焦化废水溶液性质复杂,经生化处理后,仍残留多环芳烃、苯、胺等难降解有机物,不仅对生态环境造成污染,也会对水回用构成技术障碍.随着环保要求的日益提高,亟需强化焦化废水的深度处理工艺,实现焦化废水的"零排放".本文根据焦化废水生物出水的性质特征,选择混凝沉淀、活性炭吸附和臭氧氧化这三种物化技术来分质去除生物出水中的有机物,考察物化技术协同机制及其工艺有效性,为焦化废水深度处理的工艺路径提供优选方案.
Abstract
The properties of coking wastewater solutions are complex.After biochemical treatment,persistent organic compounds such as polycyclic aromatic hydrocarbons,benzene,and amines remain,which not only pollutes the ecological environment but also poses technical obstacles to water reuse.With the increasing environmental requirements,it is urgent to strengthen the deep treatment process of coking wastewater and achieve"zero discharge"of coking wastewater.This article selects three physical and chemical technologies,namely coagulation sedimentation,activated carbon adsorption,and ozone oxidation,based on the characteristics of biological effluent from coking wastewater to remove organic matter in biological effluent.The synergistic mechanism of physical and chemical technologies and their process effectiveness are examined to provide optimal solutions for the deep treatment process of coking wastewater.
