摘　　要：炼油含盐污水采用预处理、生化处理、深度处理流程,污水在预处理单元实现除油、去除部分悬浮物和均质调节,达到生化单元进水水质要求;在生化单元通过厌氧水解酸化、A/O/O工艺,实现对炼油含盐污水中难降解物质的小分子化、提高可生化性以及硝化、反硝化作用去除总氮;深度处理单元通过高效沉淀、反硝化、臭氧催化及生化协同作用进一步除去炼油含盐污水中存留的污染物质,提高出水水质。The process of pretreatment,biochemical treatment and advanced treatment is adopted for refinery saline wastewater.Oil removal,partial suspended solids removal and homogenization adjustment are realized in the pretreatment unit to meet the inlet water quality requirements of biochemical unit.Anaerobic hydrolysis and acidification and A/O/O processes are adopted in the biochemical unit.The advanced treatment unit can further remove the remaining pollutants in the refinery saline wastewater by means of high efficiency precipitation,denitrification,ozone catalysis and biochemical synergy,so as to improve the effluent quality.
