摘要
根据符合GB 31570—2015《石油炼制工业污染物排放标准》中基准排水量要求的某石油炼制企业的废水处理与循环利用工程设置和实际运行数据,文章以酸性水汽提处理、电脱盐废水预处理、催化剂再生烟气脱硫废水处理等炼油企业点源废水分质处理工艺,全厂污水深度处理与回用和循环利用工程为主要研究对象,系统研究了石油炼制主要产排废水分质处理与循环利用的工程实践对炼油企业节水减排的贡献。
This paper focuses on the wastewater separate treatment, recycling and reuse practices carried out at a typical refinery that satisfies the prescribed benchmark effluent volume per unit crude oil in GB 31570-2015 "Emission Standard of Pollutants for Petroleum Refining Industry". Three typical sources wastewater separate treatment processes, including sour water stripping process, desalter effluent treatment, and FCC regenerated flue gas purification effluent treatment and the advanced wastewater treatment and reuse system are studied with respect to their contributions to water conservation and effluent minimization of a refinery.
