摘要:

石油化工园区产业结构的多元化及产排污的非规律性导致其污水成分复杂且水质水量波动大,加之日趋严格的排放限制以及对废水回用及资源化的要求,使得污水处理成为园区普遍面临的环保压力。基于对石油化工行业污水特征和全流程处理技术的认知,突出强调了源头管控对污水处理系统正常运行的重要性,识别了需要重点管控的污染物并提出了纳管指标建议值和污水预处理方法,之后对在此基础上进行的园区集中处理进行了阐述。此外,对湿式氧化、臭氧催化氧化、生物脱氮等典型处理技术和应用案例进行了分析总结,对未来污水处理由“去除”向“回收”转变的趋势作了进一步展望,以期为石油化工园区污水资源化处理提供参考。

Abstract:

Due to the diversification of industrial structure and the irregularity of production pollutants and discharge pollutants in petrochemical parks,the wastewater composition is complex and the quality and quantity fluctuate greatly. Coupled with the increasingly stringent discharge restrictions and the requirements for reuse and recycling,wastewater treatment has become a common pressure on environmental protection in the park. Based on the understanding of the wastewater characteristics and the whole process treatment technology of petrochemical industry,the importance of source control to the normal operation of wastewater treatment system was highlighted. Key pollutants need to be controlled were identified,and the suggested value of admission index and pretreatment method were put forward. Afterwards,the centralized treatment of the park based on these was elaborated. Besides,the typical treatment technologies and cases such as wet oxidation,catalytic ozonation and biological denitrification were analyzed and summarized. The trend of wastewater treatment from “removal” to “recovery” in the future was further prospected,which hoped to provide reference for the resource treatment of wastewater in the petrochemical park.

Key words: petrochemical park, sewage full process treatment, sewage resources
