摘要
石化污水主要是石化企业在加工生产不同石油产品过程中所产生的一类典型的工业废水。在面对原油劣质化和工艺技术限制等诸多实际问题时，石化污水的组成复杂性、生物高毒性等特点与目趋严格的环保要求之间的矛盾显得尤为突出。因此，在石化行业污水水量和处理难度日益增高的新形势下，对石化污水的来源、分类及组成的全面认识和综合分析对于污水处理工艺的相关改进和石化企业的可持续发展具有十分重要的意义。
Petrochemical wastewaters are a typical category of industrial wastewaters during the processing of different oil products Confronting many practical problems, such as the quality deterioration of crude oil and technical constraints, the conflict between the high toxicity of petrochemical wastewaters and the increasingly stringent environmental requirements becomes particularly intense. Therefore, under the new situations which the quantity and treatment difficulty of petrochemical wastewaters are growing quickly, the overall understanding of petrochemical wastewaters＇ origin, classification and composition is of great importance for the improvement of sewage treatment processes and the sustainable development of petrochemical enterprises
