- 摘要：针对炼油企业化工助剂对污水处理系统的影响，系统调研了某公司蒸馏、焦化等装置的助剂（原油破乳剂、中和缓蚀剂等）使用参数（投加量、频次及入水系统路径），结合水样（COD、pH值、氨氮、油含量）检测与上游油田助剂溯源分析，建立了企业—油田药剂数据库。研究发现，焦化/蒸馏装置电脱盐排水可生化性差（COD去除率 <5%），而加氢装置污水可生化性优异（COD去除率>80%）。据此提出“高级氧化预处理 + 生化处理”的分级处理工艺，为炼油污水高效处理提供技术参考。
Abstract: In response to the impact of chemical additives used in oil refining enterprises on the sewage treatment system, this studyconducted a systematic investigation into the application parameters (including dosage, frequency, and injection pathways) ofadditives-such as crude oil demulsifiers and neutralizing corrosion inhibitors-within the distillation and coking units of a selectedenterprise. By integrating water sample analyses (measuring COD, pH, ammonia nitrogen, and oil content) with traceabilityassessments of additives from upstream oil fields, an enterprise-level oilfield reagent database was established. The findingsrevealed that wastewater from the electric desalting processes of coking / distillation units exhibits poor biodegradability (CODremoval rate <5%), whereas wastewater from hydrogenation units demonstrates excellent biodegradability (COD removal rate >80%).Based on these results, a tiered treatment strategy combining "advanced oxidation pretreatment followed by biochemical treatment"is proposed, offering a technical reference for the efficient management of oil refining wastewater.
