| 摘 要： | 炼厂焦化废水是一类乳化较严重的废水,本文通过室内小试筛选出阳离子型焦化破乳剂JQ-104,试验结果显示,当焦化废水含油4235.6 mg·L-1,JQ-104投加量300 mg·L-1,废水含油去除率高达95.51%;另外,pH值对其有较大影响,最佳pH值范围为6-8.将JQ-104应用于现场工艺流程,除油效果明显,处理后出水稳定,含油浓度在200mg·L-1以内,减少了污油对环境的污染.

| Abstract: | Coking demulsifier JQ-104 was selected to treat oil refinery coking wastewater. The results indicated that when JQ- 104 was used in the treatment of coking wastewater, the most suitable dosage of coking demulsifier was 300mg·L-1 and the maximal removal of oil was 95.51%, at the oil concentration 4235.6mg·L-1, and the best pH 6-8; When JQ-104 is used in production, the oil concentration of treated water was under 200mg·L-1. JQ-104 is a better coking demulsifier when used in coking wastewater treatment, which decreased environment pollution caused by wastewater. |
