1. Experimental purpose and principle:
After crude oil is extracted from Liaohe Oilfield, it is refined by the nearby refinery, and wastewater is discharged from distillation, quenching, superposition, coking and other production equipment and oil tank areas. The oil in the wastewater is mostly in a suspended or emulsified state in the water. In addition to oil, the wastewater also cont*ns sulfides and phenols. In addition, alkaline wastewater is discharged during the alkaline washing process of the oil. Wastewater
treatment in refineries generally includes oil removal, sulfur removal, and phenol removal. This equipment is designed according to the pilot experiment process of Liaohe Oilfield. The process is reasonable and the effect is good, so that students can achieve the following goals after learning: 1. Understand the process flow and technical parameters of this equipment; 2. Deepen the understanding of the basic concepts of the experiment and improve theoretical and practical knowledge; 3. Through operation, the oil removal rate, COD, BOD5, and SS removal rates can be measured to improve operating skills. 2. M*n technical indicators and parameters: 1. Ambient temperature: 5℃～40℃ 2.
