摘要：

对加西原油加工过程产生污水的性质进行分析,该污水具有pH大、硫化物含量低、氨氮含量低、含油量低、COD含量高的特点。在污水处理场原有设施上,通过调节pH、增加絮凝剂投加量、增加生化池葡萄糖投加量、调节生化池温度等措施,使加西原油加工期间所产生的污水全部达标排放。

关键词: 高硫原油加工废水, 气浮, 生化处理

Abstract:

Based on the processing of Western Canada crude oil in a refinery,the properties of the industrial wastewater generated during the processing course are analyzed.The wastewater is characterized by high pH,low sulfide content,low ammonia-nitrogen content,low oil content,and high COD content.It is found that by using the original facilities in the wastewater treatment plant,all of the wastewater generated during the course of high-sulfur Western Canada crude oil processing reaches the emission standard,through adjusting the pH,increasing flocculent dosage and glucose dosage in biochemical pool,and adjusting the temperature of biochemical pool.

Key words: high-sulfur crude oil processing wastewater, flotation, biochemical treatment
