1、化工环保·124·ENVIRONMENTALPROTECTIONOFCHEMICALINDUSTRY2016年第36卷第2期不同类型清水剂处理油田含聚污水的效果对比翟磊,王秀军,靖波,檀国荣(1.海洋石油高效开发国家重点实验室,北京100028;2.中海油研究总院,北京100028)[摘要]考察了阳离子型CWC一14、非离子型NQS—O1和阴离子型AQS一083类清水剂对油田含聚污水的处理效果,对比了它们的作用特点和絮体性能。实验结果表明:在清水剂加入量350mg/L、处理温度65℃、搅拌转速30
2、0r/min、搅拌时间5min的条件下,CWC一14、NQS一01和AQS一08对含聚污水的除油率分别为98.8%、98.0%和99.4%;NQS一01受处理温度、搅拌条件影响较大;CWC一14受污水中聚合物质量浓度影响最大。清水剂的絮体特点与其作用机理有关,CWC一14的絮凝速率最快,起效时间最短,絮体呈黏性大块状;NQS一01的絮凝速率最慢,起效时间最长,絮体呈浮油状;AQS一08的絮凝速率和起效时间适中,絮体呈松散状、流动性好。对比结果表明,非阳离子型清水剂可有效避免油田含聚污水处理过程中的
