Abstract:

The suspended solid index of oil-field wastewater injection quality is generally determined by gravimetric method, but this method has evident disadvantages, such as complex operation and long determination time. The experimental results show that the concentration of suspended solid in water and its absorbance have very good relativity (correlation index R²=0.998 6), and the errors measured can be controlled by less than 5%. Spectrophotometric method used for the determination of suspended solid in oil-field wastewater is characterized by simple operation and short determination time. Therefore, it is applicable to monitoring the running status of wastewater treatment systems.

Key words: oil-field wastewater, suspended solid, spectrophotometric method, gravimetric method

摘要：

油田注水水质中悬浮物指标普遍采用重量法测定，但重量法存在操作复杂、耗时长等不足。经试验，水中悬浮物浓度与其吸光度具有良好的相关性（相关指数R²=0.998 6），测量误差可控制在5%以内。采用分光光度法测量油田污水中悬浮物浓度操作简单、耗时短，可用其监测污水处理系统的运行状态。
