Abstract:

Water quality and primary problems in the wastewater treatment of Changqing Oil Field and Yanchang Oil Field are analysed.Suitable techniques and agents for treating the wastewater are put forward through tests.The treated effluent can meet the injection water quality standard and recycling water quality standard.At the same time,the ways to the synthetic utilization of wastewater is brought forward,settling the problems of the waste of water resource and environment pollution in the process of developing low-level penetrative oil fields in Northern Shaanxi.
