Study on Stability of the Water Quality of Purified Produced-Water in the Oilfield of Northern Shaanxi

Abstract:

By means of analysising the characteristics of oily-sewage, the treatment process, the sewage stability characteristic of each device, It is evaluated of the stability of treatment process and pointed out the problem in the systemsof water treatment process. The results show that through the method of reducing the particle size of the filter media, optimizing the pharmaceutical system, as well as strengthen the management of the processing system. The suspended solids content, oil content, total iron content of sewage station effluent quality has reduced form 40mg/L~60mg/L、150~170mg/L,15.56mg/L~17.44mg/L to 0.7~0.9mg/L (≤ 1.0mg/L), 2.0~4.3mg/L (≤ 5mg/L), 0.09~0.32mg/L (≤ 0.5mg/L) fromexceed standard before improvement, reaching the reinjection standard.
