油田废水排放标准适应性研究与探索

The Adaptability Study and Exploration of Oilfield Wastewater Discharge Standards

文章对油田外排废水中的石油类、COD_(Cr)等第二类污染物的排放标准进行分区、分级划定的研究,同时选择对西部干旱区生态环境有重要影响作用的总盐指标排放标准进行分区分级研究,为新疆油田公司实施"分区保护、分级防治、分类管理"提供科学依据。研究成果在石西油田、六九区大沙河排放口等地进行试点应用,为最终实现油田环境保护与经济发展双赢提供有益的借鉴。

This article conducts zoning and grading studies on discharge standards of the second-class pollutants in oilfield wastewater such as oil and COD_(Cr) and on emission standards of the total salt indicator which has a great impact on the ecological environment in western arid areas.It provides a scientific basis for the implementation of'zoning protection,grade control and category management'in Xinjiang Oilfield Company.The research result is under the pilot application in Shixi Oilfield and Dashahe discharge of Liujiu Area and it provides useful lessons for oilfield environmental protection and economic development.
