胜利油田天鹅湖水源地水质演变规律及其保护

Water quality variations and protective measures of Swan Lake water source region of Shengli Oilfield

通过对天鹅湖水环境质量现状的调查、监测,天鹅湖供水水源地已不能达到饮用水标准。查明了天鹅湖受污染的主要原因,分析了天鹅湖年内及多年来的水质演化趋势,揭示了天鹅湖多年引黄水量及其水质动态变化规律。最后提出天鹅湖水环境保护措施:只有从污染源控制、增加引黄水量、引黄次数、补源改良、宏观上加强管理控制和建立预警监控系统等多方面着手,才能保证天鹅湖水源地可供水量及供水水质,真正发挥胜利油田后备供水水源地的功能。

It was found out that the source region of the Swan Lake can not meet the drinking water standard by investigation and monitoring about current situation of water environment. The main causes of water pollution were pointed out. The changes of water quality this year and in recent years were analyzed and the dynamic rules between water quality and water diversion from the Yellow River were revealed. Finally, water environmental protective measures for the Swan Lake were proposed. It was pointed out that only by controlling the pollution sources, increasing water volume transferred from the Yellow River and water diversion frequency, improving the water quality of water transferred from the Yellow River, strengthening management control in policy, and establishing an early-warning and monitoring system, can the available water quantity and the quality of water supply be guaranteed, and the Swan Lake can be the standby source region for water supply of Shengli Oilfield.
