Salinization Mechanism of Water from the Yellow River in Bei-Da-Gang Reservoir & Control Measures

Qishan Wang

Abstract

The water diversion project of the Yellow River to Tianjin (also called Yin-Huang-Ji-Jin Project) is an effective measure to resolve water resources shortage in Tianjin City. Bei-Da-gang reservoir is the only regulating reservoir for this project. The water gets salted during being stored in Bei-Da-Gang Reservoir and chlorine ion concentration goes beyond Ⅲ level of the National Standard of Surface Water Quality. Based on mass transfer theory, the water salinization mechanism is analyzed. It is concluded that the water salinization mechanism is mainly affected by the physical geography and weather condition in Bei-Da-Gang Reservoir area. Some measures to retard the speed of the salinization are proposed in the article.
