Abstract

Hydropower construction projects have the characteristics of large construction scale, short construction period, large wastewater discharge and difficult management, and the waters near hydropower stations may be close to environmentally sensitive areas such as scenic spots and historic sites and forest reserves. If construction wastewater is not treated and discharged, it will have great impact on the environment. Based on the engineering analysis of hydropower construction projects, this paper understands that the construction waste water mainly consists of stone aggregate washing waste water and concrete mixing system washing waste water. According to the principle of coagulation and sedimentation and the characteristics of engineering waste water, the construction waste water is treated by physical and chemical methods and combined with coagulation and sedimentation process, so as to reduce or eliminate negative environmental impact, avoid environmental risks and control pollution.
