Abstract

The invention discloses a cofferdam construction wastewater treatment process comprising the steps: carrying out magnetic medium coagulation separation precipitation treatment on wastewater, adding acoagulant aid into the wastewater before magnetic medium coagulation separation precipitation, and carrying out pre-precipitation treatment on the wastewater. The process is suitable for treatment ofcofferdam construction wastewater with large water volume and large water volume and water quality fluctuation, the impact load resistance of a wastewater treatment system can be improved, and cofferdam wastewater can be effectively treated under the working conditions of large wastewater volume and water quality fluctuation.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a cofferdam construction wastewater treatment process. Background technique [0002] The country is rich in water resources. The development purpose of hydropower stations is mainly to generate electricity, and to store water and energy, share the flood control tasks in the middle and lower reaches of rivers, and improve the functions and functions of river channels. The economic benefits are significant. During the construction of the hydropower station, the volume of construction wastewater in the cofferdam area is large and fluctuates greatly, and the concentration of suspended solids is as high as 15,000 mg / L, which is mainly composed of inorganic substances such as rock powder, sediment, and cement particles. Periodicity, the wastewater quality fluctuates greatly. [0003] The existing published patent name is "a high-efficiency wastewater sedimentation system ...
