Abstract: Tunnel construction wastewater has the characteristics of high suspended solids and high pH value, and direct discharge will affect the surrounding environment. Based on the characteristics of various sewage treatment technologies, various water treatment technologies suitable for tunnel construction wastewater quality are compared, mainly including traditional coagulation sedimentation, inclined plate sedimentation, cyclone separation, magnetic coagulation sedimentation, super magnetic separation and other water treatment technologies, aiming to provide technical support for project implementation.
Keywords: physical and chemical technology; construction tunnel wastewater; waste water treatment
