Research conclusions:(1)Water Qinling tunnel construction waste is inorganic suspended polluting water, the lower the concentration of organic pollutants. (2)Under normal circumstances，No. 6 adit average daily waste water is about 17 867 m3/ d，the maximum amount of water is 35 734 m3/d; under the 7th adit normal average daily wastewater is about 7 826 m3/d，the maximum amount of water 15 730 m3/d. (3)For the Qinling Tunnel of wastewater quality paper proposes a “coagulation+sedimentation+adsorption+filter” as the core of the treatment process，the treated water can meet the “Surface Water Environmental Quality Standard”(GB 3838-2002)in Ⅱwater indicators.(4)Qinling tunnel construction waste to the “coagulation+sedimentation+adsorption+filter” research as the core processing technology，adapted to the highway，railway construction is widely used integrated treatment of wastewater tunnel and promote and protect the ecological environment.
