Experiment and Practice on the Wastewater Treatment in Tunnel Construction Processing

Article Preview

Abstract:

The concentration of suspended solid (SS) was confirmed as the main pollutants in wastewater from the tunnel construction processing through wastewater source and water quality in the tunnel construction processing being analyzed. The rapid wastewater treatment device was designed which combined with rotational flow sedimentation tank and flocculation reaction pool that the cement was used as flocculants. The results showed at the preliminary test that the removal efficiency of SS was above 94%. The effluent can meet the wastewater discharge standard. It was the fact that the treatment method was fast and convenient processing.
