The arsenic-containing shale gas wastewater has high salinity and complex   composition.In this study, capture separation and deep adsorption composite processes were used to remove heavy metal arsenic from shale gas wastewater.The experimental results showed that the maximum removal rates of CODCr, SS, TDS, and As from low concentration arsenic-containing shale gas wastewater were 33.5 %, 95.3 %, 0.36 % and 80 % respectively.As for the higher concentration of arsenic-containing shale gas wastewater, the maximum removal rates of CODCr, SS, TDS, and As were 34.9 %, 96.4 %, 0.97 % and 97.8 % respectively.The heavy metal arsenic from low and high concentration of arsenic-containing shale gas wastewater could be extensively removed by deep adsorption and consequently be in compliance with the water quality standards of class III inEnvironmental Quality Standards for Surface Water(GB 3838-2002).This novel method for the treatment of arsenic by capture separation and deep adsorption composite processes provides the basic data and technical support for arsenic removal applications from shale gas wastewater.
