| The characteristics of shale gas produced water were analyzed by ion chromatography, GC MS,ICP and other analysis methods and the basic physico chemical properties were studied. COD, SS, ammonia nitrogen, petroleum and chloride were the main pollutants, their concentrations varied greatly with time and changed with location in some rule. The most of organic compounds in the shale gas produced water were alkanes, while cyclohexanol, aniline, naphthalene, volatile organic compounds and semi volatile organic compounds such as monocyclic aromatic hydrocarbons, phenols, polycyclic aromatic hydrocarbons and phthalates were in small amount. |
