on the results of the removal of heavy metal ions from metal smelting wastewater, it can be concluded that the prepared 3D graphene/MgO composite is an effective and potential adsorbent. Key words... due to the increasing development of industries. Especially, the emission of untreated wastewater from smelter containing heavy metal ions was one of the most serious problems. Heavy metal ions......
, Pb and Zn) were investigated in the 17 operating municipal wastewater treatment plants (WWTPs) and compared with those in four main activated sludge processes. Significant differences of heavy metal... treatment process.Key words:wastewater; heavy metal; removal efficiency; treatment process; activated sludge processes......

brings more and more threats to environment. So, it is very imperative to research on such wastewater. When the ammonia exists in nickel wastewater, nickel ion and free ammonia can form metal complex ion, which makes it difficult to treat. At present, some treatments to this kind of water merely concern with the heavy metal pollution, neglecting the ammonia pollution [2-5]; some aim......

of the electroplating industry in China has resulted in an increase of electroplating wastewater containing heavy metal ions, toxic and nonbiodegradable organic pollutants discharged in the environment. For the development of electroplating industry, powerful wastewater treatment processes are necessarily employed. In recent decades, the control technique of heavy metals in electroplating wastewater [1-4......
