, during the initial stage of treating real wastewater with the tungsten residue-based ceramsite, the removal of heavy metal ions can be improved through enhancing agitation of the wastewater solution... decreases. The adsorption capacity increases with the increase of initial pH of the solution. The ceramsite can be applied as an effective adsorbent for heavy metal-containing wastewater treatment......
of the relative deviations between the simulation value and the field survey result are within ±10%. Key words: sediment; heavy metal pollution; re-release rate; numerical simulation 1 Introduction... pollutants, the sediments will cause secondary pollution to the overlying water in the form of a new source [11]. Therefore, researches focusing on the release of heavy metal pollutants in sediments......
