| Abstract: | This article describes the results of removing fluorous anion from industral wastewater by chemical precipitation, chemical coagulation, chemical precipitation-coagulation and adsorption. The properties of chemical precipitants and coagulants used to remove fluorous-anion were contrasted and the influence of some factors such as pH, Ca/F, AI/F and tempreture were diseused and analysed. According to the experiments, it can be seen that CaCl_2 is better than CaO as the chemical precipitant and the chemical precipitation-coagulation is better than others in removing fluorous-an-ion. pH, Ca/F, Al/F, tempreture have distinct effect on outcome of removing fluorous anion from industral wastewater, so pilotplant tests are necessary to develop the optimum process. |
