| Abstract: | Atreatment for acid high fluoride wastewater from a polycrystalline silicon factory by coagulation and precipitation was carried out.The process was used lime as neutralize precipitation,ferrous sulfate as coagulants and polymer PAM as occulant.It is found that the optimum experimental conditions for 150.00 mL wastewater,adding dosage of CaO,FeSO4 and PAM is 33.3g/L,6.7g/L and 667mg/L,respectively.The concentration of wastewater can be reduced to below 10.00mg/L and meets the national drainage standard. |
