| Abstract: | An orthogonal experiment was conducted to investigate the influence of three key factors, including dosages of coagulant, precipitant and adsorbent, on the efficiency for removing Ca2+ and COD from fluorspar flotation wastewater by adopting coagulation-sedimentation and adsorption approach. The results show that best wastewater treatment effect can be actualized with the dosages of coagulant CSP-12, precipitant Na2CO3 and adsorbent activated carbon respectively as 12 mg/L, 900 mg/L and 200 mg/L. Under this optimal condition, the removal rates of Ca2+ and COD can reach 91.26% and 60.54% respectively. |
