| Abstract: | By the two-stage removal technology of adding calcium hydroxide, then adding Ca 2+ and phosphoric acid into fluoric wastewater, fluorine can be taken out, and the optimum of technology conditions are obtained. The results show that by controlling right pH, amount of Ca 2+ and phosphoric acid, reaction time, reaction temperature, the stirring power and amount of the flocculant accelerator, the concentration of fluorine in wastewater can be reduced down to 5 mg/L after reaction, so that it can meet the national standard of discharge. |
