| Abstract: | The treatment of alkaline wastewater with high concentration of arsenic has been studied We put forward the technology of oxidation_flocculation to overcome the demerits of conventional methods for removing arsenic The results showed that the effect of removing arsenic by oxidation flocculation is remarkable The content of arsenic is under 0 5 mg/L after the wastewater treatment. It measures up the national standards of letting water The best technical conditions are that pH is 6-7, the dosage of H 2O 2 is 2 5%, oxidation time is 10 minutes, the dosage of Fe 2(SO 4) 3 is 2 5 g/L, the dosage of PAM is 11 25 mg/L |
