The characteristic of arsenic containing wastewater in sulfuric acid production has been studied. Based on oxidization-neutralization and physicochemical reaction theory,the arsenic containing wastewater is treated by using H 2O 2 and waste NH 3·H 2O. The wastewater is purified deeply by using self made soluable Ca Fe synthetic flocculants. The result shows that the wastewater discharged can completely meet the national discharge standards. The technical process is simple and feasible, with less sludge, less investment,convenient operation and easy management. Thus a new way to treat arsenic containing wastewater is provided.
