The shortage of water resources and water pollution in China seriously threaten the safety and health of drinking water of human beings. The acidic wastewater is a wastewater which has strong acidity and is rich in SO 42-and various heavy (like) metal ions (Fe, Mn, Cr, As and the like), and the effective treatment of the acidic wastewater becomes one of the key problems of the comprehensive treatment of the ecological environment. The water is usually discharged into nearby rivers, lakes and other water bodies, so that the pH value of the water body is changed, the growth of certain microorganisms in the water body is inhibited, and the purification of the water body is hindered.
