Groundwater often contain excessive iron and manganese, while long-term consumption of iron, manganese high water on the human body adversely. At higher water iron, iron smell of water, affecting the water's taste, as paper, textile, printing and dyeing, chemical and leather production water, will reduce the quality of products; washing clothes will appear yellow or brown stains stains, iron precipitate iron bacteria will grow, blocking the pipes, sometimes red water. The problems that occur with a high manganese content of water higher iron content in a similar situation, and in the industrial field, iron, manganese content in the water is too high for the device with a certain corrosion thus shortening the life of the device. According to China's drinking water quality standards, all drinking water in the iron content greater than 0.3 mg / l, the manganese content is greater than 0.1 mg / l must be decontaminated. In addition to iron and manganese equipment is mainly used in underground high-speed rail, high manganese areas with water treated in line with the national drinking water standards.
