Background

The water source of drinking water for rural life in China is mainly underground water, the percentage of which is 74.87%, and in many rural areas in China, the underground water source widely has the overproof phenomenon of iron, manganese and the like, wherein iron and manganese almost simultaneously exist in the underground water (well), and mainly exist in a divalent metal ionic state, and the content of the iron and manganese which are necessary trace elements for human bodies exceeds the standard in the water body, so that the quality indexes of the water body such as color, smell, taste and the like can be influenced, and chronic poisoning can be caused; meanwhile, with the 'rural implementation (sanitary standard for drinking water) rule' as an evaluation standard, the proportion of the inferior grade water with the underground water not reaching the basic sanitary safety is 45.94% in counties and regions investigated nationwide, and the proportion of the total number of bacteria and the total coliform group is highest in each detection index. Only 5.11% of households process drinking water. The water quality safety influences the health of villages, so the water quality of drinking water in rural areas in China still needs to be improved urgently.

At present, the main methods for removing iron and manganese from underground water are as follows: coagulating sedimentation, chemical sedimentation, permanganate oxidation, ion exchange, contact oxidation, microbial oxidation, and the like.
