The membrane treatment technology has a better treatment effect now, but the membrane treatment technology has high investment costs, high maintenance and operation costs, and high requirements for membrane regeneration, which makes it difficult to promote in remote rural areas.

[0003] Chinese patent application 202122530612.X discloses a rural drinking water purification treatment device, a water treatment device and method for groundwater with excessive iron, manganese, fluorine and arsenic. The water treatment method adopts the process flow of "aeration → baffle oxidation reaction → inclined tube sedimentation → upward flow filtration → aeration → downward flow filtration" to treat groundwater with excessive iron, manganese, fluorine and arsenic, but the process flow is long and the structure is complex, which is not convenient for ordinary rural residents to disassemble and repair. In addition, by setting up chlorination disinfection facilities above the disinfection and clear water tank for disinfection, chemical residues are easily caused, which is easy to produce secondary pollution. Chinese patent application 201410128611.4.X discloses an oxidation adsorption filtration integrated drinking water arsenic removal system, which involves a drinking water arsenic removal device, which uses an organic combination of oxidation, adsorption, filtration and other methods for treatment. The total arsenic content of the effluent treated by this drinking water arsenic removal system can be reduced to 0.006 mg / L, ensuring the safety of drinking water quality, but the technology has problems such as high operating cost, high maintenance requirements and low treatment efficiency.
