Underground water treatment method and treatment system

The invention provides an underground water treatment method and system, and belongs to the technical field of water treatment. According to the clean water storage time and the clean water storage amount, the clean water preparation time is controlled, in the normal state, the clean water storage amount can meet the water supply amount of rural residents within a period of time, and when the clean water storage amount is too long or the clean water storage amount cannot meet the water supply amount of the rural residents, residual clean water is emptied, and fresh clean water is prepared. Therefore, on one hand, intermittent operation of related water treatment equipment is realized, and the equipment is operated at a proper working load in the operation process, so that the energy consumption of the equipment is reduced, the water supply cost is reduced, and the loss of the water treatment equipment is reduced. And on the other hand, the problem of clean water deterioration caused by long-term storage of cl
