The invention discloses a weak alkaline treatment method for natural deep-well underground water. The weak alkaline treatment method comprises the following steps: leading out deep-well underground water from a deep well; after leading out the underground water, enabling the water to enter an aeration device and carrying out aeration so as to enable the water to be in sufficient contact with purified air and remove harmful gas including hydrogen sulfide and the like in the water; enabling the aerated water to enter a primary filter for removing surplus salt in the water; after passing through the primary filter, enabling the water to enter a fine filter provided with a micro-pore filter element; filtering residual trace suspended particles, colloids and microorganisms in the water through a physical method; then enabling the water to enter a nano-filter for filtering harmful heavy metal ions in the water; producing small-molecular-group water through a small molecular water production device.
