Abstract: A near-zero maintenance integrated purification device for drinking water supply of villages and towns and a method for treating source water using this device are provided to solve the multi-pollution problems caused by microorganisms, turbidity, iron, manganese, taste and odor, and organic matter in the drinking water sources of villages and towns. The device includes a small-spacing folding plate speed sink regulating water tank, a small diameter tube reactor, a granular active carbon (GAC) slow-speed filter tank, a gravity-driven ultrafiltration membrane tank and an ipsilateral U-turn corridor clean water tank. The near-zero maintenance integrated purification device is applicable to different types of water sources (e.g., groundwater, lake water, reservoir water, spring water, snowmelt water, cellar water and rain water, etc.), and could efficiently remove kinds of pollutants, improving the biological and chemical safety of drinking water.
