Research on drinking water purification technology in rural area of Jianghan Plain

Aiming to the surface water pollution situation and drinking water-induced disease in rural area of Jianghan Plain, the rural water purification scheme and technology were designed to meet the basic drinking water demand of rural populations.  The designed technology considered both the tight-structure demand of integrated equipment and the water purification function; the ozone pre-oxidation and coagulating sedimentation are selected as pre-treatment, the reliable quartz sand filtering are selected as regular treatment and the ultraviolet sterilization and membrane separation are chosen as advanced treatment. Based on the technical design of water treatment, a set of hydro-cyclone and enhanced coagulation equipment is designed, which integrates mixing, flocculating and settling. As a modularization design, the water purification system is tight in structure, convenient in installation and use, and provides a new method for the purification of drinking water in rural areas.
