Summary:PROBLEM TO BE SOLVED: To provide a rain water cleaning method for cleaning rain water for utilizing the rain water as drinking water as well as utilizing the rain water as a resource of water for the whole daily life, by collecting the rain water as much as possible when rainfall is small and cleaning it for use and reserving excess rain water when rainfall is large and using it in the case of drought, and an apparatus. SOLUTION: The rain water cleaning method and apparatus can efficiently make the rain water into inexpensive drinking water to stably supply in effective utilization of a water resource. The method comprises the steps of passing the rain water collected from a roof through a trough through a filtration column constituted of crushed granite, then passing the rain water through an air blow tank retaining a highly electrical conductive bamboo charcoal grain, thereafter passing the water through a column retaining a highly electrical conductive bamboo charcoal block piece twice and then passing the water through a primary activation treatment tank retaining the highly electrical conductive bamboo charcoal block piece treated by the raw water of pie water and activated ceramic, thereby changing the rain water into water suitable as the drinking water. The method further comprises the step of secondarily passing the water through a tank retaining the activated ceramic after filtering the water by a metal wire mesh with 100-150 meshes as the final stage treatment as drinking water. The apparatus comprises a series of treatment tanks. COPYRIGHT: (C)2006,JPO&NCIPI
