Abstract: PROBLEM TO BE SOLVED: To economically purity river water while using economical coal as a purifying source by immersing coal accumulation prepared by packing net bags with coal in river and purifying the river water by bringing into contact with the coal. SOLUTION: Strings 12 are passed through coal accumulation 10 prepared by packing net bags 16 with coal 14 and both ends of strings 12 are fixed in the banks of a river in such a manner that the coal accumulation 10 are immersed in water. Consequently, river water is purified by being brought into contact with coal 14. In this case, the coal accumulation 10 should be installed in relatively high density and a large number of strings 12 are installed at 50m or 100m distances. Floats 18 are preferably installed in both ends of net bags 16 and the immersion depth of the coal accumulated bodies 10 are adjusted by adjusting the floats 18. Moreover, the coal 14 to be packed is formed to be spherical just like charcoal balls, so that coal 14 itself is enabled to self- rotate by the flow of the river water and the purifying capability can be improved.
