Abstract
Raw water is made to pass through a raw water supply pipe by opening on-off valves, and by closing on-off valves. Oxygen is supplied to the raw water in the raw water supply pipe by opening an on-off valve of an oxygen supply pipe. The resulting raw water containing organic matter and oxygen passes through the raw water supply pipe and enters a catalyst-packed column, thereby contacting a platinum-group metal catalyst onto which hydrogen is adsorbed. This causes the organic matter in the raw water to contact the platinum-group metal catalyst under the presence of dissolved oxygen and hydrogen which is adsorbed onto the metal catalyst. Accordingly, the organic matter in the water to be treated can be easily removed at high efficiency and with low energy consumption.
