Document Type and Number:
Japanese Patent JP2883462
Kind Code:
B2
Abstract:
PURPOSE:To maintain the quality of treated water at a specified value by detecting the change in the treating conditions of bioactive carbon and controlling the stagnation time i the bioactive carbon part even if the above-mentioned conditions are changed by the fall of the water temp. CONSTITUTION:This system has the plural bioactive carbon tank devices 2a to 2d which treat the treated water 4 supplied thereto and sends this water to the ensuing stage, water quality detecting sections (dissolved oxygen meters 12, 21) which detect the difference between the quality of the treated water 4 supplied to the respective bioactive carbon tank devices 2a to 2d and the quality of the treated water 4 sent to the above-mentioned ensuing stage and connection determining sections (inflow valves 13a to 13d, outflow valves 17a to 17d, connecting pumps 18a to 18c, connecting inflow valves 19b to 19d) which connect the above-mentioned bioactive carbon tank devices 2a to 2d in series or in parallel in accordance with the results of the detection of the above- mentioned water quality detecting sections.
