<p>PROBLEM TO BE SOLVED: To establish a method in which filter medium is transferred from a filter medium storage tank to a filter medium separation tank at a mixed ratio with transferring water to circulate and use it in a moving bed filter using floating filter medium. SOLUTION: In a moving bed filter using floating filter medium, a filter medium storage tank 10 and a filter medium inflow valve 14 are installed in the upper part thereof and a discharge pipe 9, a discharge port 12, and an adjusting tool 11 are installed in the storage tank. A filter medium transferring water pump 4 for sending transferring water, a transferring water pipe 5, a filter medium transfer valve 15, and a filter medium transfer pipe 16 are connected to form a transfer line. And by a discharge port adjusting tool 11, a mixed ratio of the filter medium to the transferring water is determined, and while the transferred quantity is kept constant, the filter medium is transferred from the storage tank 10 to a lower filter medium separation tank 21.</p> |
