<p><P>PROBLEM TO BE SOLVED: To provide an anaerobic tank which facilitates the maintenance and permits the space-saving, lower cost and higher quality of treated water and to provide a waste water treatment system including the anaerobic tank. <P>SOLUTION: The waste water treatment system 1 is composed of the anaerobic tank 2, a flow rate adjusting tank 3 and a denitrification tank 4 which are arranged respectively on the upstream side and the downstream side of the anaerobic tank 2 and a membrane separation tank 5 which is arranged on the downstream side of the denitrification tank 4. The flow rate adjusting tank 3 adjusts the flow rate of water to be treated supplied to the anaerobic tank 2, the anaerobic tank 2 performs anaerobic treatment and solid-liquid separation of the water to be treated, the denitrification tank 4 performs denitrification of the water to be treated returned from the membrane separation tank 5 and the membrane separation tank 5 performs membrane filtration and aerobic treatment of the water to be treated. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
