<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing reclaimed water for preventing a problem in which fine solid matters which flow out without sedimented by gravity inside a final sedimentation pond increase loads on a filter membrane surface for manufacturing reclaimed water by a simple and low-cost method and stably obtaining the reclaimed water from sewage. <P>SOLUTION: The method of manufacturing the reclaimed water is provided for obtaining the reclaimed water by membrane filtration of sewage secondary effluent, and the method includes a process of leading the sewage secondary effluent flowing out from the final sedimentation pond 3 provided in the post stage of a biological treatment tank 2 to a non-agitated sedimentation tank 4, sedimenting the fine solid matters included in the water to be treated by gravity and removing them from the water to be treated. <P>COPYRIGHT: (C)2010,JPO&INPIT |
