<p><P>PROBLEM TO BE SOLVED: To provide water treatment equipment that combines a reaction vessel utilizing granular active carbon or the like as a microorganism carrier with an immersion membrane separation unit to materialize compactness, energy saving and high degradation efficiency, and to provide a method of water treatment using the water treatment equipment. <P>SOLUTION: In the water treatment equipment, a reaction vessel adapted to aerate water to be treated with the use of the microorganism carrier is integrated with a membrane separation vessel equipped with the immersion membrane separation unit capable of membrane separation of the treated water from the reaction vessel. The water treatment equipment is characterized in that the reaction vessel and the membrane separation vessel are divided from each other by a first partition with an open lower end part and are communicated to each other by the open part, that the reaction vessel is divided by a second partition with open upper end and lower end parts into a pre-stage region provided with a first air diffuser in the lower part and a post-stage region adjacent to the membrane separation vessel via the first partition, and in that the bottom of the reaction vessel is inclined so that the height thereof is increased as approaching the membrane separation vessel from the pre-stage region. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
