<p><P>PROBLEM TO BE SOLVED: To provide a synthetic treatment apparatus for the blue-green algae and microcystine capable of rapidly and economically purifying a closed water area where water bloom occurs and capable of preventing the secondary pollution of environment, the disturbance of an ecosystem and the propagation of water bloom caused by treatment. <P>SOLUTION: The treatment apparatus 50 for the blue-green algae and microcystine is installed in a state floating in a polluted water area 5 by a plurality of the float members 52, etc. provided to the outer periphery of a decomposition treatment tank 54 and internally filled with a large number of bottom sludge fixing carriers 56, etc. for inclusively fixing the bottom sludge of the polluted water area 5. When raw water of the polluted water area 5 flows in the decomposition treatment tank 54 from introducing ports 58, etc., it is mixed with and brought into contact with the bottom sludge fixing carriers 56, etc. to be subjected to decomposition treatment. Treated water is taken in an intake port 66 after the bottom sludge fixing carriers 56, etc. by the net 68 of an air lift pipe 60 and raised by the aeration air of an aerator 62 to be returned to the polluted water area 5 from lead-out pipes 64, etc. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
