<P>PROBLEM TO BE SOLVED: To provide an organic material-containing water treatment method by which a flux is maintained at a high level for a long period of time by effectively suppressing the blocking of a reverse osmosis membrane. <P>SOLUTION: The organic material-containing water is subjected to a biological treatment by a biological treatment apparatus 1 and is subjected to a flocculation treatment by adding a flocculant in a flocculation treatment apparatus 2 and is then subjected to a solid-liquid separation and is filtered in filtration equipment 3. The substances clogging the reverse osmosis membrane are adsorbed and removed by calcium phosphate in an adsorption removal column 4a packed with the calcium phosphate and the salts are separated through membranes by a reverse osmosis membrane apparatus 5. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
