摘要： PROBLEM TO BE SOLVED: To provide a method for efficiently purifying waste water contg. salts, etc., to the extent of allowing the direct discharge of the water to rivers, etc., i.e., an efficient treatment method for the org. waste water contg. the salts. SOLUTION: This treatment method treats the org. waste water contg. the salts in the following manner: The waste water described above is subjected to a softening treatment to lower the calcium concn. therein. The water is then subjected to a removal treatment of org. matter, followed by a reverse osmosis treatment, by which the water is separated to the reverse osmosis concd. water and the fresh water. While the fresh water is recovered, the reverse osmosis concd. water is subjected to an electrodialysis treatment to separate the water to the salts concentrated water and the desalted water. The desalted water is returned into the waste water from which the org. matter is removed and which is to be subjected to the reverse osmosis treatment. A biological treatment, coagulating sedimentation treatment, sand filter treatment or precision filter membrane treatment is recommended to be used for the removal treatment of the org. matter. The salts concentrated water is recommended to be separated to the salts and moisture by an evaporation drying treatment.

摘要： PROBLEM TO BE SOLVED: To provide a method for efficiently purifying waste water contg. salts, etc., to the extent of allowing the direct discharge of the water to rivers, etc., i.e., an efficient treatment method for the org. waste water contg. the salts. SOLUTION: This treatment method treats the org. waste water contg. the salts at a high concn. in the following manner: The waste water described above is subjected to any of a biological treatment, coagulating sedimentation treatment, sand filter treatment or precision filter membrane treatment or the treatment consisting of a combination of >=2 thereof and is then subjected to a desalting treatment by a reverse osmosis membrane, by which the waste water is separated to the reverse osmosis concd. water and the reverse osmosis treated water. The reverse osmosis treated water is recovered and the reverse osmosis concd. water is subjected to a softening treatment for removing calcium and is then subjected to an electrodialysis treatment, by which the water is separated to the electrodialysis concd. water and the electrodialysis desalted water. The electrodialysis desalted water is returned again to the supply side of the reverse osmosis.
