<P>PROBLEM TO BE SOLVED: To provide a seawater desalination system and seawater desalination method which can produce drinking water from seawater and which can increase industrial water and which attains inexpensive water desalination cost. <P>SOLUTION: The seawater desalination system S for obtaining industrial water and drinking water from seawater and sewage water, includes a purification device 1 which eliminates active sludge from sewage water to purify the sewage water, a first RO membrane 2 which eliminates salt from water transmitted through the purification device 1 so as to be included in first concentrated water s6 and generates industrial water s1, a UF membrane 3 which transmits seawater to eliminate particles in the seawater, a second RO membrane 4 which eliminate the salt of treatment water s5b transmitted through the UF membrane 3 so as to be included in second concentrated water s7 and generates drinking water s2, a stirring device 5 which stirs the second concentrated water s7 which is eliminated at the second RO membrane 4 and the first concentrated water s6 which is eliminated at the first RO membrane 2, and a third RO membrane 6 which eliminates the salt of a mixed liquid stirred at the stirring device 5 to be included in third concentrated water s9 and generates industrial water s3. <P>COPYRIGHT: (C)2013,JPO&INPIT |
