PROBLEM TO BE SOLVED: To provide a water treatment system which uses a reverse osmosis membrane device and can effectively use waste heat of a blower.SOLUTION: The water treatment system of the present invention includes: a biological treatment tank which biologically treats organic wastewater; solid-liquid separation means which separates the biologically treated water obtained by the biological treatment tank into its solid and liquid components; an aeration device which is disposed in the biological treatment tank; a blower device which is connected to the aeration device; a reverse osmosis membrane device in which the separated treated water obtained by the solid-liquid separation means is subjected to desalination treatment; and a heat exchanger which exchanges heat between the thermal fluid produced by driving the blower device and the separated treated water.SELECTED DRAWING: Figure 1 |
