PROBLEM TO BE SOLVED: To provide a frozen and concentrated wastewater treatment apparatus for efficiently recovering recirculated water which can be used for irrigation water, recycled waste-water or the like from wastewater (non clean water). SOLUTION: An apparatus including a supercooled water producing heat exchanger for supercooling the waste water, suspended matter removal means for removing a suspended matter in the waste water to be supplied to the supercooled water producing heat exchanger, supercooling release means for releasing the supercooling of supercooled wastewater supercooled by the supercooled water producing heat exchanger to generate an ice particle in the wastewater and recirculated water generation means for separating the ice particle from the wastewater containing the ice particle to obtain clean recirculated water from the separated ice particle is used as the frozen and concentrated wastewater treatment apparatus for recovering the recirculated water.
