A wastewater treatment system is provided to recycle the wastewater and effectively use heat generated in the treatment process of the wastewater by properly treating wastewater. A wastewater treatment system comprises a wastewater tank(1), a carbonization apparatus(2), a hot water tank(3), a heat exchanger(4), a reverse osmosis membrane type filtration apparatus(6), an ozone purification apparatus(7), and a regenerated water storage tank(8). The wastewater tank stores wastewater to be treated. The carbonization apparatus heats wastewater supplied from the wastewater tank and carbonizes foreign materials contained in the wastewater. The hot water tank stores hot water. The heat exchanger performs heat exchange between hot water and vapor generated from the carbonization apparatus. The heat exchanger heats the hot water while cooling the vapor. The reverse osmosis membrane type filtration apparatus filters liquid cooled by the heat exchanger. The ozone purification apparatus purifies the liquid filtered by the reverse osmosis membrane type filtration apparatus. The regenerated water storage tank stores regenerated water purified by the ozone purification apparatus. |
