An apparatus for purifying greywater using constructed wetland is provided to reduce hydrophile facilities maintaining cost by purifying and supplying greywater and no subsurface water or water service as water resources used when a hydrophile environment is developed and to use low energy in order to produce water resources supplied to the hydrophile environmental facility. An apparatus for purifying greywater using constructed wetland contains the constructed wetland containing a stop part(2) provided with the greywater and filling up thick Zeolite, an influx unit(1) in which chips are filled and an outlet part(3) in which the thick Zeolite is filled successively. An organic compound, nitrogen and phosphorus in the greywater are removed and purified by generating one condition of an aerobic condition and an anaerobic condition at the influx unit, the stop part and the outlet part.
