PURPOSE: Provided is an advanced wastewater treatment system capable of treating wastewater at low cost using a small number of peripheral devices, wherein organic material is directly removed by removing suspended solid using ozone, phosphorous is removed along with the suspended solid, nitrogen is removed by ammonia stripping using ozone, and bacteria is eliminated by ozone sterilization. CONSTITUTION: The system comprises a flotation tank(200), a sterilization tank(300) connected to the flotation tank(200) by a connection unit(220), ozone dissolving units(400) installed in the flotation tank(200) and the sterilization tank(300), respectively for dissolving ozone into water, a power supply for starting the ozone dissolving units(400), an ozone generator(100) for generating ozone, a scum discharge pipe(214) for discharging scum, and a filter(500) installed after the sterilization tank(300) for adsorbing fine suspended solid from the sterilized water.
