SEWAGE AND WASTEWATER TREATMENT SYSTEM

The present invention relates to a wastewater treatment system. The wastewater treatment system according to the present invention purifies wastewater through a physicochemical reaction process forming floc by inputting a coagulant into the wastewater and an emission process floating the floc to the top of a floating facility and emitting the same. The present invention comprises: a pipeline-type reactor forming the floc by combining a tubular flow reaction and a physiochemical mixed reaction; a high-speed screw-type rapid agitator installed in the pipeline-type reactor and forming microbubbles which can improve a floating effect of the floc; and a rapid floating tank capable of changing a channel according to the concentration of pollutant forming the floc. Thus, the present invention maintains economic feasibility desired in the wastewater treatment system, shortens a physiochemical reaction time of the wastewater, and provides the wastewater treatment system which may reduce facility costs, maintenance expenses, and process time.
