PURPOSE: A wastewater treatment device is provided to minimize facility size and to react wastewater and water processing chemicals with low electrical energy consumption by processing the wastewater in a plurality of sedimentation tanks and settling tanks. CONSTITUTION: A wastewater treatment device includes a plurality of sedimentation tanks(100,110,120,130) in which sludge in wastewater is precipitated, used as connection pipes. A coagulating agent is supplied to coagulate the sludge in wastewater. A settling tank(300) is installed on one side of the sedimentation tank among the plural sedimentation tanks. A non-power mixer(400) is installed to precipitate floc on the sedimentation tank. |
