PURPOSE: Water purification equipment of sewage and wastewater is provided to improve a removal efficiency of sludge by allowing the sludge to rapidly float on the surface of water to be removed. CONSTITUTION: Water purification equipment includes a stirring unit (100), a body unit (200), a bubble water supplying unit, a spraying unit (400), and a sludge removing unit (500). The stirring unit stirs a sewage and wastewater with a chemical to be coagulated. The bubble water supplying unit supplies bubble water (50) to the sewage and wastewater which passes through a transferring pipe (390). The transferring pipe connects the stirring unit and the body unit. The spraying unit, which is in connection with the transferring pipe, is arranged under the surface of raw water (10) in the body unit and sprays mixed water (70), in which the bubble water and the sewage and wastewater are mixed, into the body unit. The sludge removal unit is arranged on the surface of the raw water in the body unit and removes floating sludge from the mixed water. |
