Claims (5)

It has an inlet and an outlet of sewage at the lower part, and separates the sewage from the sewage, and passes the sewage from the sewage tank, and at the same time, the inorganic coagulant alkali agent and the polymer coagulant are injected from the upstream side to the downstream side of the flow path. The waste agglomeration apparatus, an upward flow passage through which wastewater from the waste agglomeration apparatus is introduced, and a downward flow passage thereafter, are connected to the microbubble mixed water introduction pipe at the lower portion of the upward flow passage, and the upward flow passage Filthy waste on top of And a bubble mixed water generator connected to the microbubble mixed water introduction pipe. The sewage tank of claim 1, wherein the separation tank guides the sewage introduced at the lower sewage inlet to flow upward and the sewage at the sewage rising station is changed to its flow direction to flow downward. A water treatment apparatus, comprising: a purified water dropping station and a floating dirt collecting unit having a narrow shaft portion at least partially disposed on the upper surface of the purified water lowering station and the upper station of the two stations. 2. An inorganic coagulant mixer, an alkaline coagulant mixer, and an inorganic coagulant pump and an alkaline coagulant pump connected to the fluid inlet side of each of the mixers according to claim 1, wherein the dust agglomeration apparatus is connected in series from the upstream side to the downstream side of the flow path. (Iii) A water treatment apparatus comprising a pump, a polymer coagulant pump, and an inorganic coagulant tank, an alkaline tank and a polymer coagulant tank connected to the suction side of each of these pumps. According to claim 1, wherein the pressure flotation sedimentation tank has a first passage having a sewage inlet at the bottom, and a sewage outlet at the top, and surrounds the first cylinder with concentric intervals, the lower end of the fluid outlet, and the upper end of the suspended sewage outlet. A second passage which is connected to an upper end of the second passage, and a dirt extraction tube having a shaft diameter portion at least partially connected to an upper end of the second passage, and a bubble mixing confluence introduction tube connected to a lower portion of the first passage. Water treatment device. The gas bubble outlet according to claim 1, wherein the bubble mixing water generator is composed of a gas nozzle and a liquid nozzle inserted around the outer periphery of the gas nozzle, in which liquid flows from the periphery of the gas nozzle to the front of the jet nozzle. The liquid chamber is formed on the outer periphery of the gas nozzle so as to join on the center line of the water treatment apparatus, characterized in that it comprises a wide end tapered hole concentrically with the center line of the gas outlet from the liquid chamber. ※ Note: The disclosure is based on the initial application.
