The present invention provides a first anoxic tank for denitrifying nitrate nitrogen in wastewater, an aerobic tank connected to the first anoxic tank for oxidation and nitrification of organic matter, and a further denitrification process for nitrate nitrogen connected to the aerobic tank. A membrane separation tank which is connected to a second anoxic tank, the second anoxic tank to oxidize residual organic matter, nitrification occurs, and solid-liquid separation of treated water and microorganisms, and is installed in the membrane separation tank, and separates treated water and sludge. And a first conveying line for returning the activated sludge in the aerobic tank to the first anoxic tank, and further passing the waste water passed through the first anoxic tank and the aerobic tank to the second anoxic tank and the membrane separation tank. By continuously providing anaerobic-aerobic conditions to the microorganisms in the wastewater, the nitrogen, phosphorus and organics in the wastewater are repeated. Removed, cucumbers, relates to a wastewater treatment apparatus and a high processing using the same method, characterized in that to increase the waste water treatment efficiency. |
