In general, in the conventional wastewater treatment method, the inflow stage where most of the wastewater flows in, the aeration and reaction stages in which oxygen is supplied, the precipitation stage in which the treated sludge is settled, and the treated water treated by removing the precipitated sludge Is configured to allow the overall treatment to be carried out, such as a discharge step to discharge.

In addition, a large number of treatment tanks are required to accommodate such treatment steps sequentially, for example, anaerobic tanks, anoxic tanks, aerobic tanks, sedimentation tanks, and the like, and these treatment tanks are structurally complicated. The situation is not properly effective in maintenance or advanced processing.

Moreover, since most of the wastewater or other treated water flowing into the treatment tank is configured to drop in from the upper part, the wastewater frequently causes adverse effects directly inside the treatment tank during the treatment operation, resulting in lower treatment efficiency. In addition, in the case of the discharged water that is treated in the treatment tank and discharged to the outside, a floating inclination mechanism must be installed so that it can be discharged smoothly to the outside, which is inevitably caused to be adopted.

In order to solve this problem, a single or a plurality of treatment tanks are provided and wastewater is introduced into the treatment tank to remove nitrogen and phosphorus contained in the wastewater by repetitive treatment of aerobic and anaerobic conditions.
