The present invention relates to a wastewater treatment facility using an air lift aeration pipe for efficiently purifying wastewater, and includes an anaerobic tank, an aerobic tank, and a large number of microbial contact materials therein, and condensed the treated water by aeration. In a wastewater treatment facility formed in the order of an aeration tank for forming an active water stream and a disinfection discharge tank for discharging and discharging the treated water passing through the aeration tank, the wastewater treatment facility includes a primary aeration tank to a hot water tank into which the treated water flows from the aeration tank. Between the upper and lower meshes installed in the middle layers of the aeration tanks to discharge the treated water, a microbial contact material layer filled with plastic containers of large and small sizes is formed, and the lower network of each of the first to fourth aeration tanks. It is installed directly above the bottom of the microbial contact material layer, and blows air hard at the beginning and gradually blows out the air. It installs a decrement amplification engine for reducing the amount of desorbing microbial mass in contact with the surface and the inner surface of the container, each of the first to fourth aeration tank is an upright part installed vertically close to one inner wall, The invention is designed by installing an air lift width pipe integrally formed with a horizontal portion extending horizontally toward the other inner wall while being bent at the upper end of the upright portion. |
