ABSTRACT:
An apparatus for wastewater treatment is provided which can efficiently treat wastewater containing organic matter and, in addition, fluorine, with a relatively small number of tanks required for such treatment. The apparatus includes a first tank adapted to allow wastewater to flow thereinto, the first tank comprising an upper portion having a calcium carbonate mineral mass of smaller granule size and an aeration tube for fluidizing such calcium carbonate mineral mass while aerating the same in the wastewater, an intermediate portion and a lower portion which respectively include a calcium carbonate mineral mass of medium granule size and a calcium carbonate mineral mass of larger granule size, the medium and larger granule size masses of calcium carbonate mineral constituting immobilizing carriers for microbial propagation, and a circulation pump for transferring treated water resulting from treatment in the upper portion to the lower portion. In the upper portion, calcium carbonate mineral is fluidized by aeration so as to treat the wastewater through chemical reaction and, in the intermediate portion and lower portion, organic matter in the wastewater is biologically treated by microorganisms.
