Abstract:
1. A water treatment apparatus comprising: a first treatment tank which receives water to be treated, and includes a first support, forming thereon a first, fixed bed comprising a powdery phosphorus adsorbent comprising an inorganic layered compound, wherein the first bed separates phosphorus and solid matter from the water, and recovers the phosphorus in a state adsorbed on the phosphorus adsorbent in the first bed, which is usable as it is; a second treatment tank which receives the water treated in the first treatment tank and a powdery phosphorus adsorbent comprising an inorganic layered compound, and includes a second support, forming a second, fluidized or fixed bed comprising the phosphorus adsorbent, wherein the second bed separates phosphorus from the water received from the first treatment tank, and recovers the phosphorus in a state adsorbed on the phosphorus adsorbent in the second bed, which is usable as it is; and a transferring device configured to transfer the phosphorus adsorbent, having phosphorus adsorbed thereon in the second treatment tank, from the second treatment tank to the first treatment tank.
