A water treatment apparatus includes a plurality of meshed tubes made of synthetic yarn and provided with cilia; a plurality of tube stack cages containing the meshed tubes; and an aeration diffuser positioned between the tube stack cages and configured to provide air so that to-be-treated influent water moves to the tube stack cages. The hollow interior of the filter media, i.e. meshed tubes, enables water to move in any direction, and the high porosity maximizes the area for filtering of suspended solids and attachment of microorganisms. The resulting efficiency of removal of suspended solids and soluble organic material is far greater than conventional methods. Arrangement of diffusers in the middle of the reaction tank and between the tube stack cages and aeration by them result in perfect mixing in the reaction tank. The load of suspended solids and soluble organic materials is evenly distributed over the entire filer media.

A biological removal method of phosphorus and nitrogen includes supplying a mixture gas into a gas holder. Inflow water and return water are supplied into the gas holder to make the mixture gas dissolved in the inflow water and the return water. The return water was provided from a granulation biological reaction tank. The inflow water and the return water including the dissolved mixture gas are transported to the granulation biological reaction tank. A nitrogen-based component is removed from the inflow water and the return water using methan-oxidizing bacteria granulated in the granulation biological reaction tank. Treated water without the nitrogen-based component is transported to an anoxic tank for treatment, and discharged from the anoxic tank.
