PROBLEM TO BE SOLVED: To provide a compact water treatment apparatus without deteriorating the quality of water.

SOLUTION: The water treatment apparatus is provided with: a first solid-liquid separation tank for performing solid-liquid separation; an aerobic treatment tank for aerobically treating the liquid portion separated in the first solid-liquid separation tank; a second solid-liquid separation tank for further performing solid-liquid separation on the water treated in the aerobic treatment tank; and an aerobic digestion tank. The aerobic digestion tank is made to have a communicative part communicated with the first solid-liquid separation tank and an air diffuser for aerobically digesting the solid portion or sludge separated in the first solid-liquid separation tank is arranged in a position equal to or lower than the highest position of the communicative part.
