PROBLEM TO BE SOLVED: To provide a water treatment device capable of showing a prescribed sludge storing capacity by suppressing clogging of a suction port of a transfer pump or a transfer conduit by a large solid matter such as a toilet paper, and by suppressing transfer of a solid matter into a sludge storing tank.SOLUTION: A water treatment device has a solid/liquid separation tank for separating a solid matter from water to be treated containing sludge, and a bisected sludge storing tank for storing sludge separated in the solid/liquid separation tank. In the water treatment device, a first sludge storing tank is communicated with a bottom part of the solid/liquid separation tank, the first sludge storing tank is connected to a second sludge storing tank through a connection port, the connection port is arranged under a communication opening between the first sludge storing tank and the solid/liquid separation tank, and an air diffuser and a transfer pump for transferring in-tank liquid in the second sludge storing tank to the first sludge storing tank are arranged respectively in the first sludge storing tank and the second sludge storing tank. |
