PURPOSE: A water supply and discharge purifying system for a water tank type farm is provided to improve the durability thereof and to reduce the installation costs thereof. CONSTITUTION: A water supply and discharge purifying system for a water tank type farm comprises a filtering device(100), a feed pump(200), an ejector(300), a purifying tank(400), a contaminated water tank(500), a compressed air supply device(600), and a controller. The filtering device is formed in the shape of a sealed tank and is equipped with an intake pipe and a supply pipe. A filter screen filtering foreign materials is formed inside the filtering device. The feed pump pumps water accepted to a culturing tank. The ejector generates negative pressure and applies the pressure to the supply tube or air supply pipe. The purifying tank comprises a third circulating pipe. The contaminated water tank receives contaminated water. The compressed air supply device supplies compressed air to the compressed air supply device. |
