<p>The present invention relates to an apparatus for washing an inner wall of a filtration tank of a water treatment facility. The purpose of the present invention is to significantly increase filtration efficiency of the filtration tank by washing attachable impurities, generated on the inner wall of the filtration tank, and by preventing a phenomenon that an inner space of the filtration tank, a filtration layer such as a sand layer in the filtration tank, and a filtration layer facility are contaminated by the impurities, generated on the inner wall of the filtration tank. The apparatus for washing an inner wall of a filtration tank of a water treatment facility is installed on the inner wall of the filtration tank of the water treatment facility and selectively washes the surface of the inner wall of the filtration tank. The apparatus for washing an inner wall of a filtration tank of a water treatment facility comprises: a washing pipe which is formed on one side and is connected to a supply pipe perpendicular to the same, receives washing water from the supply pipe, and is extended along a circumference of the inner wall of the filtration tank on a location which is upwardly apart from an inner bottom of the filtration tank at a certain distance, fixated, and installed; spraying nozzles which communicates with a lower end portion of the washing pipe and is installed on the lower end portion of the washing pipe to be inclined toward the inner wall of the filtration tank in a circumferential direction at certain degrees; and fixation angles which fixate the washing pipe on the inner wall of the filtration tank.</p> |
