A method for regenerating a well with sumps is provided to improve the quality of underground water within the well, maintain clean supply and drainage and preserve water environment, by completely removing pollutants causing lowering an efficiency of the well such as slime generated in the well due to long use of the sumps using chemicals, metal materials and microorganism. An inner portion and a wall surface of a well(1) are photographed by a photographing unit. Underground water within the well is drained to the outside through a water pump and a drainage pipe. A connection pipe and a finishing valve are installed within the well. A surface of an inner wall of each horizontal sump is photographed by the camera unit. The photographed inner portion of the well is cleaned by using a vertical clean unit and a horizontal clean unit, thereby removing pollutants from the inner portion of the well. Underground water containing pollutants is drained to the outside through an air sprayer. An induction pipe(60) is installed at the inner portion of the well. Chemicals are inputted into the induction pipe to be chemically reacted in the induction pipe. The reacted chemicals are sprayed to the inner portion of the well and an inner portion of each horizontal sump. Underground water containing the chemicals is drained to the outside through the air sprayer. The inner portion and the wall surface of the well are again photographed by the photographing unit. |
