PURPOSE: A method for improving quality of water is provided to prevent environmental contamination while preventing vibration and noise due to dehydration operation, and to reduce the time and the costs by suspension of work. CONSTITUTION: A method for improving quality of water includes the following steps of: moving a transfer pipe to the surface of an operation place or mounting a transfer pipe to a dredging robot;(S10); settling sludge on the bottom by dropping the dredging robot or a dredging machine to underwater(S20); transferring the sludge to the outside by rotating a screw or a brush(S30); injecting the transferred sludge into a dehydration pipe having membrane structure(S40); recycling filtered water from the outside(S50); and recycling and drying the sludge remaining inside the dehydration tube(S60). |
