PROBLEM TO BE SOLVED: To provide a construction method for treating sludge, which eliminates difficulty in finding a place for disposing of the polluted sludge, even if the polluted sludge is dredged, which prevents the occurrence of hydrogen sulfide, which can improve water quality by reducing phosphorus, nitrogen, etc., and which enables the cut-off of a food chain from the bottom of water, polluted with a harmful substance. SOLUTION: A gently sloping revetment is formed by laying transparent bags, filled with the polluted sludge, all over a prescribed place; next, slag from steelmaking and/or granulated blast furnace slag and/is laid and levelled off on the gently sloping revetment; the sludge is consolidated for settlement; the quality of ambient water is improved with filtration of drainage from the sludge; and after that, the sludge is covered with sandy soil according to need, so that a submarine forest can be created.
