METHOD OF IMPROVING THE QUALITY OF WATER USING THE SLUDGE OF A WATER LAND

摘要

A water purification method using sediment of a water land is provided to reuse the dredged sediment by dredging sediment that is an ultimate contamination source of the water land, and to maintain the quality of purified water of the water land continuously. A water purification method using sediment of a water land(10) comprises: a preparation step of draining water in the water land and preparing to form a dredged land(11) and a created land(13); a dredged land and created land forming step of constructing a division part(30) for dividing the dredged land and the created land in the water land, and dredging a sediment of the dredged land to pile the dredged sediment on the created land; and an aquatic plant planting step of planting aquatic plants in the created land formed by the dredged land and created land forming step. The dredged land and created land forming step includes: a sediment dredging step of moving the sediment of the dredged land to the created land; a division part forming step of forming a division part to divide the dredged land and the created land; and an adjusting step of adjusting the dredged land and the sediment piled up on the created land.
