(57) [Summary] [Purpose] Providing a method for treating sediments such as lake water [Structure] A method for treating sediments deposited at the bottom of the freshwater sphere, including lakes, rivers, waterways or reservoirs. A method for treating sediments such as lakes and marshes, which comprises selectively collecting mud which forms a surface layer of the sediments, dehydrating it to reduce the content of alkali metals, and then drying it to obtain a ceramic raw material. [Effect] Muddy soil can be effectively used as a raw material for ceramics such as cement, and it is easy to implement because it can be used as a part of conventional cement raw material only by selectively collecting sediment soil and performing dehydration treatment. Is far less. In addition, since organic substances are burnt and removed during heating and drying, a bad odor is removed and handling is easy. |
