ている。2. Description of the Related Art Surplus soil generated during various constructions, for example, excavation surplus generated during shield construction or construction of continuous underground walls, hydrous residual soil during foundation work, and waste mud dredging work such as bentonite Hydrous residual soil and slime treated residual soil when constructing cast-in-place piles contain a large amount of water, and especially in mixed mud soil such as bentonite and cement,
Since they show high alkalinity, these residual soils are transported to an industrial waste intermediate treatment plant, where they are neutralized.
It has been subjected to granular solidification through the steps of precipitation, concentration, solidification, and drying.

た。More specifically, a coagulant or the like is generally added to an object to be treated to separate the precipitate into supernatant water, and the precipitate is solidified by solar drying. Therefore, there is a problem in that the drying time is 2 to 4 days, and a large treatment plant is required. In addition, there is a problem in that the supernatant water (processed polluted water) needs to be separately disposed. there were.

状であり、経済的な無駄があった。Further, it is very difficult to determine the amount of the solidified material to be added in consideration of the properties of the material to be treated and the water content. However, resuming the processing is a waste of time, so that the current situation is that the solidifying material is often added more than necessary, which is economically wasteful.
