<p>PROBLEM TO BE SOLVED: To provide a treatment method of dredged mud and sand which is capable of not only perfectly separating the dredged mud and sand into liquid and solid but also surely removing an environmentally contaminated material, or the like contained in the separated muddy water as a contaminated matter, and which can effectively prevent the environment from re-contamination thereby. SOLUTION: This method consists of a process in which the dredged mud and sand are filtered and separated to a liquid matter and a solid matter, a process in which the separated muddy water is added with a necessary condensation agent so that a muddy matter becomes flocked and a process in which the muddy matter flocked by blowing pressurized air thereto is pressurized and floated for removal treatment.</p> |
