Abstract:
PROBLEM TO BE SOLVED: To provide a method of removing organic matter in a removed submarine sludge containing an organotin compound, which is carried out at the same time when the high-water-content dredged soil containing the organotin compound is separated into surplus water and earth and sand and the organotin compound is removed from each of the separated surplus water and the separated earth and sand. SOLUTION: This method includes a step to convey the high-water-content dredged soil containing the organotin compound to a flocculating/settling basin 5, a step to add a flocculant to the basin 5, agitate the dredged soil with the added flocculant and separate the dredged soil into earth and sand, flock-settled sediments and seawater, a filtration step to supply the separated seawater and floating flocks to a sand filtration tank and an activated carbon adsorption tank 9 and remove the suspended matter and the organotin compound contained in the separated seawater, a step to withdraw the earth and sand and the flock-settled sediments from the basin 5 and dry them, and further, a step to stick the organotin compound in the floating flocks of a fixed amount of the organotin compound contained in the dredged soil to a polyethylene sheet 7, which is carried out before the filtration step.

Abstract:
PROBLEM TO BE SOLVED: To provide a method of producing salt capable of making salt production work more efficient because calcium sulfate generated in a salt production process hardly adhere to a treating vessel and is easily precipitated and removed. SOLUTION: The method of producing salt comprises an concentrating process of forming a highly concentrated sea water having a salt concentration of 18-22 mass% from sea water, a primary concentrating process of forming a highly concentrated salt water 30 by decreasing a water content in the highly concentrated sea water, a settling process precipitating calcium sulfate 40 by leaving the highly concentrated salt water 30 at rest, a purification process removing the precipitated calcium sulfate 40 from the highly concentrated salt water 30, and a secondary concentrating process of forming saturated salt water by decreasing a water content in the highly concentrated salt water 30 from which the calcium sulfate 40 is removed. Since the calcium sulfate 40 separated out in heating to concentrate the highly concentrated sea water of a salt concentration of 18-22 mass% hardly adhere to the inner surface of the treating vessel 11 and the like so that calcium sulfate removing work becomes unnecessary, which results in making the salt production work efficient.
