REUTILYZING METHOD OF RIVER DREDGED SOIL AND SOIL IMPROVEMENT PLANT FOR THE SAME

摘要

PURPOSE: A method for recycling contaminated dredged soil and a soil improving plate are provided to produce various recycled products of stable quality by combining mechanized construction with the improvement of soil. CONSTITUTION: A method for recycling contaminated dredged soil is divided into a pre-treating process(S10) and a post-treating process(S20). Dredged soil is collected, and sludge is extracted(S11, S12). A coagulating agent is introduced to extract silty sludge(S13). The silty sludge is dehydrated(S14). The sludge is introduced into a plate(S21). Improved soil is obtained by mixing the sludge and a soil improving agent(S22). The soil improving agent is automatically injected to the sludge according to a pre-set program. The improved soil is shaped and dried(S23).
