Title:
発生土処理方法及び装置
Document Type and Number:
Japanese Patent JP3626877
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve neutralizing processing efficiency and safety by gelatinizing produced earth by agitating/mixing these by adding a water absorbing agent and a solidifying agent to the generating earth, generating a granular body by forming a particle by dividing an inside substance of the gelatinized generating earth, and forming a coating film by performing neutralizing processing on a surface after leaving the generated granular body as it is for a prescribed period. SOLUTION: In a primary processing system 11, a gravel component B is removed from generating earth A. In a secondary processing system 21, dewatering processing is performed by adding a coagulant D to generating earth C processed in the primary processing system 21 to generate a dewatered cake E. In a tertiary processing system 31, a water absorbing agent (water glass) G and a solidifying agent (cement) H are added to the dewatered cake E to be agitated and mixed to be formed into a particle while dividing an inside substance to generate a granular body F. In a quaternary processing system 41, after leaving the granular body F as it is for a prescribed period, neutralizing processing is performed on a surface to form a coating film. Thus, neutralizing processing efficiency and safety can be improved by properly performing the neutralizing processing.
