Embodiment Construction

[0026] The tank used for the method of the present invention is equipped with an electroosmotic device, and some auxiliary electroosmotic dehydration devices can be added to the tank as needed, such as vacuum drainage device, vacuum preloading device, static load device, dynamic compaction equipment and other auxiliary devices , The main function of the vacuum precompression device and static load device is to maintain the sludge capillary structure to improve the efficiency of electroosmosis dehydration. The power supply of the electroosmosis device can be a regulated DC power supply or a pulsed DC electroosmosis power supply.

[0027] The electroosmosis device uses composite pipes or other electrical conductors such as diversion electrode rods as cathode and anode electrodes. The composite pipe is a composite electrode drainage pipe integrating drainage, negative pressure transmission and electrodes. There are many small holes in the cloth, and the percolation membrane is wrappe...

Abstract

The invention relates to a tank type electro-osmosis method for reconstructing soil with silt; the method adopts a tank as a silt treatment carrier for electro-osmosis dewatering, and then a vacuum drainage device or / and a vacuum preloading device or / and a static load device or / and a forced ramming device can be additionally arranged according to requirements for improving dewatering efficiency; the assignment of the electrodes of an electro-osmosis device can be in a horizontal way or a vertical way, which is flexible and diversified; the method of the invention has large treatment capacity and can simplify equipment and lower cost to the utmost extent, and high voltage and strong electric current can be applied during electro-osmosis to shorten treatment time and enhance dewatering efficiency.

Description

Technical field [0001] The invention relates to a silt rebuilding method, in particular to a method for electroosmotic silt rebuilding using a tank as a processing carrier and a device used for implementing the method. Background technique [0002] At present, in the technical field of sludge dewatering and reclaimed soil treatment, there is no report about using trough as a carrier for electroosmotic dehydration and reclaimed soil. The applicant in this case proposed a technical solution for pulse electro-osmosis dewatering treatment of soft soil and silt using troughs as a carrier, and applied for a patent to the Patent Office of the State Intellectual Property Office of China. The patent application number is 200810073429.8 and the name of the invention is , Sludge pulse electro-osmosis dehydration treatment force method and its device". This method is simple to operate. It uses the core principle of electroosmosis to dehydrate soft soil and silt, and produces a good treatment...
