Abstract
The invention discloses a movable ultrasonic stirring cleaning tank and method for repairing heavy metal contaminated soil. Multiple cavities separated by partition plates are sequentially arranged in a tank body in the axial direction. A stirring shaft penetrates the partition plates in sequence. A set of stirring blades are distributed in each cavity. A communicating hole is formed in each partition plate. The forming positions of the communicating holes and the positions of the communicating holes in the adjacent partition plates are distributed in a staggered manner. Baffling is formed when materials pass through the cavities in sequence. After the contaminated soil and a cleaning agent are mixed according to a certain proportion, the mixture is continuously fed into the tank body at a certain flow speed through a feeding port, cleaning is conducted for 30 min to 60 min under the ultrasound-stirring double effect, and therefore elution of heavy metal can be completed. The movable ultrasonic stirring cleaning tank is compact in structure, convenient to transfer, uniform in stirring, capable of working continuously and high in stirring efficiency.
