HEAVY METAL CONTAMINATED SOIL REMEDIATION EXPERIMENTAL DEVICE

摘要

Disclosed is a heavy metal contaminated soil remediation experimental device, comprising a tank body (20) and a tank cover (3), and further comprising a belt-type stirring device (27), which is located in the tank body and comprises four transmission shafts (48) arranged in a trapezoid shape, wherein rotating wheels (15) are mounted on outer sides of the transmission shafts, a conveying belt (46) is arranged on the rotating wheels in a sleeved manner, inner teeth (16) matching the rotating wheels are arranged on an inner side of the conveying belt, and a plurality of stirring teeth (17) are arranged on an outer side of the conveying be a driving device, comprising an electric motor (18) mounted outside the tank body and a power converter (43) located in the tank body; and sampling ports (14, 23, 24), that are provided in a side wall of the tank body, wherein a sampler (54) is mounted on the sampling port. Uniform anaerobic stirring of an experimental sample agent is achieved, and fixed-point positioning accurate anaerobic sampling work can be achieved without opening the experimental device while guaranteeing an anaerobic environment in the experimental device.
