Reparation device for large polluted soil area and reparation method thereof

Abstract

The invention discloses a reparation device for a large polluted soil area and a reparation method thereof. The reparation device comprises a traction trolley bracket. A plurality of wheels which areuniformly arranged are arranged at the bottom end of the traction trolley bracket. A box body is arranged in the traction trolley bracket. The box body is of a cavity structure. The box body is internally provided with a vertical screen plate. A water pump is arranged on one side of the screen plate. The output end of the water pump sequentially penetrates through the wall of the box body and thetraction trolley bracket, and is connected with a flow guide pipe located at the bottom end of the traction trolley bracket. A plurality of spraying nozzles are uniformly arranged at the flow guide pipe in a surrounding mode. An air cylinder is arranged at the bottom end of the traction trolley bracket and on one side of the flow guide pipe. A soil turning mechanism is arranged at the bottom end of the air cylinder. A stirring mechanism is arranged at the top end of the box body. The whole design is simple and reasonable. Soil turning operation is conducted after full dissolution of an elutingagent, and therefore polluted soil reparation is more comprehensive. Through arrangement of the traction trolley bracket, reparation working of the large polluted soil area is achieved, and manpower,material resources and financial resources are greatly saved.

Description

technical field [0001] The invention relates to the field of soil remediation, in particular to a remediation device and a remediation method for large-area polluted soil. Background technique [0002] At present, the treatment methods of heavy metals mainly include biological enrichment method, soil replacement method, spray purification method and so on. Among them, the biological enrichment method decreases slowly, and the purification cycle is too long. The soil replacement method can only dilute the heavy metals in the soil, but cannot really remove the heavy metals, so it is potentially dangerous. Therefore, the commonly used method is spray purification. According to the patent No. 201420614386.0, a spray screening machine for polluted soil is disclosed, which includes a housing, a spray device, a screw conveyor and a recovery tank. The problem is that this method is only suitable for small-area soil purification. For large-area soil pollution, this operation is no...

Problems solved by technology

The problem is that this method is only suitable for small-area soil purification. For large-area soil pollution, this operation is not only time-consuming and labor-intensive, but also has low work efficiency, which is not conducive to soil remediation.
