Industrial heavy metal contaminated soil remediation device

Abstract

The invention relates to the technical field of soil remediation, in particular to an industrial heavy metal contaminated soil remediation device which comprises a box body, an adjusting mechanism is arranged on the box body and matched with a stirring mechanism, and the stirring mechanism is arranged in the box body. A transmission mechanism connected with the stirring mechanism is arranged in the box body, and a soil turning mechanism connected with the transmission mechanism is arranged below the transmission mechanism; the adjusting mechanism is arranged to adjust the water amount in the water tank, a lime-sulfur mixture and water can be rapidly mixed through the stirring mechanism, then the lime-sulfur mixture and the water are mixed more evenly, soil is scarified through the soil turning mechanism, and the soil turning efficiency is improved. The lime-sulfur mixture water can be fully mixed with the heavy metal polluted soil, pollution contained in the soil is further reduced, the soil is driven to enter the soil turning mechanism through the arranged transmission mechanism, and then the soil turning mechanism can screen the soil.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to an industrial heavy metal contaminated soil remediation device. Background technique [0002] For mercury-contaminated soil, lime-sulfur mixture can be applied, and sulfur is an effective method to reduce the migration of mercury from soil to crops. After the sulfur is applied, the mercury is more firmly fixed in the soil. The application of phosphate fertilizer is also an effective way to reduce the poisonous effect of mercury compounds in the soil because the solubility of mercury orthophosphate is smaller than that of its hydroxide or carbonate. [0003] At present, the internal mixing process of lime-sulfur mixture mixed into land polluted by heavy metals is not very sufficient. The existing implementation method is to first use mechanical equipment to turn over the soil, and then use manual spraying or high-efficiency mechanical equipment to spray. However, this m...

Problems solved by technology

[0003] At present, the internal mixing process of lime-sulfur mixture mixed into land polluted by heavy metals is not very sufficient. The existing implementation method is to first use mechanical equipment to turn over the soil, and then use manual spraying or high-efficiency mechanical equipment to spray. However, this method can only cover the heavy metals on the surface of the loosened soil, and then degrade them naturally. This method has low work efficiency, and the repair effect of the lime-sulfur mixture is not ideal, and the repair process is cumbersome.
