A simulation experiment device for the release of heavy metals in tailings sand

Abstract

The invention discloses a simulation experiment device for releasing heavy metals in tailings sand. By setting up a plurality of simulation experiment boxes, the invention can well realize the comparison operation of data, and at the same time, air-dry and shower each simulation experiment box at the same time. Operation, in this way, can truly simulate the reality of rainy, dry and other conditions, realize the all-round simulation of tailings sand, improve the accuracy of data experiments, ensure the authenticity of simulation experiments, and facilitate the analysis and comparison of the release of heavy metals. In order to provide a reference basis for the treatment of heavy metals; the present invention is provided with a leaching device, and by controlling the second electric valve, the pH adjustment of the rinsing water can be realized, thereby realizing the simulation of acid rain rinsing of tailings, and the box is equipped with The heater and refrigerator can realize the temperature adjustment during the leaching process, so as to realize the simulation of tailings rainwater leaching at different temperatures.

Description

technical field [0001] The invention relates to the technical field of heavy metal detection equipment, in particular to a heavy metal release simulation experiment device in tailings sand. Background technique [0002] For tailings sand, a large amount of tailings is usually stored in the open air, which not only occupies land resources, but also undergoes weathering, rainwater leaching, especially acid rain leaching, which leads to the migration of various harmful components and affects soil, groundwater and surface water. Pollution and environmental risks. [0003] At present, most of the experimental devices used to simulate the release of heavy metals in tailings have single functions, and generally only rely on simulating the leaching process of rainwater, which not only lacks data comparison, but also makes it difficult to truly simulate the release environment and conditions of heavy metals in reality, resulting in There are errors in the experimental data.
