Embodiment Construction

[0030] The technical solution of the present invention will be described in detail below in combination with the embodiments and the accompanying drawings.

[0031] Such as figure 1 and figure 2 shown,

[0032]A leaching test device for testing the release and migration of heavy metal elements, comprising: a bracket 13, a leaching column (7), a first leaching collection bottle 11 with scales, a second leaching collection bottle 27, a vacuum pump 12, and a safety bottle 26. The leaching column 7 is placed on the support 13, the second leaching collection bottle 27 with scale is placed at the lower end of the leaching column 7, and a suction leakage meter 9 is arranged on the side of the leaching column 7. The height of the leaching column 7 is greater than or equal to 105 cm, the inner diameter of the leaching column 7 is greater than or equal to 12.5 cm, and the absorption leakage instrument 9 is connected to the first leaching collection bottle 11 through the first cathete...

Abstract

The invention belongs to the field of environmental geotechnical and environmental engineering, in particular relates to a leaching test device and method for indoor heavy metal pollutants and provides a leaching test device for testing release and migration of heavy metal elements. The test device can be used for monitoring physical conditions of various layered rock and soil mass and release and migration of the heavy metal to underground water, and sampling and detecting each layered rock and soil mass and leaching liquid in real time; the test device is capable of simulating the processes of leaching, migrating and converting of the heavy metal elements in each layer of the rock and soil mass. The invention also provides a leaching test method for testing release and migration of heavy metal elements. The method comprises the following steps: filling a leaching column, and arranging a pressure gage, a suction leakage meter, a flow meter and sampling time intervals to test and obtain solid samples different in flow in different time periods and different layers and the concentration of the heavy metal elements in a leaching liquid sample. The method is capable of effectively simulating the concentration parameters of the heavy metal elements in different leaching column layers under the action of leaching.

Description

technical field [0001] The invention belongs to the field of environmental geotechnical and environmental engineering, and in particular relates to a leaching test device and method for heavy metal pollutants. Background technique [0002] Rock and soil bodies containing heavy metal elements are widely distributed in my country, especially black rock formations that contain metal elements to form metal ore bodies, but acid mine water is easily formed in the tailings formed after mining or during the weathering of rock mass, resulting in water-rock chemistry. A large amount of toxic and harmful heavy metal elements are released, and gradually spread into the water environment to pollute the surrounding soil environment. The pH value of acidic water is usually low, and can be as low as 2 to 3 in severe cases, which is easy to corrode and acidify rock and soil, and accelerate the release of heavy metal elements such as lead, arsenic, cadmium, copper, etc. from rock and soil. In...
