Gangue is a waste product in the process of coal mining and processing. Its unreasonable stacking not only occupies a large amount of land resources, but also releases heavy metals through natural processes such as rainwater washing and weathering, thereby polluting the surrounding soil. These heavy metals accumulate in the soil, which will destroy the soil structure, reduce soil fertility, affect the growth of crops, and even enter the human body through the food chain, posing a potential threat to health.
How to treat the heavy metal pollution in the soil caused by gangue stacking? Chemical washing remediation technology can be used to use chemical reagents to leach heavy metals from the soil. Reagents should be carefully selected to avoid secondary pollution. Desen washing remediation equipment is based on physical and chemical principles. By fully contacting gangue with specific eluents, heavy metals are dissociated from gangue and dissolved in the eluent.
DS gangue water washing equipment has the following characteristics:
High efficiency: It can process a large amount of gangue in a short time and improve work efficiency.
Accuracy: The washing parameters can be adjusted for different types and degrees of pollution of gangue to ensure the remediation effect.
High degree of automation: reduce manual operation, labor intensity and human error.
Pre-treatment of coal gangue such as crushing and screening can improve the subsequent washing effect. Control the concentration, temperature, flow rate and other parameters of the washing agent to ensure the full dissociation of heavy metals. Separate the leached coal gangue and the washing liquid containing heavy metals, and recycle the heavy metals in the washing liquid. Desen washing and remediation equipment can significantly reduce the heavy metal content in coal gangue and reduce the risk of soil pollution. The equipment operates stably and the maintenance cost is relatively low.
The problem of heavy metal pollution in the soil caused by the stacking of coal gangue needs to be solved urgently. The comprehensive use of various treatment methods and the combination of advanced Desen soil washing and remediation equipment are expected to achieve effective treatment and ecological environment restoration. However, in actual application, it is necessary to fully consider factors such as cost and environmental impact and formulate a scientific and reasonable treatment plan. At the same time, strengthening the source management and standardized stacking of coal gangue to prevent the occurrence of soil pollution is an important guarantee for achieving sustainable development.
