How to reduce the environmental pollution caused by coal washing?

May.08,2024

1. Water pollution: The cleaning water and wastewater used in the coal washing process will contain a large amount of coal ash, coal dust, cinder and other solid particles and organic matter. If it is directly discharged without treatment, it will seriously pollute groundwater, rivers and other water bodies.

2. Air pollution: The coal dust and dust produced during coal washing will be scattered with the airflow, which will not only affect the health of workers, but also affect the quality of life of surrounding residents.

3. Land destruction: The layout of coal washing plant equipment and the waste residue and waste soil generated during the coal washing process will occupy a large amount of land resources, and will also cause land damage and ecological disasters.

In order to mitigate the negative impact of coal washing on the environment, we can start from the following aspects:

1. The wastewater during the coal washing process must be treated by the coal slime water treatment system. The dehydrated coal slime enters the tail coal bunker, and the clean water is used as circulating water. The coal washing plant has a closed-circuit cycle of washing water. Even if a part of the water is discharged, it must meet the discharge standards. The design process will not pollute the water quality.

2. Scientific and rational utilization of coal washing waste residue: Through scientific treatment methods, coal washing waste residue can be turned into treasure to reduce the accumulation of waste residue and damage to the land.

3. Introduce new technologies: Introduce new high-efficiency, low-energy-consuming technologies, such as high-efficiency, low-energy-consuming screening and sorting technologies, to reduce the impact of coal washing on the environment.
