Tailings dry discharge

The first stage is sludge concentration to preliminarily reduce the volume of sludge; The second stage is sludge digestion to decompose the organic matter in the sludge; The third stage is sludge dewatering to further reduce the volume of sludge; The fourth stage is sludge disposal to treat the final sludge by some means. The above typical sludge treatment process can achieve the reduction, stabilization, harmlessness and recycling of sludge after treatment. (1) Reduction: Because the sludge has high water content with large volume and fluidity. After the above process, the sludge volume is reduced to one-tenth of its original volume, and its state is converted from liquid into solid, which is convenient for transportation and consumption. (2) Stabilization: The content of organic matter i
