Description

Technical Field

[0001] The utility model belongs to the technical field of treatment of leachate from phosphogypsum slag field, and particularly relates to a leachate purification device from phosphogypsum slag field. Background Art

[0002] Phosphogypsum refers to the solid waste residue produced when phosphate ore is treated with sulfuric acid during the phosphoric acid production process. Its main component is calcium sulfate dihydrate, which is usually powdery and generally has an appearance of grayish white, grayish yellow, light green, etc. The annual discharge of phosphogypsum in my country is huge, about 20 million tons, and the cumulative discharge is nearly 100 million tons. It is the largest type of gypsum waste residue. Its random discharge and accumulation will seriously damage the ecological environment, not only polluting groundwater resources, but also causing waste of land resources. Among them, the phosphogypsum slag field leachate purification device is mainly used to treat the leachate containing high concentrations of phosphorus, nitrogen, heavy metals and other harmful substances generated by the phosphogypsum slag field. Through a series of physical, chemical and biological treatment processes, the harmful substances in the leachate are removed or reduced to meet environmental protection standards, and the leachate is purified.

[0003] However, when the leachate purification device currently on the market cleans the inner wall of the purification device, a rotating column generally drives a cleaning scraper or a cleaning head to clean the inner wall of the purification device. However, when the cleaning scraper or the cleaning head cleans the inner wall of the purification device, it may be damaged due to mechanical vibration or external force impact. Moreover, when the cleaning scraper or the cleaning head contacts the inner wall of the purification device, the cleaning effect may be poor due to uneven or excessive force, and the inner wall may even be damaged.
