Technical Field

[0001] The utility model relates to the technical field of corundum wastewater treatment, in particular to a multi-stage sedimentation tank for corundum wastewater treatment. Background Art

[0002] Carborundum, also known as silicon carbide, carbon silicon stone, and refractory sand, is a refractory material made of quartz sand, petroleum coke (or coal coke), and sawdust through high-temperature smelting in a resistance furnace. It is a non-metallic carbide of silicon and carbon elements covalently bonded. Carborundum is very hard, has excellent thermal and electrical conductivity, and can resist oxidation at high temperatures. Carborundum will produce wastewater during its processing and production. The wastewater contains small solid particles, which requires precipitation treatment operations. During the use of the existing sedimentation tank for carborundum wastewater treatment, the sedimentation channel and the filtration structure are relatively simple, resulting in the incomplete precipitation of the carborundum wastewater, which affects the sedimentation treatment effect of the carborundum wastewater.
