Description

Technical Field

[0001] The utility model relates to the technical field of copper electrolysis production in smelters, in particular to a wastewater treatment system for washing concentrate transport vehicles. Background Art

[0002] After unloading copper concentrate, a small amount of concentrate remains inside the vehicle's compartment due to the water content of the concentrate. Furthermore, as the vehicles travel through the concentrate storage depot, copper concentrate is stuck to the wheels. If the vehicles are not washed and then driven onto the road after leaving the depot, the copper concentrate can spill onto the ground, causing metal loss, dust, and soil and water pollution, significantly impacting the environment. Therefore, the transport vehicles need to be cleaned. The current traditional car wash method involves using a hose to connect water to a source to rinse the vehicle compartment and wheels. The wastewater from the wash flows through a ditch to a sedimentation tank for sedimentation, where it is pumped to a car wash for washing. This car wash method has several issues: 1. The sedimentation tank requires frequent cleaning. Since each vehicle carries approximately 100 kg of copper concentrate after unloading, a large amount of copper concentrate is deposited in the sedimentation tank, requiring frequent cleaning of the primary sedimentation tank. Since there are no vehicles in the primary sedimentation tank area, excavators are required for cleaning. 2. The car wash is inefficient and time-consuming. Because a single water pipe is used for washing, car wash efficiency is low, washing time is long, and vehicle waiting times are long, which puts a certain pressure on traffic within the factory. 3. The car wash wastewater quality is poor, causing serious corrosion to vehicles and pipes. Because the car wash wastewater only undergoes sedimentation without further treatment, the water has high heavy metal content and is acidic, causing serious corrosion to vehicles, equipment and pipes.
