[0002] The oilfield mining wastewater sedimentation tank is a key facility for treating wastewater generated during oilfield mining. Its main function is to remove solid suspended matter that can be precipitated in the wastewater through gravity sedimentation, especially suspended particles with a density greater than that of water. After the sewage enters the sedimentation tank, the suspended impurity particles in the water flow settle downward at a speed greater than the flow rate of the water flow, or the downward sedimentation time is less than the time it takes for the water to flow out of the sedimentation tank. These impurity particles can be separated from the water, thereby achieving water purification.
