This invention relates to the field of wastewater treatment technology, and more particularly to an urban domestic wastewater treatment device including a treatment pump station. The top of the outer arc surface of the treatment pump station is provided with a flange inlet, and the bottom of the inner arc surface of the treatment pump station near the flange inlet is connected to a conical flow guide plate. The upper surface of the conical flow guide plate is provided with an inlet in the middle. The conical flow guide plate is a double-layered structure with an arched end inside. Through a special structural design, the water flow is guided to form a slow flow state, providing sufficient reaction time for the coalescence of tiny oil droplets. This promotes the fusion of emulsified oil droplets and dispersed oil droplets to form large oil droplets. Utilizing the physical property that the density of oil is less than that of water, the oil droplets can naturally float to the surface and form a stable floating oil layer. The entire oil-water separation process does not require additional power and can be completed solely by gravity, effectively improving the oil-water separation efficiency while reducing the energy consumption and maintenance costs of the device.
