This utility model provides an oilfield wastewater and sludge treatment device, relating to the field of oilfield wastewater and sludge treatment technology. The treatment tank has a drive shaft and a driven shaft rotatably connected to its side. In this utility model, a filter timing belt, a first torque motor, rollers, and a guide plate are installed. The filter timing belt, driven by the rollers, carries the filtered sludge to the guide plate, solving the problem of blockage caused by pouring large amounts of oily sludge into the treatment tank. The separated sludge is squeezed through a screw rod, a pipe groove, a second torque motor, a bottom plate, a water filter tank, and a sludge discharge port, squeezing out the wastewater and oil contained within the sludge, thoroughly separating the oil and sludge. Wastewater from the wastewater collection tank is then discharged into the treatment tank for further treatment via a water pump, suction pipe, and drainage pipe, ensuring full utilization. A sludge scraper is installed to scrape off the sludge adhering to the filter conveyor belt, preventing it from falling into the treatment tank.
