Abstract

This utility model relates to the field of wastewater treatment technology, specifically a sedimentation device for wastewater treatment, including a wastewater tank. A collection box with an open top is slidably connected inside the wastewater tank, and a filter screen is slidably connected inside the collection box. The filter screen of this utility model filters large particulate impurities in the wastewater. An arc-shaped guide plate provides a slow water injection effect. The water purification agent is discharged into the wastewater tank through a guide hood and an L-shaped pipe. The motor is started to drive the stirring rod to agitate the wastewater. A drainage pump discharges the treated wastewater, and a sewage pump discharges the sediment. This slow water injection effect avoids the original sediment and clear liquid becoming cloudy again when adding the waste liquid to be treated, increasing work efficiency. It can filter and collect large particulate impurities in the wastewater, preventing clogging of the sewage pump. Excess sediment can be sucked to the outside. The triangular plate further improves the convenience of cleaning the sediment.
