Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to an industrial wastewater sedimentation treatment device. Background Art

[0002] Industrial wastewater sedimentation treatment is a physical process used to remove suspended solids and particulate matter from wastewater. This method usually uses the principle that particulate matter in wastewater naturally settles due to gravity in a static state. The design and configuration of industrial wastewater sedimentation treatment equipment needs to be comprehensively considered based on factors such as wastewater quality, treatment volume, discharge standards, and economic costs. Different industrial wastewaters may require different treatment technologies and equipment. Therefore, detailed technical evaluation and engineering design are usually required when selecting and designing sedimentation treatment equipment;
