Description

Technical Field

[0001] This utility model belongs to the field of industrial wastewater treatment technology, and specifically relates to a pre-recovery device for industrial wastewater treatment. Background Technology

[0002] Industrial wastewater treatment refers to the removal of pollutants from industrial wastewater through a combination of processes to ensure compliance with discharge standards. It typically consists of four stages: pretreatment, physicochemical treatment, biological treatment, and advanced treatment. Each stage employs appropriate technologies for different types of pollutants, such as screening, sedimentation, flotation, adsorption, filtration, activated sludge process, and reverse osmosis. The treatment processes must be rationally selected and combined based on the wastewater's properties, composition, and discharge standards. After treatment, sediment recovery devices are usually used to collect sediment generated during the treatment process for secondary treatment.

[0003] In industrial wastewater treatment, wastewater containing oil, acids, alkalis, or heavy metals needs to be purified through processes such as chemical precipitation, electrolysis, and filtration. Existing technologies suffer from low treatment efficiency, easy clogging of recovery devices, and incomplete acid and alkali recovery. Furthermore, traditional devices struggle to achieve multi-stage synergistic treatment. For example, the efficiency of oil removal from oily wastewater is insufficient, easily causing secondary pollution; in acid and alkali wastewater treatment, traditional methods cannot effectively recover acids and alkalis, leading to increased subsequent treatment costs. Therefore, we propose a pre-recovery device for industrial wastewater treatment. Utility Model Content
