Description

Technical Field

[0001] This application relates to the field of wastewater treatment technology, and in particular to a device for treating pharmaceutical workshop testing wastewater. Background Technology

[0002] Biological contact oxidation is a highly efficient water treatment process that uses a biofilm attached to a carrier (commonly known as a packing material) to purify organic wastewater. It has been widely used in the treatment of industrial, pharmaceutical, and domestic sewage.

[0003] Currently, when using biological contact oxidation to treat pharmaceutical workshop wastewater, biological packing materials (biological carriers) are typically used. These materials consist of a central rope and elastic filaments arranged on the outer surface of the rope, forming a mesh structure that is fixed at equal intervals within the treatment tank. During the start-up phase of wastewater treatment, larger spacing is often required to facilitate rapid biofilm formation, while the spacing needs to be appropriately shortened during the stable phase to improve space utilization and treatment efficiency. However, the spacing of existing biological packing materials is not adjustable, making it difficult to meet the spacing requirements at different stages of wastewater treatment. Summary of the Invention
