Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment packing technology, specifically a self-sinking biological adsorption ball wastewater treatment packing. Background Technology

[0002] Self-sinking bio-adsorption balls are a type of biological carrier used in wastewater treatment. Their core function is to improve wastewater treatment efficiency by providing an environment for microbial attachment and growth. These fillers are typically made of polypropylene (PP), polyurethane, volcanic rock, and other materials to form a spherical structure. They are porous, lightweight, corrosion-resistant, and easy to clean, making them suitable for functions such as biofilm formation, biological purification, filtration, and deodorization.

[0003] Existing self-sinking bio-adsorption ball wastewater treatment packing materials are generally produced in one piece through injection molding. Their structure is relatively simple, with weak microbial adhesion and small specific surface area, which is not conducive to microbial biofilm formation and results in low microbial metabolic efficiency, thus leading to poor wastewater treatment efficiency of the packing material. Therefore, a self-sinking bio-adsorption ball wastewater treatment packing material is proposed to address the above problems. Utility Model Content
