AI Technical Summary
Existing biological packing materials have poor biocompatibility, resulting in low effective degradation bacteria concentration per unit volume, slow reactor start-up, easy loss, poor resistance to toxicity, and sensitivity to changes in hydraulic conditions.
A bio-filler was formed by polymerizing chitosan and acrylic acid, using mesoporous silica and hydrofluoric acid as template agents and detemplating agents, and introducing an electrolytic reaction solution of 1-butylpyridine chloride and aluminum sulfate as an initiator to form a polymer with well-developed pores and high structural strength.
It increases the colonization rate of microorganisms and the structural stability of biological packing materials, enhances the growth space for microorganisms, significantly improves wastewater treatment efficiency, and maintains structural stability under high pressure conditions.
