MICROORGANISM-LOADED 3D PRINTING MATERIAL FOR HEAVY METAL SEWAGE TREATMENT, PREPARATION METHOD THEREFOR, AND USE THEREOF

摘要

Disclosed are a microorganism-loaded 3D printing material for a heavy metal sewage treatment, a preparation method therefor, and the use thereof, which solve the technical problem that the biological treatment effect of heavy metal wastewater is weakened due to the shortcomings of existing biological fillers in the process of treating heavy metal sewage using existing microorganisms. The 3D printing material has a double-layer solid core composite monofilament structure, which is composed of an inner core layer and an outer surface layer, wherein the outer surface layer is coated on and connected to the surface of the inner core layer; the inner core layer is a microorganism-loaded gel layer composed of fenugreek gum, Caesalpinia spinosa gum, mantis egg-case, carbonized ginger, a microbial agent and deionized water; and the outer surface layer is a hard layer composed of polycaprolactone, polyethylene glycol and a magnetic liposome. Further disclosed are a method for preparing a microorganism-loaded 3D printing material for a heavy metal sewage treatment according to a raw material ratio, and the use thereof. The material can be widely used in the technical field of wastewater treatment materials.
