Gutta-percha-modified biofilm filler and its preparation method and application

The invention discloses a gutta-percha-modified biofilm filler and its preparation method and application. Natural gutta-percha is sprayed on the surface of a traditional biofilm filler through the solution jet technology, surface modification is conducted on the biofilm filler prepared from inert polymers, and the loading effect of biofilm filler is enhanced; after quick-drying molding, the modified biofilm filler has hydrophilicity and biophilicity, can effectively improve such shortcomings of a traditional suspended biofilm filler that on-surface formed biofilms are little, the impact loadresistance is low, the adhesion force of the biofilms is not enough and the biofilm formation time is long, and can be applied in the biofilm technology suitable for industrial and municipal sewage treatment. The adopted gutta-percha as raw materials is widely planted in China and low in technologic application cost, condition requirements of the preparation technology are simple, the preparationtime is short, and the gut
