A kind of microculture filter medium structure,The microculture filter material system includes: a weight ratio accounts for 84% ~ 90% and seeks connections with body,The mixed composition of adhesion layer for accounting for 10% ~ 16% with a weight ratio； Wherein this seeks connections with the fine particle that system accounts for 30% with a plurality of weight ratio,And a plurality of weight ratio account for 70% coarseparticulate and are mutually mixed and present； And it is coated with the adhesion layer between what a plurality of fine particles and a plurality of coarseparticulates,The microculture filter material of a solid-type is formed through the cemented mode of sintering again,And make that there are a plurality of hole slots not of uniform size at the microculture filter material outer rim,Growth is sought connections with microbial digestion bacterium generated in watering by each hole slot not of uniform size is presented at the microculture filter material outer rim,Thereby,The effect of in order to reaching reduction more quantity of exchanged water number and maintaining water stabilization.一種微生物培養濾材結構，該微生物培養濾材係包含：一重量比例佔84%~90%之攀附體，與一重量比例佔10%~16%之黏著層所混合組成；其中該攀附體係具有複數個重量比例佔30%之細顆粒物，及複數個重量比例佔70%之粗顆粒物所相互混合而呈現；並於該複數個細顆粒物與複數個粗顆粒物間塗設該黏著層，再透過燒結黏固方式而形成一固體型態之微生物培養濾材，且使該微生物培養濾材外緣處具有複數個大小不一致之孔槽，藉由該微生物培養濾材外緣處所呈現各大小不一致之孔槽以供水源內所產生的微生物消化菌予以攀附生長，藉此，俾達到減少更換水量次數且維持水質穩定之功效。
