Radioactive water treatment biological filling

The utility model provides a radioactive water treatment biological filling which is provided with two fixed sleeves, a plurality of thread bodies, and braid fixing threads. The two ends of the thread bodies are respectively fixed on the two tubular fixed sleeves corresponding to the thread bodies by the braid fixing threads. The characteristics of the radioactive water treatment biological filling are as follows: each thread body is respectively provided with vertical thread bodies woven by a plurality of chemical synthetic fiber yarns with the hydrophobic property, and a plurality of transverse thread bodies made of chemical synthetic fiber yarns with the hydrophilic property; the transverse thread bodies are independently arranged; each transverse thread bodies in each thread body is respectively woven with each vertical thread body at the middle position, so as to lead the transverse thread bodies to present a radioactive thread-shaped structure. With large specific surface area, high void ratio, low wate
