The present invention provides a floated biological treatment apparatus and a process for purifying refractory wastewater or raw water for drinking water. The treatment apparatus of the present invention includes a supporting plate for dividing the treatment apparatus into upper and lower portions. The upper portion is formed into a reactor, and porous compressible carriers are filled with the reactor in an amount of 80 vol % to 100 vol % of the reactor volume. The lower portion is provided with a liquid inlet for introducing the refractory wastewater or raw water and a gas inlet. The reactor is provided with at least one top carrier blocking plate at the top, such that the carriers can be limited by the top carrier blocking plate to be retained in the reactor, and the carriers can become a floating state. By means of the process or apparatus of the present invention, the cost for treating refractory organic material can be reduced, the treatment efficiency can be enhanced, and the quality of the effluent can be improved. In addition, since the carriers are in a floating state, they will have the advantages of low abrasion. The clogging problems can be prevented, and the gas and the influent can be evenly distributed.
