A respirator for measuring a respiratory rate of a biofilm includes a body, a carbon dioxide absorption tube and a perforated partition disposed in an interior of the body. The perforated partition divides the interior of the body into an oxygen mass-transfer stir zone including a stirring device and a biofilm reaction zone for placing MBBR fillers. The carbon dioxide absorption tube includes an air vent and contains a solution capable of absorbing CO. The perforated partition has a first hole corresponding to a middle portion and a lower portion of the perforated partition and acting as a liquid-exchange channel, and a second hole corresponding to an upper portion of the perforated partition and acting as a gas-exchange channel, and the oxygen mass-transfer stir zone is communicated with the biofilm reaction zone through the liquid-exchange channel and the gas-exchange channel.
