The invention relates to a biofilter which comprises a biological filter for containing biological filler, a water inlet pipeline, an ejector, a lifting pump and a water outlet pipeline, wherein a water inlet and a water outlet extending from the top of the biological filter into the biological filter are formed at the two ends of the water inlet pipeline respectively; the ejector is used for oxygenating water entering the water inlet pipeline and is arranged on the water inlet pipeline; the lifting pump is used for increasing pressure of the water entering the water inlet pipeline and is arranged at the water inlet of the water inlet pipeline; and the water outlet pipeline is communicated with the water outlet at the bottom of the biological filter. The biofilter provided by the invention has the beneficial effects that the problem that an independent aeration device is required in the prior art is solved by adopting the ejector, and the construction cost and the maintenance cost are remarkably reduced; and
