Abstract

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 moreover, the incoming water is sufficiently oxygenated, uniform oxygenation at each part in the biological filter is guaranteed, and the pollutant removal rate is obviously improved.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a biological filter. Background technique [0002] Various biological aerated filters exist, such as figure 1 Shown: Biological aeration filter includes: water distribution tank 1, single-hole membrane air diffuser 2, backwash water inlet pipe 3, backwash inlet pipe 4, filter head 5, aeration pipe 6, backwash drain pipe 7, normal Drainage pipe 8, biological filter material 9, the water is pumped to the water distribution tank 1 through the pump, and enters the biological filter tank from the bottom through the water distribution pipe, and the water flows from bottom to top. The water is discharged from the normal drainage pipe 8. During this process, the blower needs to be started to provide air to the biofilter through the aeration pipe 6 and the single-hole membrane air diffuser 2. [0003] The existing biological aerated filter has the following deficiencies: ...
