Abstract

The invention discloses a floating biofiltration backwashing apparatus, and belongs to the technical field of sewage treatment. The floating biofiltration backwashing apparatus comprises a pool body and a treatment tank, the treatment tank is filled with a granular floating filler to form a filter layer, the apparatus also comprises a backwashing water outlet tube, a backwashing water sprinkling tube, a backwashing sludge discharging tube, a backwashing gas inlet tube, an air chamber, an air releasing mechanism, a backwashing gas source and a sludge lift pump, the air chamber is arranged at the bottom of the pool body, the backwashing gas source is communicated with the air chamber through the backwashing gas inlet tube, the air releasing mechanism is arranged in the air chamber, the outlet of the backwashing water outlet tube and the backwashing water sprinkling tube are sequentially arranged over the treatment tank from top to bottom, and the sludge lift pump is arranged at the bottom of the backwashing sludge discharging tube. The apparatus uses a normal-running fan or gas compressor, and utilizes air instantaneously jetted by the air chamber to rapidly decrease water flow in order to realize sludge and filler separation and reach the backwashing purpose, so the apparatus investment is reduced, and the energy consumption is also reduced.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and relates to a floating organism filtering and backwashing device. Background technique [0002] The floating biological filter is a new type of sewage treatment technology. Compared with the traditional sewage treatment process, it has many advantages such as less investment in infrastructure, low operating costs, small footprint, and convenient management. It is a sewage treatment equipment integrating biodegradation and solid-liquid separation. Sewage enters the bottom of the filter, and treated water flows out the top. Three layers are formed in the filter tank, which are in order from bottom to top: sewage sedimentation layer, filtration separation layer, treated water storage layer, filter separation layer is filled with filter material, biofilm grows on the surface of filter material, aeration inside the filter tank, sewage flow Over time, the sewage can be quickly purified by...
