Section region, and when entrance enters from below, it, can be to avoid the impurity that will filter or handle generation later due to gravity
Bring next region into, improve each region to the processing capacity of sewage, at the same diversion pipe be close to each region partition setting and
Entering water, Open Side Down, so that floating stuffing, which can not be blocked directly, enters the opening of water in diversion pipe, also avoids floating stuffing stifled
Plug is at transmission mouth；The setting of return pipe so that sewage can multiple circular treatment, to reach better clean-up effect.
The present invention is further arranged to: airlift pump is provided on the return pipe, the air that the airlift pump generates leads to
Air hose, the air hose are provided with the aeration tube towards aerobic zone bottom, and the one end of the aeration tube far from air hose is circle
It is cyclic annular.
By using above-mentioned technical proposal, airlift pump provides power for the sewage backflow of return pipe, and equipment pipe is simple, nothing
Transmission parts, no Awaiting Parts and high reliablity, while can provide air for air hose are the micro- of regulatory region and aerobic zone
Biology provides enough oxygen and generates turbulent flow；The aeration tube of aerobic zone annular have bigger outlet area, while
Oxygen concentration in aerobic zone is also more uniform, guarantees that the microorganism growing way in floating stuffing is close, avoids filtering uneven.
The present invention is further arranged to: being provided with overflow launder between the diversion pipe III and outlet pipe.
By using above-mentioned technical proposal, in sewage after anaerobic zone, first reach overflow launder, a part of liquid from
Water outlet discharge, a part are discharged from overflow port, and the liquid after overflow port discharge reaches regulatory region and carries out circulating filtration, thus
Improve the wastewater treatment efficiency of fluidized bed.
The present invention is further arranged to: the circulating filtration area is provided with supporting plate, is provided with fibrous nodules on supporting plate and fills out
Material, the anaerobic zone and aerobic zone are provided with the filler cover board for preventing filler from losing.
By using above-mentioned technical proposal, the installation for being set as fibrous nodules filler of supporting plate provides position, fibrous nodules
Elasticity is good for filler, is able to maintain shape under water impact, it is not easy to damage, will not float to the water surface, gap is larger, water flow loss
It is smaller, and fibre strength is higher, and service life is longer；Filler cover board can avoid the filler hair for being located at aerobic zone and anaerobic zone
Raw leakage guarantees the stabilization of filler quantity in aerobic zone and anaerobic zone, and micro organism quantity is stablized, and more preferably can filter and handle dirt
Water.
The present invention is further arranged to: the fibrous nodules filler uses polytetrafluoroethylene fibre.
By using above-mentioned technical proposal, fluorine atom volume is larger in the molecular structure of polytetrafluoroethylene (PTFE), the knot of fluorine carbon key
It is larger with joint efforts, so that polytetrafluoroethylene (PTFE) chemical stability with higher, corrosion-resistant, in the fluidized bed course of work, microorganism
Concentration in sewage is higher, corrosion-resistant to improve the service life of filtrate, fiber surface friction system to avoid the damage of filtrate
Number is small, and fibrous nodules filler is more convenient when cleaning；The polytetrafluoro that the polytetrafluoroethylene (PTFE) used is modified for carbon fiber and glass fibre
Ethylene has higher intensity.
The present invention is further arranged to: the floating stuffing includes polyurethane matrix and polyethylene backbone, the polyurethane
