Water treatment device in FBMBR (fluidized bed membrane bioreactor)

The invention provides a water treatment device in an FBMBR, which comprises an anoxic tank, an FBMBR (fluidized bed membrane bioreactor) biochemical reaction tank and a clean water disinfection tank which are connected sequentially. The FBMBR biochemical reaction tank is connected with a sludge digestion tank. The water treatment device further comprises a suction pump. The treated sewage is sent to the biochemical reaction tank by the anoxic tank through automatic flow. The water treated by the biochemical reaction tank is pumped into the clean water disinfection tank for disinfection treatment by the suction pump through a membrane module. The water treatment device can be widely applied to the fields of reclaimed water treatment and recycled water treatment.
