Abstract
The utility model relates to an integrated baffle type anaerobic/anoxic/aerobic membrane filtration high-concentration organic wastewater treatment device. The integrated baffle type anaerobic/anoxic/aerobic membrane filtration high-concentration organic wastewater treatment device mainly comprises a sewage pool, a one-way flow type ABR (Anaerobic Baffled Reactor), an up-flow type anoxic pool with a stirrer, an up-flow type aerobic pool, a sedimentation pool, an up-flow type MF (Micro-filtration Membrane Filtration) pool and the like, wherein fillers in two reaction pools (19 and 21) are elastic fillers; an annular micro-pore aeration device is arranged in the middle of the bottom of the pool (21), so that water flow can be in a fluidized state, microorganisms, the water flow and the air are in full contact with one another, and nitration, phosphorus accumulation and full degradation on organic pollutants are realized. According to the device, the process advantages of an ABR (anaerobic baffled reactor) process, a biological membrane method, an A<2>/O (anaerobic/anoxic/aerobic) process, an MF process and the like are combined. The device has the advantages of stable effluent quality, good simplicity in operation and management, small occupied area, low operating cost and the like.
