Abstract
The utility model relates to a carrier fluidized plate membrane bioreactor which comprises an adjusting tank, a fluidized filler aeration tank, a compartment, a plate membrane bio-aeration tank, a product water storage tank and a sludge tank. The fluidized filler aeration tank is arranged in the front of the compartment. The plate membrane bio-aeration tank is disposed at the rear of the compartment. The carrier fluidized plate membrane bioreactor is characterized in that the bioreactor is an integral bioreactor composed of fluidized biofilm filler and an immersed plate film. The carrier fluidized plate membrane bioreactor is applicable to treatment and recovery of high-concentration COD (chemical oxygen demand) (1000-5000mg/L) industrial wastewater, and operational cost can be lowered effectively.
Description
Technical field
The utility model belongs to the environmental chemical engineering equipment technical field, in particular to a kind of carrier fluidized plate membrane bioreactor of handling waste water.
Background technology
Often the water yield is big for trade effluent (like paper waste, refinery water and coking chemical waste water), and the organic contamination substrate concentration is high, complicated component, and biological degraded fast is difficulty very.Tradition aerobic aeration activated sludge process can effectively be removed COD, if but come water COD concentration to be higher than 1000, aeration rate increases, and oxygen transfer efficiency descends, and running cost increases.The plate membrane bioreactor sludge concentration is high, removes COD, and it is good to hold back SS and microorganism effect, but when coming water COD concentration higher, membrane module is contaminated easily, and running cost increases.
The utility model content
The purpose of the utility model provides processing and the reuse that is applicable to high concentration COD (1000-5000mg/L) trade effluent, can effectively reduce the running cost waste water treatment reactor.
In order to realize above purpose, the utility model adopts following technical scheme.
The utility model relates in one aspect to a kind of carrier fluidized plate membrane bioreactor of handling waste water; Comprise: the storage pool and the sludge sump of equalizing tank, fluidized padding aeration pond, partition chamber, flat sheet membrane bio-aeration pool, product water; Cutting off the front portion, chamber is fluidized padding aeration pond, and cutting off the rear portion, chamber is the flat sheet membrane bio-aeration pool; It is characterized in that the integral bio reactor drum formed by fluidized biofilm packing and immersion flat sheet membrane.
In a preferred implementation of the utility model, described carrier fluidized biofilm reactor the inside is filled with the fluidized filler, and packing density is between 0.9-1g/L, and the filler filling ratio is the 20-70% of aeration tank useful volume.
In a preferred implementation of the utility model, one group of 100-180m of described flat sheet membrane
2/ m
3, to fix with high-density polyethylene material, filling ratio is the 40-60% of flat sheet membrane bio-aeration pool useful volume, membrane pore size＜1um.
In a preferred implementation of the utility model, perforated pipe aerating regulation is all adopted in described two aeration tanks, bottom, aeration tank, fluidized filler pond aeration tube perforate 1-9mm, and aeration tube, perforate 0.5-4mm are established in bottom, flat sheet membrane aeration tank.
Add a fluidized carrier biofilm padding aeration pond in the plate membrane bioreactor front portion; Not only can accept high-concentration industrial and come water COD concentration 1000-5000, the biofilm packing of fluidized can also increase oxygen transfer efficiency, energy-conservation 10-20%; Control DO, pH, temperature and C/N ratio simultaneously; Can also realize digestion and denitrification denitrogenation synchronously, alleviate the burden of subsequent film bio-reactor simultaneously, make the more valuable membrane module life-span prolong.The immobilization material of plate film assembly uses the high density polyethylene(HDPE) of modification, makes it both hard, can flow down slight vibration at water aeration again, has slowed down pollution and the obstruction of mud to film, improves overall system efficiency.
