Described curtain formula tubular fibre diaphragm is made up of hollow-fibre membrane silk 17 and sheath 16, and the hollow-fibre membrane silk is a kind of tunica fibrosa with mesopore, is thick with size and is＜0.2 micron microvoid structure on membranous wall.
Principle of work of the present invention is as follows:
The present invention is according to the membrane bioreactor basic functional principle, be sewage to be carried out biochemical treatment by traditional activated sludge process, reduce organic contamination content in the sewage, utilize hollow-fibre membrane separation characteristic efficiently again, from muddy water, isolate clean water, the needs that satisfy discharged wastewater met the national standard or utilize again.
The sanitary wastewater that the sewage kind that the present invention is fit to mainly is can be biochemical, pollution level is not high or the trade effluent in fields such as other food, beverage.COD in the waste water
CrAt 200-1000Mg/L, BOD
5About 100-600mg/L.The water quality of water outlet can reach national sanitary sewage disposal first discharge standard, perhaps is used to flush the toilet, reclaimed water standard such as greening the COD of water outlet
Cr＜30Mg/L, BOD
5＜20mg/L, NH3-N＜10mg/L, SS＜2mg/L.
Working process of the present invention is:
(1), after original sewage promotes through sewage pump, inject the pre-exposure gas area earlier, in the pre-exposure gas area, sewage is through the first step biochemical treatment, and macromolecular organism is decomposed, the COD in the sewage
CrAnd BOD
5Clearance can reach about 30%～40%.It mainly is for the ease of the active sludge growth that elastic filler is set in the pre-exposure gas area, and in this bottom, district aerator being set mainly is that sewage is carried out aeration, and the aeration main purpose is a dissolved oxygen in sewage, guarantees the carrying out of biochemical treatment.It is more even that elastic filler can also make active sludge distribute, and active sludge is more abundant with mixing of sewage.
Be provided with upper and lower two liquid level switches in the pre-exposure gas area, when water level was higher than liquid level, sewage pump quit work, and when water level was lower than liquid level, sewage pump was started working.The flow of sewage pump should be set according to the amount of disposing of sewage day by day, and is suitable with the flow of vacuum primingpump, thereby assurance device can evenly feed water.
(2), sewage through after the preliminary biochemical treatment, enters membrane biological reaction district by the overflow mode in the pre-exposure gas area.The membrane biological reaction district is main biochemical treatment district, and most organic pollutant is here effectively removed.Curtain formula tubular fibre diaphragm is installed on the diaphragm erecting frame in this district, and curtain formula tubular fibre diaphragm links to each other with vacuum primingpump by the clear water header.Curtain formula tubular fibre diaphragm is immersed among the sewage, the suction force of vacuum primingpump forms pressure difference between the inner and outer wall of hollow-fibre membrane, because hollow-fibre membrane is stalling characteristic efficiently, clear water can see through the micropore of membranous wall, and outside clear water collection tube overboard pump, and macromolecule contaminant and active sludge are because particle diameter is bigger, can not see through the micropore on the membranous wall, intercepted, stayed the membrane biological reaction district, proceeded biochemical treatment.
Be provided with aerator in diaphragm erecting frame bottom, aerator links to each other with blower fan, and sewage is carried out aeration.On the one hand, aeration can be in sewage dissolved oxygen, promote the aerobe bulk-growth, the organic contamination in the degradation of sewage.On the other hand, the current that make progress that aeration forms form flushing to curtain formula tubular fibre diaphragm, and this cross-flow effect can impel the sludge concentration of film outer surface no longer to raise, and guarantee the long-term steady running of curtain formula hollow-fibre membrane sheet.
For guaranteeing curtain formula tubular fibre diaphragm water outlet operation steady in a long-term, vacuum primingpump is taked discontinuous work way, and every work 10～20 minutes stops 2～5 minutes.This method of work also can stop the deposition of mud at membranous wall, reduces the pollution of film, improves the work-ing life of curtain formula tubular fibre diaphragm
Be provided with liquid level switch down in the membrane biological reaction district, when water level was lower than this liquid level, vacuum primingpump quit work, and when water level was higher than this liquid level, vacuum primingpump was started working.
(3), in the out-of-work gap of vacuum primingpump, the film backwashing pump injects curtain formula tubular fibre diaphragm with scavenging solution by accurate filter, hollow-fibre membrane is carried out from inside to outside back flushing, thereby more effectively remove the pollutent on striping surface.Scavenging solution can be clear water or chemical.
(4) apparatus of the present invention adopt full automatic control,, sewage pump starts and stops, vacuum primingpump starts and stop, and recoil time of vacuum primingpump discontinuous operating mode, film backwashing pump or the like, all realizes that by PLC time parameter can also be adjusted.
(5), this device also is provided with overflow port and sewage draining exit, when equipment occurs when unexpected, overflow port can be discharged unnecessary sewage.After operation for some time, active sludge may wear out at this device, and residual active sludge may produce, and can carry out suitable spoil disposal by sewage draining exit.It is fixed that but concrete spoil disposal number of times and output will be come according to sewage disposal running condition.
(6) this device externally mainly is provided with 3 Link Ports, is specially: dirty mouthful inlet, clear water output, film back flushing cleaning liquid inlet.
Determining of design variable of the present invention:
(1), pre-exposure gas area and membrane biological reaction district volume size determines.
Pre-exposure gas area and membrane biological reaction district volume size be mainly by the decision of sewage character and pollution level, if when sewage organic contamination substrate concentration is higher, the useful volume in pre-exposure gas area and membrane biological reaction district needs to increase, and water retention time is just longer.The water retention time of pre-exposure gas area is typically designed to 2 to 6 hours, and flexible the setting up of the water retention time in membrane biological reaction district counted 6 to 12 hours.
Calculating means:
The Q=amount of disposing of sewage every day (m
3/ d)
Q=is the amount of disposing of sewage (m per hour
3/ h)
Pre-exposure gas area useful volume=q * (2～6) m
3
Membrane biological reaction district useful volume=q * (6～12) m
3
(2), determining of curtain formula tubular fibre diaphragm quantity:
The curtain formula tubular fibre diaphragm of selecting for use, every diaphragm-operated membrane area is 8～10m
2, designing the water yield is 1.0～1.2m
3/ day.
Curtain formula tubular fibre diaphragm quantity=Q/ (1.0～1.2) sheet
(3), determining of vacuum primingpump operating pressure:
Curtain formula tubular fibre diaphragm relies on the extraction negative pressure of vacuum primingpump as motivating force, and the works better negative pressure is: 0.02～0.05Mpa.When work negative pressure during greater than 0.05Mpa, aquifer yield will show that the damage ratio of curtain formula tubular fibre diaphragm is more serious less than should treatment capacity, should clean or change.
(4), film back flushing working parameter is determined:
Film backwashing pump operating pressure is answered＜0.1Mpa, and the back flushing fluid volume is answered＜2 times the normal aquifer yield of curtain formula tubular fibre diaphragm.
The filtration precision of accurate filter should be less than 5 microns, and scavenging solution is the water outlet of curtain formula tubular fibre diaphragm or the mixed solution that adds clean-out system.
