Embodiment:
The utility model comprises bio-reactor (P1), service pump (P2), recycle pump (P3), tubular membrane component (P4), gas pipe (P5), air compressor (P6), backwashing pump (P7), dosing pump (P8) and many group operated pneumatic valve (V1, V2 ... V8); Water in the bio-reactor (P1) after biological treatment is through service pump (P2) → recycle pump (P3) → operated pneumatic valve (V1) → water-in (1) → water distributing pore (13) → film pipe (10) → product mouth of a river (4) → operated pneumatic valve (V8) → clean water basin; Water outlet/air outlet (3) → operated pneumatic valve (V6) → bio-reactor (P1), emptier; Water-in (1) → operated pneumatic valve (V5) → backwash blow-off pipe → bio-reactor (P1); Air is through the inlet mouth (2) of air compressor (P6) compression one tunnel → operated pneumatic valve (V2) → tubular membrane component (P4), one tunnel → operated pneumatic valve (V4) → operated pneumatic valve (V3, V7, V8) → product water out (4); Clean water basin → backwashing pump (P7) → operated pneumatic valve (V3); Dosing tank → dosing pump (P8) → operated pneumatic valve (V7); Tubular membrane component (P4) is that a vertical drum shape shell (5) adds, lower cover (6,7) is used, lower seal (8,9) sealed whole; Upper cover (6) is provided with and produces water out (4) and water outlet/air outlet (3); Lower cover (7) is provided with water-in (1) and inlet mouth (2); Air distribution plate (15), qi-emitting hole (14) and film pipe (10) vertically are set in the shell (5), some water distribution/qi-emitting holes of arranged transversely (12) and water distributing pore (13), the centre is provided with plug (11).Film pipe (10) is made up of basement membrane and pellicle; Basement membrane is formed by the ultrahigh molecular weight polyethylene(UHMWPE) sintering of sintering process preparation, and pellicle is a polyvinylidene difluoride (PVDF).A gas pipe with the superhigh molecular weight polyethylene material sinter molding (P5) is equipped with in tubular membrane component (P4) bottom.
Basement membrane forms firm combining with pellicle, makes film pipe (10) can tolerate higher backwashing pressure (0.5MPa), and simultaneously, above-mentioned two kinds of materials all have powerful oxidation corrosion resistance, strong acid, alkaline ability.Comprehensive above-mentioned advantage, film pipe (1) helps quick on-line cleaning, thereby in high density, full-bodied water body filter, remains the continous-stable operation.
The gentle tolerance that provides of formation that tubular membrane component (P4) gas is carried: the design of gas pipe (P5) must be decided according to the packing density of tubular membrane inner membrance pipe.Formed bubble is not the smaller the better, and bubble must suitably can play scrubbing action between film pipe (10) space.The air demand of each tubular membrane component (P4) is at 0-20Nm3/h; Gas pressure-raising power＜0.05MPa is advisable.
Tubular membrane component (P4) working order:
1, filter:
When filtering, service pump (2) is sent the mixed solution in the biochemical reactor (1) into tubular membrane component (P4), and service pump (P2) is used to keep the constant flooding velocity, improves flow velocity through recycle pump (P3) and flows to the top from tubular membrane component (P4) bottom; Pressurized air compresses after the gas pipe of bottom (P5) is sent into even air in the cavity of tubular membrane component (P4) through air compressor (P6).Because the rising of air drives, driving mixed solution and suspended solids rises, keep certain flow velocity (1-3m/s) on film pipe (10) surface, air agitation is cleaned the film surface, take away the suspended particle and the colloid that cause film to pollute easily and stop up, mixed solution flows with the cross-flow form, is trapped within the film surface greater than the particle and the solute of fenestra, and make water be purified less than the seeing through membranous wall of fenestra, realize solid-liquid separation.Product water multiparity water out (4) after the purification, operated pneumatic valve (V8) enters clean water basin.Owing to be cross flow filter, dense water is got back to biochemical reactor (P1) through operated pneumatic valve (V6), makes that sludge concentration constantly increases in the biochemical reactor (P1), helps the organic matter degradation that further difficulty decomposed, thereby improves biochemical effect; Air is through the emptying of emptying pipeline.
2, backwash:
In equipment running process, mud accumulates in the surface and fenestra of inner chamber, film pipe (10) of tubular membrane component (P4), is the normal operation that keeps system.These pollutents must regularly be discharged by back flushing.
In the backwash process, open air compressor (P6), oil-free compressed air is through operated pneumatic valve (V4), product water out (4) enters in the chamber of tubular membrane component (P4) from the opposite direction of membrane filtration, its recoil pressure 0.5MPa, successive pulse formula back flushing 2-3 time, each time is 2-3 second.After the gas recoil, open the product water backwash 1-2min in backwashing pump (P7) the usefulness clean water basin again, process is: backwashing pump (P7) draws water from clean water basin and enters in the chamber of tubular membrane component (P4) from producing water out (4), flows out from water-in (1), gets back to biochemical reactor (P1) through the backwash blow-off pipe.At normal gas recoil, water backwash 15-20 all after dates, need strengthen backwash, promptly in the water backwash, add chemical agent carries out 10-15min to tubular membrane component (P4) immersion and cleaning by volume pump (8).Generally during 30-45 days, also need tubular membrane component (P4) is carried out matting completely, to recover the original flux of tubular membrane component (P4).
