Description
Technical field
The invention belongs to water-treatment technology field, particularly relate to a kind of membrane biological processor.
Background technology
During at present with the particularly dirty waste water of tubular fibre film group device treating water, there are some defectives, first, because aeration is inhomogeneous, easily produce the air water short circuit phenomenon, gas-water mixture is insufficient to the souring on hollow-fibre membrane surface, causes the alluvial of hollow-fibre membrane surface contaminant, blocks the hollow-fibre membrane surface; The second, microorganism lacks suitable " nest "---bio-carrier in the tubular fibre film group device, limited the microbial growth breeding; The 3rd, rupture and twine owing to significantly swinging appears under the air water effect in some hollow-fibre membrane silk, cause that effluent quality descends; The 4th, because utilizing of gas is insufficient, cause the air feed energy consumption to increase.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of filled membrane biological processor is provided.
Technical scheme of the present invention is summarized as follows:
Filled membrane biological processor, comprise water treatment vessels, hollow-fibre membrane group, aeration pipe network, main and support catchment, described hollow-fibre membrane group is made up of tubular fibre diaphragm and header, is provided with suspensoid in the described water treatment vessels, and the density of described suspensoid is 0.9-1.0g/cm
3, described suspensoid is made up of perforated shell and weighting material, and the material of described perforated shell is polypropylene or polyethylene, and described weighting material is at least a in activated carbon fiber, activated carbon granule, polypropylene fibre, the polyethylene fiber peacekeeping ion exchange resin.
Described hollow-fibre membrane group top is provided with the porous plate washer.
Described suspensoid is at least a in spherule, cylinder, polygon prism shape body, dihexahedron, dioctahedron, square, rectangular parallelepiped and the olive shape body.
The length of described suspensoid or diameter are 3mm-40mm.
The surface of described perforated shell is provided with projection.
Advantage of the present invention:
1. because the setting of suspensoid, for the microorganism in the water treatment vessels provides good growing carrier, particularly huge surface area that weighting material had and structure, cause weighting material from showing to the lining, aerobic, the anaerobic of growing accordingly helps the removal of pollutents such as organic degraded and ammonia nitrogen to the anaerobic microbial population.
2. blow down at gas, the suspensoid motion because the corner angle of suspensoid or the setting of rat are beneficial to the cleaning of the outside surface of the hollow-fibre membrane of forming the tubular fibre diaphragm, has reduced the alluvial of hollow-fibre membrane surface contaminant.
3. be filled in tubular fibre diaphragm suspensoid on every side, can prevent the significantly swing that hollow-fibre membrane occurs under the air water effect, avoided the fracture and the winding of hollow-fibre membrane.
4. when the suspensoid between the tubular fibre diaphragm can make bubble run into suspensoid, the space between suspensoid of need detouring helped the distribution of gas, has avoided the air water short circuit phenomenon.
5. because making full use of of gas reduced gas-water ratio and energy consumption.

Embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
Filled membrane biological processor, comprise water treatment vessels 1, hollow-fibre membrane group, aeration pipe network 2, main 3 and support 4 catchment, the hollow-fibre membrane group is made up of tubular fibre diaphragm 5 and header 6, is provided with suspensoid in the water treatment vessels, and the density of suspensoid is 0.9-1.0g/cm
3Suspensoid is made up of perforated shell 9 and weighting material 10, the hole is 11, and the material of perforated shell is polypropylene or polyethylene, and weighting material is at least a in activated carbon fiber with huge surface area, activated carbon granule, polypropylene fibre, the polyethylene fiber peacekeeping ion exchange resin.
Above the hollow-fibre membrane group, preferably be provided with the porous plate washer.
Suspensoid is at least a in spherule, cylinder, polygon prism shape body, dihexahedron, dioctahedron, square, rectangular parallelepiped and the olive shape body, is preferably spherule.
The length of suspensoid or diameter can select 3mm, or 5mm, or 10mm, or 30mm, or 40mm, better are 15mm, or 20mm, or 25mm or 30mm.
The surface of perforated shell is provided with projection 12.
By changing the consumption of perforated shell inner stuffing, can make the density of the density of suspensoid near pending water, suspensoid can just be suspended in water.The density of suspensoid can be 0.9g/cm
