[detailed description of the invention]
Hereinafter, being described further for the present invention with accompanying drawing, embodiment and accompanying drawing are only used for explaining in conjunction with the embodiments
Bright rather than limit protection scope of the present invention.
Biological solid-carrying type film biological unit reactor primary structure in the present embodiment includes cell body, bio-carrier, film group
Part, high-efficiency strain, aerator, cell body, interception net, protection network, pump.Bio-carrier is mainly used in loading high-efficiency strain；Film group
Part is mainly used in retaining macromolecular substances and high-efficiency strain, it is ensured that the delivery turbidity of waste water；High-efficiency strain be through special domestication,
After screening, by transport pump to biological solid-carrying type film biological unit reactor, and it is attached on bio-carrier；Aerator position
In biological solid-carrying type film biological unit reactor bottom, carry a certain amount of air by air compressor and enter membrane biological reaction
Device, for the oxygen that the biodegradation offer of high efficiency flora is enough, washes away a small amount of attachment being attached to film silk surface simultaneously；Cell body
It is mainly used in carrying the materials such as bio-carrier, membrane module, high-efficiency strain, aerator, interception net, protection network, waste water, belongs to and set
Standby agent structure；Intercept net and be used for retaining the bio-carrier of flowing, prevent face, bio-carrier emersion pond or sink at the bottom of pond；Anti-
On the one hand protecting wire net is used for intercepting bio-carrier, prevents bio-carrier from entering membrane module；On the other hand maintenance it is prone to, when equipment needs
During maintenance, dismount certain several unit therein and have no effect on.
As it is shown in figure 1, include in cell body that multiple film units of following structure and filler unit are disposed adjacent and form, adjacent
Separated by protection network between unit, all separated by filler unit between film unit and film unit, film unit and filler unit
Positive six prisms are surrounded by protection network,
A. film unit, side surrounded by described protection network and forms, be internally provided with membrane module, and membrane module includes hollow posts
The fibrous membrane of shape, fibrous membrane is coated with housing, and housing side is distributed the hole that waste water can be allowed to pass through, and housing is positioned in cylindricality
It is sealedly connected with outlet conduit on empty position,
B. filler unit, side surrounded by described protection network and forms, and bottom is provided with interception net, and inside is filled with multiple
Bio-carrier.
Separate with packing area with the form of separate unit, it is simple to separating of membrane module is overhauled or changed.This equipment complex
ABFT, membrane filtration, the advantage of immobilized microorganism technique, not only save second pond, reduces floor space, and
And extend the waste water time of staying in biological solid-carrying type film biological unit reactor, make waste water fully connect with bio-carrier
Touch, in the case of ensureing stably reaching standard water outlet, reduce investment and operating cost.
As shown in Fig. 1～2, in the present embodiment, bio-carrier and membrane module are honeycomb arrangement, and this arrangement mode not only saves
Save floor space, and the loss of high-efficiency strain can have been reduced, improve purification efficiency.The material of bio-carrier can be many
Hole pottery, activated carbon, polyurethane or PVA etc., particle diameter is between 1～3cm, and pore-size distribution is reasonable, voidage is high, specific surface area
Greatly, having that good hydrophilic, biological affinity be strong, chemical stability, good mechanical property, carrier is stereo hollow structure, outward
Peripheral band tooth, tooth depth ≮ 1mm, inside and outside have three layers of open circles.High-efficiency strain after activation pumps into biological solid-carrying type film biology list
Elementary reaction device, uses microorganism curing technology to be attached on bio-carrier by high-efficiency strain, and forms one layer of aerobic biologic membrane.Gu
Surely changing microbial technique is free cell or enzyme to be fixed by chemistry or physical means, makes water-insoluble
But still there is bioactive derivant.High-efficiency strain can be firmly fixed on bio-carrier by this combination,
And difficult drop-off and loss.High-efficiency strain is to have the excellent of specific function by add from nature screening in system
Gesture strain or produced by assortment of genes technology.High-efficiency strain biology solid-carrying type film is pumped into by after induction the 1/4 of high-efficiency strain
Biological unit reactor, after soaking 4h, again adds culture medium once by 1/4 of the high-efficiency strain after induction every 4h, by several times will
Bacterium solution pumps into biological solid-carrying type film biological unit reactor；Through repeatedly adding the immersion of bacterium solution and 48h, porous active high-area carbon
To the absorbtivity of bacterium already close to time saturated, complete the immobilization (such as the patent No.: ZL201120520934.X) of high-efficiency strain.Raw
Membrane module in thing solid-carrying type film biological unit reactor uses inoranic membrane or organic membrane, and conventional membrane material is polypropylene
(PP), polyethylene (PE), polrvinyl chloride (PVC), Kynoar (PVDF), politef (PTFE), polysulfones (PS) etc., film
Aperture is 0.1-0.4um, film external diameter 420～480 μm, thick 40～50 μm of membranous wall, porosity 40～50%, water flux 100～
120L/h/m2(0.15Mpa, 25 DEG C), pH range 1-14.The service life of membrane module is about about 5 years.Through Black Liquor with Efficient Bacteria
Planting the waste water after degraded to enter from hole in membrane module, macromolecular substances and high-efficiency strain in waste water are trapped.Aeration fills
Below hollow fiber film assembly, the shearing force of aeration formation and turbulent fluctuation, make solid be difficult to accumulate in film surface, reduce
The blocking of film and energy consumption.
Above-mentioned biological solid-carrying type film biological unit reactor floor space can save 30%-40%, asks without sludge settling
Topic, resistance to overload shock ability is strong.This technology to the clearance of major pollutants up to COD >=95%, SS > 98%.
Operation case:
Research material: northern area rubber Cu Ji manufacturing enterprise, day waste water generation amount is 400 tons.One phase waste water processes
Technique is " regulating reservoir+hydrolysis acidification+contact-oxidation pool+sedimentation tank ", and water outlet requires to reach integrated wastewater discharge standard (GB
Three grades of discharge standards in 8978-1996), reluctantly can be up to standard.Along with increasing, due to this enterprise's week of around factory and resident
While there is no comprehensive sewage treatment plant, it requires that its sewage water outlet must accomplish integrated wastewater discharge standard (GB 8978-
1996) 1 grade of B standard in.
Its waste water system is transformed by the process system of the application present invention, and biochemical unit utilizes original activated sludge
Pond, makes filler and film unit with the pre-add workpiece of PVC material, and filler uses ceramic polyurethane compounded mix, specific surface area
550m2/m3, proportion 1.05.Film part uses the hollow-fibre membrane of PVDF material, promotees this rubber in spawn culture laboratory needle
After dominant bacteria has been turned out in agent, in the way of adding online in input coefficient, it is ensured that cell body outlet dissolved oxygen > 2mg/L.System
The system domestication debugging time is about 2 weeks, and after normal table runs, concrete Testing index see table shown:
| Project | COD<sub>Cr</sub> | BOD<sub>5</sub> | NH<sub>4</sub><sup>+</sup>-N | SS |
| Former water | 1355 | 280 | 65 | 680 |
| Former Process for Effluent | 490 | - | 30 | 130 |
| Water outlet after transformation | 52 | - | 3 | <10 |
It appeared that fully achieved 1 grade of B requirement of water outlet through improved water outlet, utilize domestication after micro-
Biological this biodegradation character bad waste water being carried out biodegradation, the waste water after biological treatment is through membranous system water outlet,
Rear qualified discharge.Integral device is taken up an area less than 100 square metres, and compact conformation is stable, simple to operate.Integrated treatment becomes
This is less than 10 yuan.
