Description
Technical field
The present invention relates to composite and field of waste water treatment, and in particular to a kind of visible light-responded photocatalysis-micro- life
Thing composite and preparation method and application.
Background technology
Dyeing waste water is one of major polluting sources in China's industrial system, is counted according to State Environmental Protection Administration, dyeing row
The dyeing waste water total amount put is located at total flow control five of national each industrial department discharge, and its gross contamination emission is (with COD
Meter) then it is located at each Ministry of Industry's family status six.Dyeing waste water water quality colourity is high, low thousand of times, high hundreds of thousands times；COD and BOD
Concentration is high；Complicated component, except containing nitro, amino, hydroxyl, halogen, alkyl also have aromatic hydrocarbon that the mixing of above-mentioned group replaces,
Heteroaromatic hydrocarbon, polycyclic aromatic hydrocarbon, heteroaromatic hydrocarbon, aliphatic hydrocarbon, unsaturated fatty acidss hydrocarbon compound etc., toxicity is big.Dyeing waste water
Discharge huge impact is generated to aquatic ecosystem and its boundary environment, its poison event exposed day by day.Therefore print and dye
The process of waste water is the focus of current research.
The process of dyeing waste water includes Physical, chemical method and bioanalysises.Wherein biological treatment is most widely used at present
, but in view of biological treatment efficiency is low, and with the generation of the higher intermediate product of toxic, the photochemical catalytic oxidation in chemical method
Arise at the historic moment.Photocatalysis oxidation technique can produce the very strong free radical of oxidisability, can rapid damage pollutant molecular structure, but
It is that photocatalysis technology is adapted to low concentration waste water from dyestuff, and its oxidation is that hardly possible controls its response time without selectively.So needing
Photocatalysis to be studied-microorganism composite, reach the purpose for processing dyeing waste water by the advantage with reference to two kinds of technologies.
The content of the invention
The technical problem to be solved is：For the problem that prior art is present, the present invention provides one kind can
The composite of photocatalysiss and biodegradability is played simultaneously, is given up with biological synergetic degradation of dye to obtaining photocatalysis
Water, makes up independent photocatalysis and independent biodegradation processes the shortcoming of waste water from dyestuff；And the composite degradation efficiency high, price
Cheaply, it is easy to separate and recover.
To solve above-mentioned technical problem, the present invention is employed the following technical solutions：
A kind of visible light-responded photocatalysis-microorganism composite, which includes photosynthetic bacteria and g-C3N4-P25Photocatalyst；
Photosynthetic bacteria and photocatalyst are distributed in calcium alginate carrier, the composite be in microspheroidal, its a diameter of 2-3mm.
Wherein, described g-C3N4-P25Composite photo-catalyst, its g-C3N4With P25Mass ratio be 1.5:1.
Described g-C3N4-P25Photocatalyst, alternatively g-C3N4, the visible light-responded photocatalysis such as modifying titanium dioxide
Agent.
The photosynthetic bacteria is in corynebacterium, is rhodospirillum, with high COD degradation ability.
Another object of the present invention is to provide it is a kind of prepare visible light-responded photocatalysis as claimed in claim 1-
The method of microorganism composite, comprises the following steps：
1）Take g-C3N4-P25During photocatalyst adds sodium alginate soln, the mass ratio of described photocatalyst and sodium alginate
For 0.5-2:1, described sodium alginate concentration is 1-4%w/v, and ultrasound makes which be uniformly dispersed；
2）Photosynthetic bacteria bacteria suspension is added obtained in step 1 in mixed solution, described photosynthetic bacteria bacteria suspension and alginic acid
The mass ratio of sodium is 1-3:1, solution stirring is uniform；
3）Photocatalyst obtained in step 2 and bacterium mixed liquor are instilled into 1-4%w/v CaCl with syringe2In solution, 4 DEG C are placed
After lower hardening 24 hours, with standby after distilled water wash.
A kind of application using dyestuff and COD in above-mentioned visible light-responded photocatalysis-microorganism composite degradation water,
Comprise the following steps：
A certain amount of photocatalysis-microorganism composite is added in containing dyestuff and high concentration COD solution, wastewater pH is adjusted
=5-9, irradiates under visible light, stewing process.
In above-mentioned composite, the described visible light-responded photocatalyst being distributed in carrier, wherein rising leading
The photocatalyst for being distributed across calcium alginate carrier surface of effect, and the photocatalyst of carrier inside is located at due to being subject to
The irradiation of light, is nearly free from electron-hole pair.But it be stressed that the addition of nanometer materials can increase calcium alginate carrier
Mechanical strength, so, be also effective positioned at the photocatalyst of carrier inside.
Compared with prior art, it is an advantage of the current invention that:
1st, photocatalysis-microorganism composite of the invention solves the difficult point that integrated photo-catalytic is coupled with microorganism.
2nd, photocatalysis-microorganism composite of the invention, by calcium alginate carrier by photosynthetic bacteria and photocatalyst
It is fixed in same system, the generation free radical under the exciting of light of the photocatalyst outside carrier, the difficulty that can be destroyed in waste water
With biodegradable molecular structure；And the microorganism inside carrier is embedded in as the protective effect of carrier can be from free radical
Attack so that the composite has photochemical catalytic oxidation and biodegradability simultaneously.That is removal of the photocatalytic method to colourity is imitated
Rate and biological oxidation process to emerging from the present invention the advantages of the degraded of COD in solution, integrated photo-catalytic method and life
The coupling of thing method can play a part of mutual supplement with each other's advantages, and waste water treatment efficiency is much larger than photocatalytic method and bioanalysises.Additionally, nanometer
The addition of level photocatalyst can strengthen the mechanical strength of calcium alginate microsphere.The fixation of calcium alginate also solves photocatalyst
The step of difficulty is centrifuged with photosynthetic bacteria in actual applications.
3rd, by g-C3N4With P25It is compound, can be by P25Light absorbs expand visible region to, and photocatalytic activity is all
More than P25And g-C3N4Photocatalytic activity.This is just more beneficial for photocatalysis-microorganism composite and is generalized in practical application.
4th, the preparation method of composite of the invention, can be prepared by by simple technique while having photocatalysis and life
The composite of thing degraded.Because combining both advantages, the composite treatment effeciency is high.
