Abstract
The present invention provides a kind of method and apparatus for handling waste water and producing nutriment, the method includes the steps: 1) concentration of waste water is adjusted, until wherein COD is 6000-8000mg/L；The carbon N/P ratio in nitrogen source and phosphorus source adjusting waste water is added；2) photosynthetic bacteria of the inoculation in logarithmic growth phase is in waste water；3) it is exciting light Continuous irradiation graphene quantum dot solution with the ultraviolet light that wavelength is 365nm, irradiates waste water with the graphene quantum dot solution of flowing；4) plateau is reached to photosynthetic bacterium growth, carries out the separation of bacterium water using filter membrane.The invention proposes a kind of sewage recyclings for producing high value photosynthetic bacteria to utilize method; it is the method for the wastewater treatment and recycling that combine brewery wastewater treatment with output high value nutrients; both the removing of Pollutants in Wastewater may be implemented; the biomass of generation can extract high value nutrients again, play environmental protection, save the cost, Resource recovery multi-efficiency.
Description
Technical field
The invention belongs to waste water reclaiming technical fields, and in particular to a kind of to handle the method for waste water using quantum dot and set
It is standby.
Background technique
The waste water of food service industry production discharge is mostly that high concentration is organic, nontoxic waste water, but is easy to corruption, is made to water body environment
At harm.The techniques such as common SBR, CASS, UASB are handled at present, and long flow path generates a large amount of excess sludges, and can not have
Effect ground recycles benefit materials therein.Pollutant can be effectively treated using photosynthetic bacteria brewery wastewater treatment, and can
To convert thallus for utility therein, high value nutrients is recycled.Photosynthetic bacteria is that one kind is widely distributed, collects current generation
The microorganism that all metabolic ways (including illumination autotrophy, illumination heterotrophism, chemautotrophy, chemoheterotrophy) are integrated in boundary；It is given birth to
Long speed is fast, growth cycle is short, while wide to organic matter utilization scope, removal pollutant it is high-efficient be used for the treatment of very early it is useless
Water.In addition, thallus is non-toxic, rich in several physiological active substances such as protein, pigment, vitamins, it is widely used in water
Are produced from the fields such as feed addictive, Crop fertilizer, melon and fruit antistaling agent, health care product, medicament, there are great recycling potentiality.Mesh
Before, photosynthetic bacteria culture mostly uses illumination anaerobism mode, and light source is the uniform incandescent lamp of spectrum.But incandescent light source cannot protect
It holds steadily in the long term, decaying is very fast, and incandescent lamp efficiency is low, and service life is short, and power consumption is big.
Quantum dot is the semi-conductor nano particles that can produce luminescence generated by light phenomenon of the diameter between 1-100nm, graphite
Alkene be one kind by carbon atom with sp2The honeycomb flat film that hybrid form is formed.Graphene quantum dot has graphene simultaneously
And the characteristics of quantum dot, show stronger quantum confined effect and boundary effect.Meanwhile graphene quantum dot also show it is low
Cytotoxicity, good water-soluble and biocompatibility, chemical inertness, stable photoluminescence performance so that it becomes amount
The focus of son point field of nanometer material technology.Based on graphene quantum dot photoluminescence property, pointedly provided more for photosynthetic bacteria
Stablize, more uniform light source, is a technology of base friend's prospect.
Summary of the invention
For shortcoming existing for the art, the purpose of the present invention is to propose to a kind of using at graphene quantum dot
Reason waste water and the method for producing nutriment.
Second object of the present invention proposes that a kind of handle using graphene quantum dot and produces nutriment at waste water
Equipment.
Quantum dot graphene has the characteristics that emission wavelength is controllable, it is energy saving to be used for a long time, and present inventor is also
It was found that quantum dot graphene is better than incandescent light to the growth result of photosynthetic bacteria.It is touched by the optimization to various experimental conditions
Rope proposes technical solution of the present invention.
Specifically, above-mentioned purpose technical solution of the present invention is realized are as follows:
A method of waste water being handled using graphene quantum dot, comprising steps of
1) concentration of waste water is adjusted, until wherein COD is 6000-8000mg/L；Nitrogen source is added and phosphorus source is adjusted in waste water
Carbon N/P ratio；The waste water is one of beer waste water, soybean processing waste water, molasses containing waste water or a variety of；
2) it is photosynthetic bacteria of the 200-500mg/L dry weight inoculation in logarithmic growth phase in waste water with inoculum concentration, adjusts
PH value is to 6.8-7.0；
It 3) is graphene quantum dot solution that exciting light Continuous irradiation partial size is 1-2nm with the ultraviolet light that wavelength is 365nm,
Graphene quantum dot therein is set to absorb energy, electronics returns ground state from high energy order transition and issues the fluorescence that wavelength is 550-620nm
Light source as photosynthetic bacterium growth；The waste water of photosynthetic bacteria is vaccinated with the graphene quantum dot solution irradiation of flowing；
4) to photosynthetic bacterium growth reach plateau, using filter membrane carry out the separation of bacterium water, obtain photosynthetic bacteria concentrate and
The photosynthetic bacteria concentrate is used to extract carotenoid, bacteriochlorin by membrane filtration clear water.
This technology is based on graphene quantum dot photoluminescence property, pointedly provides for photosynthetic bacteria more stable, more equal
One light in 550-620nm promotes the synthesis of photosynthetic pigments in photosynthetic bacteria, improves photosynthetic efficiency, can both do
To the recycling of Pollutants in Wastewater, the biomass of generation can extract pigment again, realize the processing and recycling of sewage
It utilizes.
Preferably, in step 1), the nitrogen source is NH4Cl、(NH4)2SO4、NH4NO3One of or a variety of, phosphorus source
