Description
Technical field
The present invention relates to agricultural fertilizer production fields, and in particular to a kind of processing side of the sewage of marigold extraction lutein
Method.
Background technique
Fresh marigold flower is the raw materials for production for extracting natural carotenol, with both at home and abroad to the continuous of natural carotenol demand
Increase, the plantation of marigold, production and processing scale are also gradually expanded.But the mistake of lutein is extracted in fermentation fresh marigold flower
Cheng Zhong, can give off a large amount of waste liquid, seriously constrain the development of the industry.This waste liquid is in acidity, and ph value is generally in 4.0-
Between 5.5, wherein also containing a large amount of organic substance, ingredient is complex, and direct emission can cause environmental pollution, or even leads
Cause the death of crops.It will be discharged after liquid waste processing according to traditional sewage treatmentmethod, largely having in one side waste liquid
Machine nutrient and minerals nutrient are wasted, on the other hand except the great burden that the expense of water process is also manufacturing enterprise.Cause
This uses a kind of method for being different from conventional process mode now, by organic carbon fertilizer by liquid waste processing at organic carbon nutrient solution.
And in the production process of this nutrient solution, need to send out the various compositions such as waste liquid, decomposer, lye are admixed together
Ferment needs to be passed through during the fermentation parameters, traditional Concentrated fermentations such as oxygen, control temperature and is difficult to control accurately；Marigold
For annual herb plant, lutein rich in is the desirable feedstock for extracting pure natural uranidin.And lutein is a kind of
The natural pigment being widely present in vegetables, flowers, fruit and certain algae bios, it can delay the elderly because of macular degeneration
Caused by vision degeneration and blindness disease, and because body aging cause cardiovascula arteriosclerosis, coronary heart disease and tumor disease, together
When, lutein is not only widely used in feed addictive and food additives field, but also is more and more used for functional guarantor
The upper marigold of research and development and production of health food needs to carry out squeezing processing to marigold, squeezes out it before extracting lutein
In moisture, then carry out the processing of subsequent extraction lutein, and in entire marigold processing, squeezing sewage is maximum and extensively
The pollution sources paid close attention to by environmental protection administration.
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of pollutions avoided to environment, and can make full use of in waste liquid
Utility, simple process, easy-operating longevity chrysanthemum extracts the processing method of the sewage of lutein.
A kind of technical solution: processing method of the sewage of marigold extraction lutein, which is characterized in that including following step
Rapid: 1) the squeezing sewage that marigold extracts lutein is precipitated, and stands 6~10h；
2) after the upper liquid after precipitating is filtered, added in filtrate the anaerobic activated sludge continuous aeration 8 of culture~
10 days；
3) biological bacterium solution and organic carbon bacterium is added；
4) glucose, urea, KH2PO4, MgSO47H2O, CaCl2,42.35mg/L are sequentially added in sewage
NaHCO3 with；
5) fermentation in sewage merging sedimentation basin, sedimentation basin is interior to carry out Anaerobic Treatment
6) filtration treatment of supernatant
Specifically, the anaerobic activated sludge additive amount is the 40~45% of anaerobic activated sludge and filtrate total volume, is added
Enter biological bacterium solution 12% and organic carbon bacterium 3%, and logical amount of carbon dioxide is kept to be maintained at 0.021.5L/L.min.
Specifically, the anaerobic activated sludge culture: first fetch water ditch sewage draining exit sludge or sludge of sewage treatment plant or natural pond
Gas bottom of pond portion activated sludge removes large granular impurity, and filtering is added culture medium, cultivates 42h in 30 DEG C of constant temperature, discards outstanding
Culture medium and KOH is added after liquid again, continues constant temperature incubation 3 days, repeatedly 4~6 times.
Specifically, the culture medium is prepared: according to sludge volume be added 1g/L glucose, 52.75mg/L urea,
The NaHCO3 of CaCl2,42.35mg/L of MgSO47H2O, 20mg/L of KH2PO4,21.5mg/L of 15.5mg/L and
The trace element solution of 1mg/L, upper liquid are precipitated, and 6~12h is stood；Upper liquid after precipitating adds anaerobic activated sludge
It carries out anaerobic fermentation 10~12 days.
Specifically, the anaerobic activated sludge additive amount be anaerobic activated sludge and upper liquid total volume 40~
42.35%, the anaerobic activated sludge is derived from methane-generating pit or biogas project pond body bottom, makes after removing bulky grain sundries
With the collecting methane that anaerobic fermentation generates.
Specifically, the supernatant after the anaerobic fermentation is precipitated, and stands 6~12h, and the sludge circulation participation of deposition is detested
Aerobe fermentation.
Specifically, the supernatant carries out adsorption filtration processing using active carbon and organic carbon at 21.5~35 DEG C of temperature
3~8h.
The invention has the advantages that: extract lutein by precipitating, filtering, anaerobic fermentation, decoloration integrated treatment marigold
Sewage is squeezed, there is at low cost, economical rationality, consumption is small, can substantially reduce the COD that marigold extracts the squeezing sewage of lutein
With purify water, obtaining biogas energy in conjunction with artificial swamp Ecological Disposal finally makes wastewater to reach standard, beautifies the environment, and automates journey
Degree is high, reduces labor intensity.
