Abstract
The invention provides a method for culturing microalgae by using alcohol wastewater and fermentation exhaust, which comprises the steps of anaerobic digestion of alcohol wastewater, microalgae culture, wastewater recovered mixture for alcohol fermentation, and the like. The method specifically comprises the following steps: carrying out anaerobic digestion on the alcohol wastewater; culturing the microalgae by using the liquid obtained by solid-liquid separation to obtain a microalgae thallus product or extracted biological grease, wherein fermentation exhaust is introduced to supplement the carbon source required by microalgae growth in the process; and recovering the microalgae purification liquid to the alcohol production mixture technique. The method for culturing microalgae by using the alcohol anaerobic wastewater and fermentation exhaust can eliminate the inhibiting action of ammonia nitrogen on alcohol fermentation, enhances the feasibility of alcohol fermentation by recovering treated wastewater, implements the zero discharge of the wastewater and fermentation exhaust in the alcohol production process, solves the key technical bottle neck for restricting the clean production of alcohol fermentation, and obtains the high-value microalgae thallus product or biological grease.
Description
Technical field
The invention belongs to bioengineering field, be specifically related to a kind of method utilizing alcohol waste water and fermentation tail gas to cultivate micro-algae.
Background technology
At present, traditional alcoholic fermentation process produces containing CO
2tail gas, not by rational and efficient use, be all discharged in air and become greenhouse gases, the rate of recovery of carbon is lower, is unfavorable for the alleviation of Greenhouse effect, has special bad smell to produce in fermentation tail gas, have a strong impact on the orthobiosis of surrounding resident, therefore, must administer fermentation tail gas.And traditional alcohol waste water process adopts " secondary anaerobic+aerobic " art breading usually, waste water after anaerobism contains the materials such as a large amount of organic acids, microbial cells, ammonia nitrogen and phosphorus and is inhibition in alcoholic fermentation process, hinder waste water direct reuse to alcoholic fermentation process, need to deliver to Aerobic Pond and carry out aeration manipulation, more just can qualified discharge by chemical agent advanced treatment by the waste water after aerobic treatment.Because alcohol waste water amount is comparatively large, particularly the aerobic aeration stage needs to consume a large amount of energy this technological process, adds the cost of Alcohol Production to a certain extent.
Micro-algae be a class on land, ocean is widely distributed, the holophyte that nutritious, photosynthetic availability is high, the polysaccharide that cellular metabolism produces, protein, grease and pigment etc., make it have good DEVELOPMENT PROSPECT in fields such as food, medicine, genetically engineered, liquid fuels.
Nitrogenous source in the tail gas that micro-algae can utilize zymamsis to produce and alcohol waste water, phosphorus source grow, the organism such as synthesis polysaccharide, protein, grease and pigment, thus denitrogenation dephosphorizing can be carried out to natural pond liquid, realize nutrient to reclaim and recycling, reach the waste water in alcohol production process and fermentation waste gas zero release, solve the gordian technique bottleneck that restriction zymamsis realizes cleaner production.
Summary of the invention
The object of the invention is to provide a kind of method utilizing alcohol waste water and fermentation tail gas to cultivate micro-algae, this technology utilization alcohol waste water fermentation and fermentation tail gas cultivate micro-algae can eliminate the restraining effect of ammonia nitrogen to zymamsis, improve the feasibility of processed waste water reuse zymamsis, achieve the waste water in alcohol production process and fermentation waste gas zero release, solve the gordian technique bottleneck that restriction zymamsis realizes cleaner production, and obtain micro-phycomycete body product or the bio-oil of high value.
For achieving the above object, the present invention adopts following technical scheme:
A kind of method utilizing alcohol waste water and fermentation tail gas to cultivate micro-algae, the method technique mainly comprises alcohol waste water anaerobic digestion, microdisk electrode (passing into fermentation tail gas in process), filtering separation micro-phycomycete body product or extraction bio-oil, the waste water recycling spice be purified is for processes such as zymamsiss.
In concrete implementation process, a bio-reactor can be increased after anaerobic digestion process, the waste water after two-stage anaerobic digestion is passed in bio-reactor; Inoculate a certain amount of micro-algae, pass into containing CO in process
2fermentation tail gas supplementary carbon source, after micro-algae cultivates 5 ~ 20 days in bio-reactor, in waste water, total ammonia nitrogen and phosphorus are effectively degraded; Waste water containing micro-algae pumps into has been filter device, and micro-algae is filtered and is separated, and the waste water recycling be purified is in the spice technique of zymamsis raw material.
Accompanying drawing explanation
Fig. 1 is a kind of method technical process utilizing alcohol waste water and fermentation tail gas to cultivate micro-algae.
Embodiment
The inventive method is described in further detail for raw material carries out microdisk electrode for certain factory's anaerobic digestion alcohol waste water below, but protection scope of the present invention is not limited thereto.
Embodiment
(total ammonia nitrogen content is 911.5mg/L to get certain factory's two-stage anaerobic digestion alcohol waste water, total phosphorous is 88.3mg/L) 300L adds in bio-reactor, the microalgae cell of inoculation 5%, after 20 days when microalgae cell breeding is vigorous, total ammonia nitrogen in wastewater measurement and total phosphorus are respectively 10.3mg/L and 0.35mg/L, reach reuse standard.Filtering separation micro-phycomycete body product 3000g(dry weight), wherein bio-oil content is 40%.The reuse water of purification directly joins in the spice technique of zymamsis, and in last fermented liquid, ethanol concn is suitable with control group (non-reuse water).
