Biodiesel Production Line suppliers Biology derv net on May 12 dispatch:
Environmental pollution and energy shortage are the two catastrophe problem that current mankind faces, the scientist of world each district is undertaking hard for this all the time, but obtains research positive result more dispute this namely the individual breakthrough of those, can rise both connection little little. Have a kind of method to you can be in eliminate pollution while production the sources of energy? A few days ago American Lai this a research of the university let us see trifling dawn.
Be magical! Eat to change into sewage an oil
This is published in academic periodical ” ALGAE ” the achievement that go up is based on pair of United States to rest by a definite date of a sewage treatment plant of Si Dui city the research of 5 months. Lai this the scientists of the university discover a kind of mixture algae can be raw material to produce biology fuel with urban foul water.
These high value algae not only survive extremely easily, the nitric acid salt of above of the 90 £¥ in returning waste water of town of can effective purify and the phosphor of 50 £¥ above. According to the data of bureau of American country environmental protection, the nitrogen of the excessive in urban water system and phosphor are “ United States is mixed the most generally one of environmental problems of sex of the richest challenge ” . The technology of useless water treatment with current together with is mixed in salt of purify nitric acid low benefit of phosphor, the import that liquid waste raises alga is more self-evident. And after finishing the job that purifies foul water, these alga still can turn car practicable biology into fuel, satisfy the requirement using oil of traffic carrying trade.
In addition, alga still has a the largest dominant position is, make alcohol fuel differ with traditional corn or candy, it does not contend for the ground with commissariat, do not contend for grain with population. According to American energy department (DOE) 2010 ” route chart of technology of fuel of national alga biology ” , pledge with traditional biology photograph of the sources of energy is compared, every hectare can produce alga more the fuel of 10 times. It is a baby that takes off alive really.
Be pardonable! Be forced but give a bad plan
Algae is treated to make oil before this nevertheless, american is done not have so hopeful.
It is early 5 years ago, alga makes oil is but a inside field of second birth energy popular topic, all sorts of technologies that explore a gender emerge in endlessly. But people discovers finally, it is not actual that through alga mass production gives birth to content fuel, because this need expends too much water, the sources of energy and fertilizer.
Research council of state of subordinate of American country academy of sciences (NRC) report in a research 2012 middle finger goes out: If be below the technical condition at that time, 5% what the biology fuel —— that produces 39 billion litres every year with alga occupies the United States to carry fuel requirement about, requires investment will be very breathtaking: ; In addition, if want to produce 39 billion litres alga biology fuel, cropper still must add the 6 million nitrogen to 15 million tons, and the 1 million phosphor to 2 million tons. This is equivalent to the United States 44% to all nitrogen dosage of 107% , and 20% to the dosage of countrywide agriculture phosphor of 51% . #p#·ÖÒ³±êÌâ#e#
After be being hit to wake by this spank, the centre of gravity of alga industry of the United States changed production to medicaments, nourishment and cosmetic gradually, the domain of these high value, small size. People drops in temperature gradually to the attention of the attribute of its biology fuel.
Paper Lai of the first author this old course learns a Minakeshen · Badachaerji, had studied in what this one domain undertook 28 years continuously. She says, through these year develop, be worth a product as high price, alga industry is solid with each passing day, but depend on chemical fertilizer badly still on production. Look into future, if want manufacturing capacity,more expensive product must be solved above all can develop a problem continuously. From will for a long time look, alga industry is right of chemical fertilizer excessive depending on is not a meddlesome affection to whole industry: Above all this meeting reduces space of industry whole profit; Next, increase long demand with each passing day to chemical fertilizer, the food industry that still can cause alga industry and original one should care his own business forms competition and attrition. Accordingly, liquid waste raises alga is actually by force of helpless choice.
Be original! Temperature is a key dot
Badachaerji says, similar idea is put forward to had had quite long period of time in paper and book, just a few specific detail issues had been not solved, be like whether breed in open environment, use onefold alga or mix breed etc. She says: “ does not know to stem from why to plant reason, the person that has carrying out to this before us is little little, we feel very open-eyed. ”
In new research, badachaerji and her research group got public project of Si Dui city and engineering department are assisted resting. Below the help of this branch, lai this the researcher of the university is in cease the open pool that in handling a works, waste water of Home Si Duiyi built 12 to be used at breeding algae, every cistern can put water about 600 gallon (2.27 stere) . These cistern are used at the filter of the solid in purify sewage to be linked together with sewage treatment plant directly. Different alga bred in every cistern. In having a few pool, mix bred a variety of alga, still include to come from among them cease the alga of Si Dui place. Still raise besides alga in a few cistern have it is the fish that eat with plankton.
The paper is collective author Lai this undergraduate content science teachs dust language · Xi Man says: The research before this has made clear “ , the different combination that to open breed aquatics Yan Zao plants is possible the effect is better. We think amid raises fish to still can eliminate harmful to alga plankton. The result that 5 months come down makes a person special hearten is invigorated, because of the research before this more deflection the onefold breed aquatics at doing not have fish, our research found a kind to let alga produce the method that achieves optimal benefit, best performance. ”#p#·ÖÒ³±êÌâ#e#
In addition, the applicable environment that researcher still raises alga to liquid waste and can effect is evaluated than undertaking. Result discovery, in cease the test that place of Si Dui place has is right the purify effect of the phosphor in liquid waste should compare can Sa this experimental tower above 4 times above. The explanation weighs Badachaerji, this may be the reason of temperature. Cease Si Dui’s test basically is centered in the summer and autumn, temperature wants than Kansan many tall. If temperature is crucial, so cultivate in American southeast and southwest may more economy.
Current, lai this the variable meeting that the group of the university is differring in the test produces what kind of effect to final result, undertake optimizing to this technology accordingly, in order to attract more investor. They hope future can undertake cooperative with more cities, will decide the latent capacity of this kind of alga further. (origin: Small dragon of king of daily of science and technology)
