Background technology
1 ton of furfural of China's furfural industry production consumes 11-12 ton corn cob, discharges 10-11 ton furfural dregs, pH value 2-3, not only contain the elements such as a certain amount of N, P, K, Zn, Mg, Fe, also contain a large amount of organic matters, content can reach more than 90%, and wherein humic acids content reaches 20%.At present, the furfural dregs of domestic most furfural mill is as boiler oil.Take that to produce the furfural of 5000 tons per year be example, the furfural dregs output of 1 year is 60,000 tons, except burning 30,000 tons, still has a large amount of remaining furfural dregs to be difficult to process, and to environment, has caused very large pollution.
Utilize the non-coal resource class xanthohumic acid material of biotechnology exploitation the nineties, be biochemical humic acid Biochemical Humic Acid, be called for short BHA and biochemical fulvic acid Biochemical Fulvic Acid, be called for short BFA in agriculture, herd, the field such as doctor is widely applied.Natural organic resource and waste all can become biochemical humic acid resource, but from utilization of resources value, technology difficulty and the BHA that how to obtain high density, high reactivity, high benefit, analyze, several resources that can develop at present have: agricultural byproducts waste and tankage comprise stalk, waste residue, bran etc.; Fowl and animal excrement and municipal wastes; Commercial fermentation waste thing; Other special resources etc.But yet there are no the report that extracts biochemical humic acid with microbe fermentation method from furfural dregs.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of method unique, reduce environmental pollution, provide a kind of fermentation by microorganism to improve humic acids content in furfural dregs, and utilize furfural dregs after fermenting to produce the method for a kind of producing biochemical humic acid through microbial fermentation of furfural residue of biochemical humic acid.
In order to realize goal of the invention, the present invention realizes in the following way:
The method that microorganism fermentation furfural dregs is produced raw humic acids, is characterized in that: it comprises the steps:
A. in furfural dregs, add waste water at the bottom of the tower of furfural production, furfural dregs water ratio is adjusted to 50%-65%;
B. with urea and wheat bran, regulating the carbon-nitrogen ratio C/N of furfural dregs is 25:1-30:1;
C. bacterium powder is admixed in furfural dregs uniformly, the mass ratio of controlling furfural dregs and bacterium powder is 2000-20000:1, pile in fermentation vat, and fermentation 60-90 days, controlled fermentation temperature is no more than 60 ° of C;
D. to fermentation furfural dregs, add alkali lye, the mass ratio of fermentation furfural dregs and alkali lye is 1:5-1:10, standing at normal temperatures;
E. carry out three grades of sedimentations, first grade subsides 24h, carries out secondary sedimentation to supernatant liquid, after 8h, supernatant liquid is carried out to three grades of sedimentations, obtains the supernatant liquor of clarification;
F. to supernatant liquor, add the hydrochloric acid of 15%-19%, regulate pH to 1.5-2, after humic acids is separated out, filter also by distilled water wash precipitation, then squeeze in spray-drier dryly, drying temperature is 60-70 ° of C, obtains humic acids.
Described alkali lye is that concentration is 1-4%NaOH solution, KOH solution or NH
3h
2o solution;
Described bacterium powder is BM bacterium powder, HM bacterium powder or EM bacterium powder;
At the bottom of described tower, to contain mass concentration be 1.5% acetic acid, the furfural that mass concentration is 0.09% to waste water, and described nitrogen source is urea, ammonium sulfate or monoammonium sulfate, and described carbon source is wheat bran.
The present invention has following effect:
1) method is unique: the present invention be take furfural dregs as raw material, adds waste water at the bottom of the tower in furfural production, and regulating the water ratio of furfural dregs is 50%-65%, and regulating furfural dregs carbon-nitrogen ratio (C/N) is 25:1-30:1.Described nitrogen source is urea, ammonium sulfate, monoammonium sulfate.Described carbon source is wheat bran, and BM bacterium powder, HM bacterium powder, EM bacterium powder are evenly admixed respectively to furfural dregs, and the mass ratio of furfural dregs and bacterium powder is 2000-20000:1, piles in fermentation vat and ferments.Fermentation time 60-90 days, controlled fermentation temperature is no more than 60 ° of C, and the furfural dregs that will ferment immerses in alkaline solution, through Multistage settling, make slag liquid separated, the supernatant liquor obtaining, dry with spray-drier, obtain product biochemical humic acid salt, to the supernatant liquor obtaining, add hydrochloric acid, regulate pH value extremely, after humic acids is separated out, filter and by distilled water wash precipitation, squeeze in spray-drier and be dried, obtain product biochemical humic acid.
2) improved humic acids content: method furfural dregs provided by the invention is after microorganism fermentation, and humic acids content is increased to 50% by 20%, has improved 150%.
