Abstract
The invention discloses a method for preparing amino-fulvic acid by oxidizing excrement, which comprises the steps of introducing nitric acid serving as an oxidant into livestock excrement in a reaction kettle, stirring and mixing the excrement introduced with the oxidant, heating, maintaining for a certain time, carrying out solid-liquid separation on the oxidized excrement by using a centrifugal machine, extracting AFA stock solution containing organic acid substances, and decomposing the organic acid from the solution. The process is simple, no waste is discharged, and the environment is not polluted.
Description
Technical field
The present invention relates to a kind of oxidation ight soil and make the method for amino-xanthohumic acid; Be applicable to the feces of livestock and poultry to be the method that amino-xanthohumic acid is made in the quick oxidation deodorizing of raw material.
Background technology
The feces of livestock and poultry treatment technology mainly contains both at home and abroad at present:
Biogas fermentation: its technology mainly is anaerobically fermenting, produces methane and makes fuel, and biogas can be used for field irrigation, and the natural pond slag is made fertilizer.But at scale raising, most biogas engineering investments are big, and operational efficiency is low.Present natural pond liquid, the condition of natural pond slag making commercial fertilizer is immature, and natural pond liquid, natural pond slag can't be dissolved, and become secondary pollution.
Hyperthermia drying: technology is that feces of livestock and poultry is directly dried through 700 ℃～900 ℃ high temperature, forms fertilizer.Problem: 1. handle feces of livestock and poultry with drying technology and cause the air severe contamination; 2. fertilizer is made in the feces of livestock and poultry oven dry, owing to do not become thoroughly decomposed, uses the field at certain temperature and humidity conditions bottom fermentation, and the improper use meeting causes crop failure to be put into obsolete product.
During High-Temperature Composting: technology is in fixed ventilating fermentation pond, regularly uses mechanical stirring, and fully fertilizer is made in fermentation.Shortcoming: pilling up time is longer, needs 20d-30d, and floor space is bigger, and simultaneously, the liquid dung that this method produces also can't harmless treatment.
Tower fermentation: feces of livestock and poultry inoculation bacteria agent is current a kind of forward position treatment technology, and this technology is introduced the multilayer fermentation tower with ight soil, oxygenation, stirs fermentation automatically, produces active organic fertilizer.Problem is can't solve the liquid dung innocuity treatment problem equally, and simultaneously, being used for fermentation tower is metal construction, and work-ing life is short.Therefore, facility investment height.
Summary of the invention
The invention provides a kind of quick oxidation deodorizing feces of livestock and poultry and make the method for amino-xanthohumic acid.
In order to solve above technical problem, a kind of oxidation ight soil of the present invention is made the method for amino-xanthohumic acid, and described production method is as follows: a, feces of livestock and poultry is introduced reactor; B, introducing nitric acid as oxidant, 100 parts of feces of livestock and poultry are introduced 4 parts-14 parts in nitric acid; C, the ight soil of introducing oxygenant is mixed post-heating, maintain the regular hour again; D, carry out solid-liquid separation with the ight soil of whizzer after to oxidation, liquid is the AFA that contains glucide and organic acidic material, and solid is the excrement slag; E, extraction AFA stoste decomposite organic acid from solution.
The concentration mass ratio of described ight soil and nitric acid is 40%-98%:60%-2%.
The temperature of heating in the described C step is: 85 ℃-105 ℃.
Service time is in the described C step: 3-5 hour.
Described organic acid is amino acid, xanthohumic acid.
The advantage of above technology is:
1, feces of livestock and poultry of the present invention need not to carry out pre-treatment, in the various treatment technologies of feces of livestock and poultry, except that biogas fermentation, hyperthermia drying, all need carry out pre-treatment at present, be adjusted to moisture about 65%.
2, feces of livestock and poultry was degraded under whole sealing status and was carried out non-exhaust emission; Current domestic and international feces of livestock and poultry is handled and mostly is greatly that standard-sized sheet is put or open, and technological process all has discarded discharging, contaminate environment.
3, AFA of the present invention is that stoste is major product, and filter residue is a byproduct as fertilizer; AFA is that stoste and AFA filter residue are as fertilizer synergistic agent, combine with chemical fertilizer, make high nitrogen or composite fluid fertilizer, increase substantially fertilizer efficiency and chemical fertilizer utilization ratio, be feces of livestock and poultry treatment technology (except the hyperthermia drying), all have the liquid dung harmless treatment, cause secondary pollution, restriction technology popularization is used.The feces of livestock and poultry of handling is all made fertilizer and is used.
4, in the total solvable organic matter of AFA stoste, carbohydrate accounts for 18.15%, and wherein five-carbon sugar accounts for carbohydrate 9.46%, and hexose accounts for 5.12%; Total organic acids accounts for 81.85%, and wherein amino acid accounts for 10.16%, and xanthohumic acid accounts for 30.61%.The gross activity acidic-group is 11.16mmol/g, the peat acidic groups that is higher than Zhanjiang, Guangdong, Kunming, Yunnan, the weathered coal acidic groups that also is higher than Turfan, Xinjiang, Gongyi, Henan is lower than the organic acidic groups of Canadian soil, more than is the theoretical foundation that the present invention makes fertilizer synergistic agent.Current feces of livestock and poultry treatment technology does not appear in the newspapers to above-mentioned proportion of composing of product and activity.
5, equipment is succinct, and is corrosion-resistant, and power consumption is few, less investment.The technological process major equipment is reactor and whizzer, but enamel reaction still as long as in use do not collide just life-time service, the acid and alkali-resistance whizzer usage period is also longer; Connect the tower body of the tower fermentation of bacterial classification, investment is big, and the life-span is short, generally has only about 2 years.
6, time weak point, degradation process 4h～8h, no stink; General biological fermentation, for up to 20d～30d, tower fermentation is the shortest, also needs 5d～6d.
Embodiment
Feces of livestock and poultry is introduced reactor, the amount introducing nitric acid of joining 4 parts to 14 parts in nitric acid again with 100 parts of feces of livestock and poultry, being heated with stirring to temperature then is 95 ℃ ± 10 ℃, keep after 4 hours the ight soil after the oxidation being led into whizzer, carry out solid-liquid separation with whizzer, separating back liquid is AFA, solid is the excrement slag, and liquid level AFA extracts, and solid excrement slag is derived and made organic fertilizer; Analyze for the AFA stoste of extracting, contain amino acid, xanthohumic acid, carbohydrate and water in the stoste.In this mixture, add urea and make high nitrogen fertilizer, replace urea to use, or add n p k fertilizer, make foliage fertilizer or composite fertilizer, replace the fertile use of compound.The AFA filter residue adds nitrogen, phosphorus, potassium fertilizer and makes the AFA compound organic and inorganic fertilizer.Dash fertilising if do, can keep moisture.
