The method for processing nitrogen-containing organic waste by using the concentrated sulfuric acid comprises the steps that under the action of the concentrated sulfuric acid, solid or semi-solid nitrogen-containing organic waste is dewatered and carbonized, nitrogen-atoms in the waste react with the concentrated sulfuric acid to generate ammonium bisulfate, and then ammonium sulfate is obtained through performing after-treatment on a product. By using the method provided by the invention, the processing cost of the solid or semi-solid nitrogen-containing organic waste is reduced, and the aims of waste processing and comprehensive utilization are realized.
Description
Technical field
The present invention relates to a kind of method utilizing the nitrogenous organic waste of dense sulfuric acid treatment, belong to organic waste treatment technical field.
Background technology
Along with the high speed development of national economy, the consumption of natural resources and the generation of refuse sharp increase too, cause the exhaustion day by day of some natural resourcess and being on the rise of worldwide environmental pollution thus.Desulfurization refers to solid-state, semi-solid state waste material that pharmaceutical and chemical enterprises produces in activity in production, mainly comprise produce in process of production solid by-product, distillation residue, pollution rubbish etc.
In the production of medicine and fine chemistry industry, a large amount of poisonous and hazardous solid-state, nitrogenous organic waste of semi-solid state can be produced, now basic treatment process be bury, non-thermal plasma trap or burning.These technology all also exist serious harm, bury treatment process, take a large amount of soil, easy leakage pollution soil and water source; Non-thermal plasma trap, running cost is high, and facility investment is large, and processing power is little; The nitrogenous waste of burning method process, although carried out a large amount of improvement, or can produce NO
xwaste gas, needs to increase aftertreatment absorption equipment, increases processing cost.Most of product of medicine and fine chemistry industry all contains nitrogen element, if according to common treatment process, there will be cost high, easily causes secondary pollution problems.
As everyone knows, the vitriol oil has oxidisability and water suction, dehydration property function.Kjeldahl determination experiment just takes full advantage of the characteristic of the vitriol oil, and when natural itrogenous organic substance to be measured and the vitriol oil are total to heat, be oxidized into carbonic acid gas and water, and nitrogen changes ammonification, ammonia is combined with sulfuric acid and generates ammonium sulfate.In order to accelerate the decomposition reaction of organic substance, often add promotor in digestion, copper sulfate can be used as catalyzer, and potassium sulfate or sodium sulfate can improve the boiling point of Digestive system, and oxygenant such as hydrogen peroxide also can accelerated reaction.As can be seen from above principle, to generate carbonic acid gas, not only need under catalyzer (or promotor) exists, and need the boiling point improving Digestive system.
Summary of the invention
The object of this invention is to provide a kind of method utilizing the nitrogenous organic waste of dense sulfuric acid treatment, which reduce solid-state and processing cost that the is nitrogenous organic waste of semi-solid state, reach the object of offal treatment and comprehensive utilization.
The method utilizing the nitrogenous organic waste of dense sulfuric acid treatment of the present invention, under the effect of the vitriol oil, the dehydrated carbonization of the nitrogenous organic waste of solid-state or semi-solid state, the nitrogen-atoms in waste and strong sulfuric acid response, generate monoammonium sulfate, then aftertreatment is carried out to resultant and obtain ammonium sulfate.
The mass concentration of the described vitriol oil is 70 ~ 98%, and compared with solid-state or the nitrogenous organic waste of semi-solid state, the consumption of the vitriol oil is suitably excessive.
The described solid-state or nitrogenous organic waste of semi-solid state is acid amides, oxime, hydrazone, nitrile, amino acid, peptide, protein, alkaloid, aliphatics and aromatic organic amines containing one or more carbonnitrogen bond or carbon oxygen nitrogen key and nitro-compound, diazonium and azo-compound, imidazoles, pyroles, pyrazoles, pyridines, miazines, quinoline or purine compound.
The described reaction times is 2 ~ 10 hours, is preferably 4 ~ 8 hours
Described temperature of reaction is 20 ~ 200 DEG C, is preferably 100 ~ 160 DEG C.
Described aftertreatment is after reaction terminates, and adds reaction mother liquor (first time adds tap water, is all the mother liquor gone out with centrifugation later), stirs, be down to room temperature, use in ammonia and pH to 4 ~ 6 in resultant.
After described neutralization terminates, centrifugation goes out mother liquor, is added in resultant for during aftertreatment again.
The present invention utilizes the oxidation of the vitriol oil and water suction, dehydrating property, by strict Controlling Technology condition, by solid-state or semi-solid state nitrogenous organic waste dehydration carbonization, hydrogen, oxygen element are separated generation water, and generate there is the carbon powder of adsorptivity, nitrogen-atoms and sulfuric acid generate monoammonium sulfate, in ammonia with after, the ammonium sulfate generated is adsorbed onto on carbon powder, as chemical fertilizer.
Gac after organic carbon, there is good adsorptivity, absorption ammonium sulfate and moisture content, reduce the velocity of evaporation of moisture content, can keep, improve and improve the fertility of soil, increase the activity of soil, play the effect of slowly-releasing and soil moisture conservation, promote high grade and yield of crops, reduce agriculture production cost, reach the object improving chemical fertilizer utilization ratio.
The present invention does not add catalyzer (promotor), the temperature that temperature of reaction does not determine nitrogen test is yet high, the boiling point of the vitriol oil is 338 DEG C, Kjeldahl determination experiment needs higher temperature (add potassium sulfate or sodium sulfate, improve the boiling point of Digestive system) can be just carbonic acid gas oxidation of coal.Therefore, our test produces carbonic acid gas hardly, and the carbonic acid gas of the trace of generation is negligible.
The present invention has following beneficial effect:
(1) use common equipment, reduce facility investment;
(2) treatment process is simple, is easy to operate and control, reduces energy consumption, saved processing cost;
(3) waste is converted into fertilizer, and do not have the generation of waste gas, resource obtains Appropriate application.
