Description
Engineering field
The present invention relates to the field of chemical industry and agriculture, and in particular to a method for producing reagents for cleaning (detoxication, disinfection and decontamination) contaminated areas, for example, for purifying municipal treatment plant sewage sludge, various chemicals, food and livestock facilities (animal manure and bird droppings), including surrounding areas affected by radioactive contamination.
Technical level
The state of the art refers to the production method of amino acid toxic agents disclosed in EN 2457909 C1 published 8/10 2012. According to the above sources, an amino acid detoxification reagent containing copper, zinc, lead, chromium, cobalt, nickel and cadmium ions is prepared by mixing a protein-containing material with water in a ratio of 10% of a reagent detoxification agent and 90% of water.
The disadvantage of the above-described solution is the low sewage sludge treatment level and limited application range, since the two stages use different reagents and increase the treatment time.
Furthermore, the state of the art describes a composition for sewage sludge decontamination and a method for its production (RU 2332361C1, published 8/10 2012, prototype). The sewage sludge treatment formula comprises the following components in percentage by mass: hydrates of sodium or potassium salts of amino acid mixtures-4-8; copper or zinc hydrate complexes of amino acid mixtures-15-20; dipeptide, tripeptide and tetrapeptide sodium salts-2-5; alkali-3-4; the balance being water. The composition is prepared by mixing the above components obtained in advance. Further, the hydrate of the sodium salt or potassium salt of the amino acid mixture was prepared by heating on steam at a temperature of 170 ℃ and treating the mixture at this temperature in a circulation mode containing sodium hydroxide or potassium hydroxide, protein containing waste and water for 40 minutes, then stopping the steam supply, adding 200mL volume of water after the mixture circulation was completed, and mixing again for 15 minutes. Copper hydrate complexes of the amino acid mixtures were prepared by mixing 25% aqueous ammonia solution and 2M copper sulfate solution (added at a temperature of no more than 35-45 ℃) and continuing mixing for 3-5 minutes. An aqueous solution of sodium or potassium hydrate of the amino acid mixture and an additional amount of sodium or potassium hydroxide are added to the mixture.
The disadvantage of the above technical solution is the use of superheated steam, which results in high energy costs and additional safety measures for the staff when using the equipment. Thus, in the issued patent, the hydrolysis is incomplete and peptide residues remain in the hydrolysis product.
Disclosure of the invention
The object of the claimed invention is to develop a reagent which is capable of decontaminating contaminated facilities in a highly purified manner.
The invention has the technical effect of improving the cleaning degree of the polluted device.
The technical effect is achieved by the following facts: reagents for purifying waste water from municipal construction, chemistry and food facilities include sodium or potassium salts of amino acids-mixtures of sodium or potassium salts of 20 standard amino acids, generally reactive materials (surfactants) -mixtures of sodium or potassium salts of fatty acids of the formula C nH2n+1 COONa or C nH2n+1 COOK (where n=4-18), polysaccharide hydrolysates, hydroxyaminocopper complexes, copper-ammonium amino acid complexes-copper-ammonium amino acid complexes on the basis of 20 standard amino acids, having the following composition ratios in mass%:

The rest is water.
The technical effect is also achieved in that the wastewater treatment method of municipal construction, chemistry and food facilities comprises the following stages:
-preparing a feedstock-biowaste material containing a mixture of proteins, fats and carbohydrates;
-hydrolyzing the feedstock in the presence of NaOH or KOH to produce a hydrolysate which is a mixture of sodium or potassium salts of 20 standard amino acids, surfactant-sodium or potassium salts of fatty acids of formula C nH2n+1 COONa or C nH2n+1 COOK (where n=4-18) and polysaccharide hydrolysate;
-cooling the hydrolysate to 40 ℃, followed by adding collagenase, protease, lipase to the mixture;
-producing a finished product containing the hydrolysate, copper hydroxy amino acid complex, copper ammonium amino acid complex by adding copper (II) sulphate and an aqueous ammonia solution to the hydrolysate.
Implementation of the invention
Mixtures of sodium or potassium salts of 20 standard amino acids, mixtures of sodium or potassium salts of surfactant-fatty acids (C nH2n+1 COONa or C nH2n+1 COOK, where n=4-18), polysaccharide hydrolysates, copper hydroxy amino acid complexes and copper-ammonium amino acid complexes-mixtures based on 20 hydroxy amino acids and amino-amino acid complexes-correspondingly having the following composition ratios in mass%: 5-15 parts of amino acid sodium salt or potassium salt; fatty acid sodium salt or potassium salt-5-10; copper hydroxy amino acid complex-5-10; copper-ammonium-amino acid complex-5-10; polysaccharide hydrolysate-1-5; the remainder is water, i.e. the following is carried out to obtain the claimed reagent for cleaning contaminated facilities, which contains sodium or potassium salts of amino acids.
The first stage shows the initial raw material preparation-biowaste containing a mixture of protein (B), fat (L) and carbohydrate (Y), the composition ratios (mass%) of which are as follows: b-85-94; f-5-10, Y-1-5; the balance being water. The preparation of the raw materials comprises water washing to remove solid particles (sand, soil and the like) and aggregate separation. Animal blood, non-reusable viscera, hair, down, feathers, bones, horns, hooves, seafood, fish scales, skin epidermis, connective tissue, debris (limbs), unconditioned meat, poultry, fish, shell, meat products, shellfish, milk, farmed cheese, yogurt, eggs, and carcasses of animals, birds, dead fish, and other marine organisms can all be examples of biological waste.
The biowaste is charged into a reactor equipped with a homogenizing pump and a frame stirrer, and then a certain amount of NaOH or KOH (11.15-10.22 mmol, per 1kg dry weight of protein) and water are added. The mixture containing the biowaste was stirred by a frame stirrer and heated to 100 ℃. The homogenizing pump is then turned on. The hydrolysis process took 1 hour. Then, collagenase, protease and lipase were added to the mixture after cooling the mixture to 40 ℃. Proteases and collagenases catalyze peptide bonds in proteins and polypeptides that remain after alkaline hydrolysis. The lipase breaks down the triglycerides remaining after the alkaline hydrolysis reaction into fatty acids. The mixture was stirred with a frame stirrer for a further 2 hours at a temperature of 40 ℃. The result of the hydrolysis is a hydrolysate containing the following components in mass-%:
1. Protein hydrolysate (85-94% by mass in the hydrolysate mixture) -sodium or potassium salt of an amino acid, which is a mixture of sodium salts of 20 standard amino acids, i.e. a mixture consisting of various salts, wherein the cation is sodium and the anion is various amino acids selected from 20 standard amino acids, i.e. a mixture of salts: alanine sodium or potassium salt, valine sodium or potassium salt, leucine sodium or potassium salt, isoleucine sodium or potassium salt, proline sodium or potassium salt, glycine sodium or potassium salt, serine sodium or potassium salt, threonine sodium or potassium salt, cysteine sodium or potassium salt, tyrosine sodium or potassium salt, tryptophan sodium or potassium salt, asparagine sodium or potassium salt, glutamic acid sodium or potassium salt, histidine sodium or potassium salt, asparagine sodium or potassium salt, phenylalanine sodium or potassium salt, arginine sodium or potassium salt, lysine sodium or potassium salt, methionine sodium or potassium salt, glutamine sodium or potassium salt. The ratio of the 20 standard amino acid sodium salt mixture is consistent with the ratio of 20 standard amino acids in the protein.
2. Fatty acid hydrolysate (5-10% by mass in hydrolysate mixture) -surfactant consisting of a mixture of sodium or potassium fatty acids with a carbon content of 4-18, i.e. a mixture consisting of various salts, wherein the cation is sodium or potassium and the anion is a fatty acid residue with a carbon content of 4-18, i.e. a mixture of salts: c 4H9 COONa or C 4H9COOK、C5H11 COONa or C 5H11COOK、C6H13 COONa or C 6H13COOK、C7H15 COONa or C 7H15COOK、C8H17 COONa or C 8H17COOK、C9H19 COONa, C 9H19COOK、C10H21 COONa, C 10H21COOK、С11Η23 or C 11Η23СΟΟK、С12Η25 or C C 12Η25СΟΟK、С13Η27 C, O Na or C 13Η27СΟΟK、С14Η29 C, O Na or C 14Η29СΟΟK、С15Η31 C, O Na or C 15Η31СΟΟK、С16Η33 C. O Na or C 16Η33СΟΟK、С17Η35 C O Na or C 17Η35СΟΟK、С18Η37 O Na or C 18Η37 O K.
3. Carbohydrate hydrolysate (1-5% by mass of the hydrolysis mixture) -hydrolysate of polysaccharide (cellulose, chitin, starch and glycogen mixture) -hydrolysate of cellulose mixture, chitin, starch and glycogen. The proportion of the components in the hydrolysate is consistent with the proportion of the components in the polysaccharide.
The resulting hydrolysate was then cooled to 25℃and 20-62% CuSO 4 (10-25% aqueous CuSO 4) and 6-20% NH 4 OH (5-30% aqueous ammonia) were added to the total hydrolysate. Stirring was continued for 20 minutes to give a dark blue and homogeneous mixture, as a result of which interaction with the sodium salts of the 20 standard amino acids was effected by adding CuSO 4 and NH 4 OH to the hydrolysate to form copper oxide-ammonium-amino acid complex and copper hydroxy amino acid complex. Copper-ammonium-amino acid complexes are mixtures of various combinations of the formula [ Cu (NH 3)3A]SO4, where a is an amino acid residue selected from 20 standard amino acids), a mixture of sodium or potassium salts having a portion (2-8 mass%) of 20 standard amino acids will not react to form a complex because the amount of CuSO 4 and NH 4 OH injected is insufficient for all of the quantitative amino acids in the hydrolysate to react properly to form a complex. The result is a product (dark blue liquid. PH 8-12; density 1.0-1.35g/cm 3) -a reagent as claimed for cleaning contaminated facilities, containing sodium or potassium salts of amino acids-sodium or potassium salt mixtures of 20 standard amino acids, SAS mixtures of sodium or potassium salts of fatty acids of the formula C nH2n+1 COONa or C nH2n+1 COOK (where n=4-18), polysaccharide hydrolysates, copper hydroxyamino acid complexes and copper ammonium amino acid complexes being mixtures of hydroxyamino acids and copper amino acid complexes based on copper of 20 standard amino acids, respectively, the mass% of the ingredients being as follows: sodium or potassium salts of amino acids-5-15; sodium or potassium salts of fatty acids-5-10; 5-10 parts of copper hydroxy amino acid complex; copper-ammonium-amino acid complex-5-10; polysaccharide hydrolysate-1-5; water-the remainder.
The required reagents include: the sodium or potassium salt of an amino acid acts as a surfactant; the polysaccharide hydrolysate acts as a flocculant; the copper-ammonium-amino acid complex acts as a disinfectant; the sodium or potassium salts of amino acids are required to form complexes in sewage sludge to inactivate heavy metals, and copper hydroxy amino acid complexes act as disinfectants. The fatty acid salt has active surface activity and accelerates the infiltration of the formula to the purification of the building. The polysaccharide hydrolysate has the characteristic of forming complex, and can improve the detoxification efficiency of heavy metals.
The copper-ammonium amino acid complex is a combination of different complexes of the formula [ Cu (NH 3)3A]SO4, wherein A is an amino acid selected from 20 standard amino acids, i.e. a mixture of 20 complexes selected from 20 standard amino acids, each of which has a different amino acid residue.

The result is the claimed reagent for cleaning contaminated facilities comprising a mixture of potassium amino acid salts-20 standard potassium amino acid salts, a surfactant-a mixture of potassium fatty acid salts having the structure C nH2n+1 COOK (where n=4-18), a polysaccharide hydrolysate and a copper-ammonium amino acid complex-a combination of copper-ammonium amino acid complexes based on 20 standard amino acids, having the following composition ratios, mass%: amino acid potassium salt-5; fatty acid potassium salt-5; copper hydroxy amino complex-5; copper-ammonium-amino acid complex-5; polysaccharide hydrolysate-5; water-the remainder.
Example 11
The starting material for this biowaste was 100kg of animal deer horn, with the following parameters of PFC in mass%: protein-89; fat-5; carbohydrate-5; water-the remainder. 4kg of NaOH and 100 liters of water were added to the waste. The mixture was stirred with a stirrer and heated to 100 ℃. The homogenizing pump is then turned on. The hydrolysis process took 1 hour. After stirring for 1.5 hours by means of a frame stirrer, the hydrolysate was cooled to 40℃and 2% collagenase (2000 units/g), 0.05% protease (50000 units/g) and 0.01% lipase (2000000 units/g) were added to the total mass fraction of the material. The mixture was cooled to 25 ℃ and 55 mass% CuSO 4 (18% aqueous CuSO 4) of the hydrolysate and 18 mass% NH 4 OH (25% ammonia solution) of the hydrolysate content were added. Mixing was continued for 20 minutes until blue color appeared and the components were completely dissolved, as CuSO 4 and NH 4 OH were added to the hydrolysate to form a copper-ammonium-amino acid complex, which was a mixture of various complexes of the formula [ Cu (NH 3)3A]SO4, wherein A was an amino acid residue selected from 20 standard amino acids, part of the mixture of 20 standard amino sodium salts did not undergo complexation, copper hydroxy-amino complex was a combination of different complexes of the formula A-Cu (OH) 2, wherein A was an amino acid selected from 20 standard amino acids, i.e. a mixture of 20 complexes, each having a different amino acid residue selected from the 20 standard amino acids. As a result of the above procedure, suitable reagents for cleaning contaminated areas comprise a mixture of sodium salts of amino acids-20 standard amino acids, a surfactant-mixture of sodium salts of fatty acids having the structure C nH2n+1 COOH (where n=4-18), a combination of polysaccharide hydrolysates and copper-ammonium-amino acid complexes-copper-ammonium amino acid complexes based on 20 standard amino acids, with the following composition ratios in mass%: amino acid sodium salt-10; fatty acid sodium salt-5; copper hydroxy amino complex-7; copper-ammonium-amino acid complex-7; polysaccharide hydrolysate-5; water-the remainder.
Example 12
Example 12 differs from example 11 in that KOH was added to the waste material instead of NaOH. As a result, the claimed reagent for cleaning contaminated areas is obtained, which contains a mixture of potassium salts of amino acids-20 standard potassium salts of amino acids, a surfactant-a mixture of potassium salts of fatty acids having the structure of formula C nH2n+1 COOK (where n=4-18), a mixture of polysaccharide hydrolysates and copper-ammonium-amino acid complexes-a copper-ammonium-amino acid combination based on 20 standard amino acids, with the following composition ratios in mass%: amino acid potassium salt-10; fatty acid potassium salt-5; copper hydroxy amino complex-7; copper-ammonium-amino acid complex-7; polysaccharide hydrolysate-5; water-the remainder.
Based on examples 1-12, final product tests were performed on municipal sewage and sludge produced thereby. The claimed reagents also show similar results in the treatment of sewage from chemical, food and livestock facilities and sludge from the above-mentioned sewage treatment plants.
In the course of the test, 500mL of municipal sewage sludge with 92% humidity was treated. Thereafter, 1mL of a solution of the claimed reagent was added to the precipitate. The samples were stored at room temperature for 24 hours. Thereafter, the solid components in the sediment are completely flocculated and precipitated. The water portion is fully illuminated. The received sediment is treated with a reagent and then filtered and analyzed for the presence of a population of pathogens in the liquid and solid phases. Analytical data for the effect of the reagents described in examples 1-12 on municipal sewage are set forth in tables 1.1 and 2.1.
The reagent solution of the invention is adopted to treat 50m 3 mud surface cards, thereby solving the problem of sewage and sludge water. Within 24 hours after treatment, it was noted that the apparent fecal odour was completely lost, and the sediment separated from the aqueous phase and precipitated at the bottom of the card. The solid and liquid phases of the sludge are then analyzed to reveal the presence of the pathogen population and the concentration of heavy metal ions. Tables 1.2 and 2.2 set forth analytical data for the effect of the reagents described in examples 1-12 on sludge wastewater.
Based on the analysis of the specific reactions of amino acids and sugars, the reagent composition was determined using a conductivity method. The component measurement method comprises the following steps: GOST 18995.1-73, GOST32195-2013, GOST 34132-2017, GOST32195-2013.
Tables 1.1 and 1.2 show the results of treatment of wastewater with the reagent at a rate of 1 liter of reagent per 1m 3 of wastewater, and tables 1.2 and 2.2 show the results of treatment with the sludge reagent at a rate of 1 liter of reagent per 1m 3 of sludge. To ensure the desired degree of wastewater or wastewater sludge treatment, 0.6 to 1.5 liters of reagent is used per m 3 of sludge. The concentration is selected according to microbiological, parasitical, physicochemical parameters of the reference sample. The concentration is collected by processing the reference sample until regulatory results are obtained that can be used for further safe use of the waste.
What has been described above is a specific embodiment of the present invention. Other variations of the invention that do not alter its nature, as described in this specification, will also be apparent to the relevant expert. Accordingly, the present invention should be considered as limited formulations shown in the following table.
