- a known composition for detoxification of sewage treatment plants containing hydrates of sodium or potassium salts of a mixture of amino acids, alkali and water (Friedman AL and other organomineral compositions based on sewage sludge from sewage treatment plants. M. Non-Profit Partnership "Chemical and Technological Scientific Center ”, M., 2000, pp. 75-87) [1].
- the effectiveness of this known composition is not high enough.
- a known method of detoxification of sludge from treatment plants by their treatment with a detoxifier [1].
- a composition is used containing hydrates of sodium or potassium salts of a mixture of amino acids, alkali and water.
- the technical result achieved by the present invention is to increase the efficiency of detoxification of sludge from treatment facilities.
- the specified technical result is achieved by the fact that the composition for detoxification of sewage treatment plants containing hydrates of sodium or potassium salts of a mixture of amino acids and hydrates of sodium or potassium salts of low molecular weight peptides obtained by water-heat treatment in the presence of alkali waste containing animal proteins, water and alkali , in the following ratio of components, May%: hydrates of sodium or potassium salts of a mixture of amino acids 8.2-9.2 hydrates of sodium or potassium salts of low molecular weight peptides Dov 3.6-4.2 alkali 0.05-0.06 water the rest.
- the specified technical result is achieved in the method of detoxification of sludge from treatment plants by their treatment with a detoxicant due to the fact that the composition according to p.
- V is the flow rate of IM solution of a detoxicant, l / m 3 ; t - the content of heavy metal in the cleaned sludge in terms of the absolutely dry substance of the sludge, g / kg, and a detoxicant is consumed with an excess of 20-30% relative to the calculated amount.
- Example 1 In a reactor with a capacity of 250 l, 108 l of water is loaded, 11.5 kg of sodium hydroxide are added in portions of 3 kg and then 60 kg of waste containing animal proteins (hair tows of cloth-felting production, waste hair from ventilation collection during the initial processing of wool, waste of fur dressing, production of valency products), tamping them if necessary.
- the ratio of waste: water: alkali is 1: 1.8:
- the steam supply valve is opened and the reaction mass is heated until circulation begins through the pipeline supplying steam to the expansion vessel — the refrigerator, and through the pipeline returning condensate to the reactor.
- the process is carried out at a temperature of 120 0 C. With a complete supply of steam, the mass is kept in a state of circulation for 75 minutes. Block feed steam into the reactor and incubated for 15 minutes after the termination of circulation. Shake the reactor lid, add water to a total reaction volume of 200 l and mix the mixture for 15 minutes.
- the reaction mixture is drained through a filter into a decanter. Get 2M aqueous solution of detoxicant - composition according to claim 1.
- sodium salt hydrates of a mixture of amino acids (alanine, valine, glycine, leucine, isoleucine, proline, phenylalanane, oxoproline, serine, tyrosine, threonine, arginine, histidine, lysine, oxylysine, cysteine, cystine, methionone, aspartic acid and glutamic acid) - 9.2; hydrates of sodium salts of low molecular weight peptides - 3.6, sodium hydroxide - 0.05 (free alkali content of 0.08 mol / l); the rest is water.
- Example 2 sodium salt hydrates of a mixture of amino acids (alanine, valine, glycine, leucine, isoleucine, proline, phenylalanane, oxoproline, serine, tyrosine, threonine, arginine, histidine, lysine, oxy
- Example 3 114 liters of water are loaded into a 250-liter reactor, 12 kg of potassium hydroxide are added in portions of 2 kg and then 60 kg of waste containing animal proteins (tanning leather, substandard fur and leather raw materials), ramming them if necessary.
- the steam supply valve is opened, the reaction mass is heated until circulation begins through the pipeline supplying steam to the expansion vessel — the refrigerator, and through the pipeline returning condensate to the reactor.
- the process is carried out at a temperature of 180 0 C.
- the ratio of waste: water: alkali is 1: 1.9: 0.25.
- the mass is kept in a circulated state for 15 minutes. Block the steam supply to the reactor and incubated for 10 minutes after the cessation of circulation.
- Example 4 The sludge of urban wastewater treatment plants, placed on a sludge map with a moisture content of 61% in the amount of PO t (separated part of the sludge map), was treated with irrigation with the composition according to claim 1, obtained according to example 1.
- the composition was pre-diluted to a concentration of 0.1 mol / l
- the precipitate contained (mg / kg dry matter): Cu - 795, Zn - 1530, Ni - 275, Cr - 553, Pb - 120, Cd - 98, Co - 20.
- the required amount of composition according to item l was calculated based on a mathematical expression:
- V is the consumption of detoxicant IM concentration, l / m-, t is the content of heavy metal in need of detoxification in the sediment, calculated on absolutely dry substance g / kg.
- the amount of detoxicant was calculated as PO 1 of a 0.1 molar solution. Irrigation of the surface of the sediment was carried out using a distribution device that moves along the boundaries of the sludge site. 132 L of a 0.1 molar reagent solution (1, 2-fold excess) was consumed during processing for 8 hour. The treated part of the sludge map was kept for 25 days, periodically measuring the pH. On the 15th day, the pH reached 7.6 and then did not decrease. Treated sediment has a smell of soil.
- the resulting organomineral composition is non-toxic to living organisms and is a substance of hazard class 4.
- GOST P 17.4.3.07-2001 it can be used to restore the productivity of disturbed lands for the purpose of forestry and recreational direction of their restoration, as well as as raw materials for the preparation of organic fertilizers by composting and vermicomposting.
- composition according to the invention obtained by the method according to the invention, provides a high detoxification efficiency 'of sludge from treatment facilities.

L'invention s'utilise dans la détoxication des sédiments provenant des installations d'épuration. Selon cette invention, pour détoxiquer les sédiments provenant des installations d'épuration on détecte la présence de métaux lourds dans ces sédiments et on calcule la quantité nécessaire d'une composition qui comprend de 8,2 à 9,2 % en masse d'hydrates des sels sodiques ou potassiques d'un mélange d'acides aminés; de 3,6 à 4,2 % en masse de peptides, de 0,05 à 0,06 % en masse de peptides, le reste étant constitué d'eau. La composition est obtenue au moyen traitement aquatique et thermique, en présence d'alcalis, de déchets contenant des protéines animales. Les déchets, l'eau et les alcalis sont présents dans des rapports suivants 1: (1,8-2,0): (0,19-0,37), et le traitement est effectué à une température de 120° à 180° C pendant 25 à 90 min.
