Description

The invention relates to the field of hygiene and sanitation and can be used for disinfection and sanitation of indoor air in the presence of people and/or animals, as well as for purifying the air from unpleasant odors.

Humic substances are amorphous dark brown high-molecular natural organic formations, characterized by instability of chemical composition and are an integral part of the organic matter of soil, bottom sediments, peats, etc. Humic substances are powerful stimulators of plant growth and development and are widely used in the national economy as components of organomineral fertilizers

The agrochemical value of peat is determined mainly by its organic part (humic and fulvic acids). However, due to the low availability of organic matter, the original peat exhibits weak fertilizer properties. The activator of peat organic matter can be aqueous solutions of alkalis and ammonia, which extract humic substances in the form of water-soluble humates (Orlov D.S. Humic substances in the biosphere. // Soros Educational Journal. - 1997. - No. 2. - P.56-63 ).

A deodorizing agent for purifying air from unpleasant odors is known, containing a filler, an odor-absorbing agent and a fragrance. As an odor absorption agent, the product contains components selected from the group: sodium bicarbonate, potassium bicarbonate, sodium tetraborate, magnesium oxide, and as a filler - adsorbents selected from the group: aluminosilicates, silica gels, adsorbents of plant origin: bran, meal, dried and crushed corn cob cores. The components are taken in the following ratio, wt.%: odor absorption agent - 1.0-98.0; fragrances - 0.2-1.0; filler - the rest. The technical result is the complete elimination of unpleasant odors in the premises and ensuring a sustainable deodorizing effect (patent RU 2293576, A61L 9/01, published 02.20.2007).

This product, however, only serves to sanitize indoor air and is not a disinfectant.

A disinfectant-detergent is known containing, wt.%, a halogen-containing derivative of the hydantoin series (2.0-40.0), 5,5-dimethylhydantoin (1.0-20.0), anionic surfactants (3.0 -6.0), corrosion inhibitor (1.0-10.0), alkaline detergent components (4.0-10.0), water-soluble filler (89.0-14.0) (patent UA 70418, A61L 2/ 16, published October 15, 2004). The product is used for cleaning, washing and sanitation.

An aerosol product is known for the sanitation and disinfection of air in livestock buildings, containing silver nanoparticles (1-100), copper nanoparticles (10-200), 10% glycerin (50,000-100,000) and deionized water (up to 1 l) in mg/l. (patent UA 34932, A61L 2/22, published 04/07/2008). The product is targeted at a wide range of microorganisms and allows you to effectively inactivate microflora of various etiologies, and also makes it possible to use it in the presence of animals.

Thanks to the use of silver and copper nanoparticles, this product is quite expensive and difficult to manufacture, since the colloidal solution is obtained by dispersing silver and copper granules in water using pulses of electric current.

A known product for disinfection and sanitation of air through fine spraying contains, wt.%: extract of steroid saponins from Yucca Schidigera plants - 0.5-60.0, sodium benzoate - 0.05-2.0, essential oils of plants - 0.5 -2.0, deionized water - the rest (patent RU 2407547, A61L 9/013, A61L 9/14, published 12/27/2010), selected as a prototype. The invention makes it possible to provide air disinfection using an easy-to-manufacture, environmentally friendly and biodegradable product.

The disadvantages of the known product lie in its insufficient biological activity, and they may be due to the lack of non-volatile and non-volatile biologically active components of pine, as well as the inaccessibility of raw materials (Yucca Schidigera).

The objective of the claimed invention is to develop a method for producing a liquid odor absorber that does not contain allergenic additives: fragrances, extracts or oils that mask unpleasant odors, safe for the respiratory system and human skin, harmless to animals, based on ingredients of natural origin.

The problem is solved by the fact that the method of obtaining a liquid odor absorber consists in reagent processing of raw materials, peat is used as a raw material, when interacting with water until a hydromodulus of 12:1 is reached, followed by the addition of an aqueous solution of ammonia and hydrogen peroxide and heating, separation of the solid phase, in this case, the peat suspension, after reaching the hydromodule, is subjected to mechanical activation in a rotary-pulsation apparatus, with the frequency regulator of the apparatus indicating 45 Hz in a closed loop for 10 minutes, after which heating is carried out at a temperature of 115-130°C for 3 hours at adding 20-25% concentrated aqueous ammonia and 20-37% concentrated solution of hydrogen peroxide to an absolutely dry mass of peat, without subsequent concentration of the liquid phase.

Examples of specific implementations of the invention are given below.

Example 1

1000 g of sedge peat with a moisture content of 15% are loaded into the buffer tank of a rotary-pulsation apparatus, moistened with 8000 ml of water until the hydromodulus reaches 9.5:1, when the frequency regulator of the apparatus reads 42 Hz, mechanical activation of the pulp is carried out in a closed circuit for 5 minutes, after which the pulp is loaded into an autoclave, 100 ml of a 25% ammonia solution is added, which corresponds to 250 ml of a 10% ammonia solution or 5.7 wt.% per 100 ml of a 30% hydrogen peroxide solution, which corresponds to 300 ml of a 10% solution. hydrogen peroxide or 6.8 wt.%.

The autoclave is closed and the heating is turned on. Further processing is carried out at 115°C for four hours with stirring. The resulting suspension is separated by centrifugation.

The resulting liquid phase was sprayed over organic waste from an industrial poultry farm using a spray bottle. The waste was a mixture of chicken waste and sawdust with a characteristic unpleasant odor. The consumption was 15 g of the STOPZAP product per 1 square meter of waste. 15 minutes after spraying, no unpleasant odors were detected by factory employees throughout the irrigated area. When observing the waste for 10 days, no smell appeared.

Example 2

1000 g of sedge peat with a moisture content of 15% are loaded into the buffer tank of a rotary-pulsation apparatus, moistened with 8000 ml of water until the hydromodulus reaches 9.5:1, when the frequency regulator of the apparatus reads 42 Hz, mechanical activation of the pulp is carried out in a closed circuit for 5 minutes, after which the pulp is loaded into an autoclave, 100 ml of a 25% ammonia solution is added, which corresponds to 250 ml of a 10% ammonia solution or 5.7 wt.% per 100 ml of a 30% hydrogen peroxide solution, which corresponds to 300 ml of a 10% solution. hydrogen peroxide or 6.8 wt.%.

The autoclave is closed and the heating is turned on. Further processing is carried out at 115°C for four hours with stirring. The resulting suspension is separated by centrifugation.

The resulting liquid phase was sprayed using a spray bottle over the pet's tray with toilet filler, which was sawdust granules without fragrance. Before spraying, the litter had a persistent odor of pet waste. After spraying 5 grams of the STOPZAP product, no odor was detected after 15 minutes. Thanks to odor removal and daily irrigation of the filler with the specified product, it was possible to increase the use of a single tray load to 10 days.
