Problems solved by technology

The method has a wide variety of raw materials, complicated steps, and poor deodorization adaptability
Chinese patent CN1145592A discloses a deodorant and its deodorizing method. The deodorant is made of copper oxide, manganese oxide and silver nitrate, and is carried on a carrier substrate mainly composed of activated carbon. It is mainly used to remove hydrogen sulfide, various mercaptans, ammonia and amines in malodorous gases, and it is not effective for the removal of low molecular weight organic matter.

Embodiment 1

[0026] Taking the removal of the malodorous gas produced by the garbage exposed at the municipal solid waste transfer station and transfer station as an example, the preparation method and application effect of the high-efficiency deodorizing liquid for the malodorous gas of domestic waste are expounded. Its preparation method mainly comprises the following steps:

[0027] (1) Preparation of catalytic solution for hydrogen sulfide oxidation

[0028] 1. Dissolve 0.1-1 mol metal complexing agent, for example, ethylenediaminetetraacetic acid (EDTA) or dithiocarbamate in 1-100 liters of water;

[0029] 2. Slowly add an equivalent amount of ferrous salt, such as FeSO, under stirring 4 ·7H 2 O or ferric chloride, ferric nitrate, ferric acetate, ferric citrate, etc. form a light green solution;

[0030] 3. Use an air pump to feed air into the above solution to change the color of the solution from light green to light red to obtain the hydrogen sulfide oxidation catalytic solution...

Embodiment 2

[0052] Taking the removal of malodorous gas from landfills or livestock and poultry breeding sites as an example, the preparation method and application effect of high-efficiency deodorizing liquid for odorous gas from domestic garbage are expounded.

[0053] The preparation method is the same as above. Dilute the prepared high-efficiency deodorizing liquid for odorous gas of domestic waste, and then spray it widely and repeatedly on the landfill or the cages of livestock and poultry farms to produce a good deodorizing effect.

Abstract

The invention discloses an efficient deodorant liquid used for removing malodorous gas of household wastes and a preparation method thereof, belonging to the technical field of gas purification products. The basic components of the deodorant liquid are hydrogen sulfide oxidation catalysis solution and nitrobacteria culture suspension, and the deodorant liquid is obtained by uniformly mixing the hydrogen sulfide oxidation catalysis solution, the nitrobacteria culture suspension and water in a proper proportion. The efficient deodorant liquid for removing malodorous gas of household wastes can quickly oxidize and decompose the malodorous components in the malodorous gas such as hydrogen sulfide, ammonia, low molecular organic acids, which are then transformed and degraded into innocuous elemental sulfur, nitrate, water, carbon dioxide, and the like, thereby quickly eliminating stench. Therefore, the deodorant liquid can be widely applied to refuse landfills, refuse transfer stations, animal feeding huts, and the like places. The efficient deodorant liquid for removing malodorous gas of household wastes and the preparation method thereof disclosed by the invention has the advantages of simplicity, reliability, low cost, remarkable deodorization effect, innocuity and harmlessness to human body, no stimulation and secondary pollution, as well as broad application prospect.

Description

1. Technical field [0001] The invention relates to a high-efficiency deodorizing liquid for malodorous gas of domestic garbage and a preparation method thereof, belonging to the technical field of gas purification products. More specifically, it is a high-efficiency deodorizing liquid for malodorous gas and a preparation method thereof that can be widely used in landfills, garbage transfer stations, livestock sheds and other places. The manufacturing method is simple, the cost is low, the deodorizing effect is remarkable, the human body is non-toxic, harmless, non-irritating and does not produce secondary pollution. 2. Technical background [0002] The malodorous gas components can be produced under aerobic and anaerobic conditions, but the main odorous substances come from the anaerobic fermentation process. During the stacking or composting of domestic garbage, when the oxygen is sufficient, the organic components in the garbage, such as protein, will produce irritating g...
