Embodiment 1

[0027] On-site deodorization test was carried out at a garbage transfer station in Nanjing. Firstly, a pool with a serious rancid smell and a lot of acid gases such as hydrogen sulfide was selected, and the mixed solution A and the mixed solution B were mixed according to the mass ratio A:B=1:1.5. Dilute the mixture 10 times with water, stir evenly, and then spray it in the garbage pool. The mass percentage of each component is: 1% of steady-state chlorine dioxide; 20% of ferrous sulfate; 0.5% of nano titanium dioxide; and the balance of water.

[0028] (1) Preparation of mixed solution A and mixed solution B:

[0029] Put 500g of water into a conical flask, first add 25g of steady-state chlorine dioxide, stir until completely dissolved, and obtain a yellow-green clear solution. Then add 5g of nano-titanium dioxide in batches, continue to stir, and the solution becomes a light yellow milky emulsion, which is designated as mixed solution A. Add 200g of water to another Erlenm...

Embodiment 2

[0038] In a garbage transfer station in Nanjing, a pond with a serious irritating stench was selected, and the ability of the deodorant to remove ammonia was mainly investigated. Mixed solution A and mixed solution B are mixed according to the mass ratio A:B=1:0.5, the mixed solution is diluted 10 times with water, and sprayed in the garbage compression pool. The mass percentage of each component is: steady state chlorine dioxide 1%; ferrous sulfate 20%; nano-titanium dioxide 0.5%; the balance water.

[0039] The implementation method of this embodiment includes the preparation of the mixed solution A and the mixed solution B, the mixing, dilution and spraying of the original solution, and the detection of the deodorizing effect. Concrete operation method is with embodiment 1. SKY2000-NH 3 The data obtained by the type pump-suction ammonia detector shows that the deodorant prepared according to this method not only deodorizes thoroughly, but also reduces the odor concentrati...

Embodiment 3

[0041] In a waste transfer station in Nanjing, a pond with both putrid and foul odors was selected, and a comprehensive deodorization test was carried out on it. The mixed solution A and the mixed solution B are mixed according to the mass ratio A:B=1:1, the mixed solution is diluted 10 times with water, and sprayed on the garbage transfer station with a lot of mixed gases containing sulfur and nitrogen. The mass percentage of each component is: steady state Chlorine dioxide 1%; ferrous sulfate 20%; nanometer titanium dioxide 0.5%; balance water.

[0042] The implementation method of this embodiment includes the preparation of the mixed solution A and the mixed solution B, the mixing, dilution and spraying of the original solution, and the detection of the deodorizing effect. Concrete operation method is with embodiment 1. H on the scene 2 S, NH 3 Concentration testing, the results show that the deodorant can minimize the odor content, deodorization time can be maintained a...

Abstract

The invention discloses a deodorant for a garbage transfer station and a preparation method thereof, belonging to the technical field of deodorant preparation. The components of the deodorant and their mass percentages are: 16-20 parts of ferrous sulfate, 1-2 parts of steady-state chlorine dioxide, 0.5-1.5 parts of nanometer titanium dioxide and the balance of water. The preparation method first stirs water and steady-state chlorine dioxide to obtain a chlorine dioxide stock solution, then adds nano-titanium dioxide to the chlorine dioxide stock solution and stirs evenly to obtain a mixed solution A; Air bubbles are used to prepare mixed solution B; mixed mixed solution A and mixed solution B are mixed and evenly stirred to obtain the garbage transfer station deodorant of the present invention. The deodorant of the invention has the characteristics of high efficiency and durability, and is safe and nontoxic.

Description

Technical field: [0001] The invention belongs to the technical field of deodorant preparation, and relates to a deodorant for a garbage transfer station and a preparation method thereof, in particular to a water-based deodorant prepared by the interaction of titanium dioxide, chlorine dioxide and iron salt. technical background: [0002] As a non-toxic and environmentally friendly metal salt, ferrous sulfate is often used in the preparation of iron oxide pigments, water purifiers, preservatives, disinfectants, etc. Iron ions and low-valence sulfides will undergo oxidation-reduction reactions and metathesis reactions. According to these reactions, treating sulfur-containing odors or inhibiting the generation of odors can make the deodorization effect more thorough. The mechanism of iron ions to remove sulfide is different under acidic and alkaline conditions, specifically: under acidic conditions, hydrogen sulfide does not ionize, and has the following reaction: [0003] h ...
