Embodiment 1

[0031] Example 1: An on-site deodorization test was carried out at a garbage transfer station in Nanjing. First, a pool with a severe rancid smell was selected, and the ability of the deodorant to remove the odor of hydrogen sulfide was focused on. The mass percentage of each component is: ascorbic acid 1%; ferrous sulfate 20%; copper sulfate 3%; citric acid 6%; glyoxal 1.6%; glutaraldehyde 1.4%; 1,2-propanediol 1%; 0.3% trimethylammonium bromide; 3-4 drops of essence; the remaining amount of water. The specific operation steps are as follows:

[0032] (1) Preparation of stock solution

[0033] In 39.6g of water, first add 1g of ascorbic acid, stir until completely dissolved to obtain a clear solution. Then add 36.6g FeSO in batches 4 ·7H 2 O, continue to stir, the solution turns light green. Then, under the condition of stirring, add 4.7g CuSO 4 ·5H 2 O, the solution turned bright green at this time. Continue to stir, and gradually add 6g of citric acid, the solution ...

Embodiment 2

[0041] Example 2: A pond with a severe irritating stench was selected at a certain garbage transfer station in Nanjing, and the ability of the deodorant to remove ammonia was mainly investigated. The mass percentage of each component is: ascorbic acid 1%; ferrous sulfate 10%; copper sulfate 2%; citric acid 3%; glyoxal 3%; glutaraldehyde 3%; 1,2-propylene glycol 3%; dodecane 0.2% trimethylammonium bromide; 3-4 drops of essence; the rest of water.

[0042] The implementation method of this embodiment includes the preparation of the stock solution of the deodorant, the dilution and spraying of the stock solution, and the test of the deodorant effect. Concrete operation method is with embodiment 1. SKY2000-NH 3 The data obtained by the new type pump-suction ammonia detector shows that the deodorant prepared according to this method not only deodorizes thoroughly, but also reduces the odor concentration to 0.016mg / m within 20 minutes after spraying. 3 Below, and the deodorizat...

Embodiment 3

[0043] Example 3: A pool with both rancid and foul odors was selected at a garbage transfer station in Nanjing, and a comprehensive deodorization test was carried out on it. The mass percentage of each component is: ascorbic acid 2%, ferrous sulfate 18%, copper sulfate 2.5%, citric acid 4%, glyoxal 2.5%, glutaraldehyde 2.5%, 1,2-propanediol 2%, dodecane 0.4% trimethylammonium bromide, 3-4 drops of essence, and the rest of water.

[0044] The implementation method of this embodiment includes the preparation of the stock solution of the deodorant, the dilution and spraying of the stock solution, and the test of the deodorizing effect. The specific operation method is the same as in Example 1. H on the scene 2 S, NH 3 Concentration testing, the results showed that the deodorant has a high-efficiency deodorizing effect, and the odor can be obviously reduced within 30 minutes after spraying; after one hour, the site basically does not smell the odor. The instrument test data sho...

Abstract

The invention discloses a chemical type deodorant for a waste transfer station and a preparation method thereof, and belongs to the technical field of deodorant preparation. The deodorant comprises the following components in percentage by mass: 55 to 58% of water, 1 to 3% of an antioxidant, 10 to 20% of a desulphurizing reagent, 2 to 4% of an accelerant, 3 to 7% of an organic acid, 2 to 6% of an aldehyde solution, 1 to 3% of 1, 2-propylene glycol, 0.2 to 0.4% of a surfactant, and 0.1 to 0.25% of essence. The preparation method of the deodorant comprises the following steps: firstly, preparing an antioxidant water solution; then, adding the desulphurizing reagent to obtain a green solution; adding the accelerant to the green solution to obtain a blue-green solution after stirring; adding the organic acid to the blue-green solution to obtain a dark-green solution; adding the aldehyde solution and continuously stirring; then adding 1, 3-propylene glycol, the surfactant and the essence and fully stirring to prepare the deodorant provided by the invention. The deodorant provided by the invention has the benefits of good deodorization performance and long-acting deodorization, and further can be degraded automatically, thereby having no secondary pollution to the environment.

Description

Technical field: [0001] The invention belongs to the technical field of deodorant preparation, and relates to a chemical type garbage transfer station deodorant and a preparation method thereof, in particular to an aqueous solution system in which iron salts and aldehydes interact together as a household garbage deodorant. Background technique: [0002] With the rapid development of my country's economy, people's living standards continue to improve. For urban residents, while ensuring the quality of life, they pay more attention to the comfort and hygiene of the living environment. However, the huge population in the city produces up to thousands of tons of domestic waste every day. If these domestic wastes are piled up casually or not disposed of in time, after being washed by rainwater, a large number of bacteria will grow, and the organic matter in the waste is easy to rot and deteriorate, and release horrific emissions. Disgusting stench. These malodorous components ma...
