Problems solved by technology

The emission of sulfide will cause the following problems: firstly, sulfide (such as hydrogen sulfide), hydrogen sulfide is a toxic gas, which is dangerous to the staff; secondly, hydrogen sulfide has obvious odor, which has adverse effects on production and life
The eutrophication of the water body will cause the pH to drop, and the pH drop will not only lead to the increase of hydrogen sulfide gas, but also the increase of heavy metal activity, which leads to an increased risk of diseases such as bone pain
[0003] In the prior art, the solution to the odor problem in the process of garbage disposal is mainly to control the odor by covering and spraying deodorants. However, the existing deodorants can only temporarily control the odor, and cannot stably control the pH value of the garbage. strong recurring odor

preparation example Construction

[0034] A preferred preparation process of the scavenger comprises: 1) adding water in the reactor, adding magnesium oxide while stirring, when the temperature is below 95°C (such as 65-95°C), adding an organic acid, and continuing to stir (continuously stirring time such as about 30 minutes); 2) add the suspending agent afterwards and continue to stir (continuous stirring time such as about 40 minutes); 3) add the biological bacteria afterwards (preferably add within 24 hours before the use of the purifying agent), and the pH of the final purifying agent The value is about 9.5-10.5.

[0035] In some specific and preferred embodiments, in terms of weight percentage, the raw material formula of the purifying agent includes magnesia 10-60%, organic acid 0.04-0.125%, suspending agent 0.0013-0.5%, and biological bacteria 0.1-0.5%, Others are water;

[0036] Further, the magnesium oxide raw material preferably has a purity ratio of magnesium oxide greater than 90%, and silicon diox...

Embodiment 1

[0050] A purifying agent for garbage deodorization, which is prepared by using the following raw materials in the following steps in terms of weight percentage: 1) adding water to a reaction kettle, adding magnesium oxide while stirring, and adding water for every 100 parts by weight of magnesium oxide 300 parts, when the temperature drops to 70°C after fully reacting, 2) add 1 part of organic acid (75% glacial acetic acid), and stir for 30 minutes; 3) add suspending agent (hydroxypropyl methylcellulose, the viscosity specification is 15,000mPa.s) 1 part, stirred for 40 minutes, 4) then added 1 part of biological bacteria (methyl mercaptan degrading bacteria), stirred for 5 minutes, the final concentration of the purifier was 36%, and the pH value was about 9.7. Test the deodorizing ability of the prepared purifying agent:

[0051] Use the decontamination agent for the landfill in progress, the dose rate is 60mg / m 3 to 120mg / m 3 wait. Hydrogen sulfide was monitored using a ...

Embodiment 2

[0053] A purifying agent for garbage deodorization, which is prepared by using the following raw materials in the following steps in terms of weight percentage: 1) adding water to a reaction kettle, adding magnesium oxide while stirring, and adding water for every 100 parts by weight of magnesium oxide 400 parts, when the temperature drops to 65°C after full reaction, 2) Add 1 part of organic acid (citric acid) and stir for 30 minutes; 3) Then add suspending agent (hydroxypropyl methylcellulose, viscosity specification is 15,000 mPa.s) 1 part, stirred for 40 minutes, 4) then added 1 part of biological bacteria (methyl mercaptan degrading bacteria group), stirred for 5 minutes, the final concentration of the purifying agent was 29%, and the pH value was about 9.5.

[0054] Use the prepared decontamination agent to landfill the site in progress, and the dose rate is 100mg / m 3 to 330mg / m 3 wait. Hydrogen sulfide was monitored using a hydrogen sulfide detector and ammonia and me...

Abstract

The invention discloses a rubbish deodorizing purifying agent, a preparation method thereof and a rubbish deodorizing method. The purifying agent is a solid-liquid mixture with a pH of 9.5 to 10.5 and its components include magnesium hydroxide, an organic acid, a suspending agent, biological Bacteria and water, wherein the mass content of magnesium hydroxide is 10-80%, the mass content of the suspending agent is 0.001-5%, and the mass content of biological bacteria is 0.001-5%. The preparation method of the purifying agent includes hydrating magnesium oxide and water to generate magnesium hydroxide, adding organic acid, suspending agent and biological bacteria when the temperature is below 95°C. The garbage deodorization method is to spray the cleaning agent into the garbage. The cleaning agent of the present invention is used to deodorize garbage, the pH value of the garbage can be kept stable (fluctuation range is less than 0.5), the deodorizing effect is maximized, and the odor will not recur. In addition, the cleaning agent of the present invention is safe and harmless, and has good fluidity , can be put into use directly, easy to use.

Description

technical field [0001] The invention relates to the technical field of garbage landfill, in particular to a purifying agent with garbage deodorizing effect and a preparation method thereof, and also relates to a garbage deodorizing method. Background technique [0002] With the development of the economy, the discharge of domestic and industrial waste is increasing, which brings great pressure to the environment. The most important component that causes pollution in domestic and industrial waste is sulfide. In addition, garbage odor also contains a certain proportion of methane, methyl mercaptan, ammonia and so on. Sulfate in water-containing waste is reduced to sulfide by sulfate-reducing bacteria (SRB). The emission of sulfide will cause the following problems: firstly, sulfide (such as hydrogen sulfide), hydrogen sulfide is a toxic gas, which is dangerous to the staff; secondly, hydrogen sulfide has obvious odor, which has adverse effects on production and life. Severa...
