Embodiment 1

[0030] Deodorant raw materials include 60 parts of active free radical sources, 0.4 parts of active stimulators, 15 parts of balance stabilizers, 24.6 parts of long-lasting accelerators by weight, and the weight ratio of each free radical source is halogen free radical source: SR free radical Source: hydroxyl radical source = 13:47:14.

[0031] In this embodiment, the halogen free radical source is calcium chlorate. In this embodiment, calcium chlorate is replaced by one of sodium hypochlorite and sodium hypobromite according to the same weight part, or replaced by chlorine according to the same weight part. The mixture of calcium chloride, sodium hypochlorite, and sodium hypobromite is a qualified deodorant, and there is no significant difference in the properties of the products obtained.

[0032] In this embodiment, the SR free radical source is potassium monopersulfate. In this embodiment, potassium monopersulfate is replaced by one of sodium persulfate and calcium persulf...

Embodiment 2

[0036] Deodorant raw materials include 65 parts of active free radical sources, 0.6 parts of active stimulators, 10.4 parts of balance stabilizers, and 24 parts of long-lasting accelerators by weight, and the weight ratio of each free radical source is halogen free radical source: SR free radical Source: hydroxyl radical source = 15:50:11

[0037] In this embodiment, the source of halogen free radicals is sodium hypochlorite. In this embodiment, sodium hypochlorite is replaced by one of calcium chlorate and sodium hypobromite in equal parts by weight, or by sodium hypochlorite and chlorine in equal parts by weight. Calcium acid, the mixture of sodium hypobromite, all get qualified deodorant, and the obtained product property does not have obvious difference.

[0038] In this embodiment, the SR free radical source is sodium persulfate. In this embodiment, sodium persulfate is replaced by one of potassium monopersulfate and calcium persulfate according to the same weight part, o...

Embodiment 3

[0042] Deodorant raw materials include 76 parts of active free radical sources, 1 part of active stimulator, 8 parts of balance stabilizers, 15 parts of long-lasting accelerators by weight, and the weight ratio of each free radical source is halogen free radical source: SR free radical Source: hydroxyl radical source = 19:47:20.

[0043] In this embodiment, the halogen free radical source is sodium hypobromite. In this embodiment, sodium hypobromite is replaced by one of sodium hypochlorite and calcium chlorate in equal parts by weight, or by The mixture of sodium hypobromite, sodium hypochlorite, and calcium chlorate is a qualified deodorant, and there is no significant difference in the properties of the products obtained.

[0044] In this embodiment, the SR free radical source is calcium persulfate. In this embodiment, the calcium persulfate is replaced by one of sodium persulfate and potassium monopersulfate according to the same weight part, or according to the same weigh...

Abstract

The invention discloses an SRR deodorant for treating sludge stink and a deodoration method by using the SRR deodorant. The deodorant is prepared from a free radical source, an active stimulator, a balance stabilizer and a long-acting promoter, wherein the free radical source is a mixture of a halogen free radical source, an SR free radical source and a hydroxyl free radical source; the deodorant can be used for sludge deodoration, and due to addition of the halogen free radical source in the deodorant, the problem that humic amine stink is difficultly solved by separated use of the SR free radical source and the hydrogen peroxide free radical source. High oxidation potentials such as SR free radical, hydroxyl free radical and halogen free radical produced after the deodorant is dissolved and activated in water can decompose almost all rhodanides, sulfur-containing organic substances, humic amine and other non-biodegradable stink compounds and toxic organic substances in the sludge, and the non-biodegradable stink compounds and toxic organic substances can be thoroughly converted into harmless inorganic substances such as inorganic sulfates, carbon dioxide (CO2) and water (H2O), and the stink of the sludge treated by adopting the technology can be alleviated to last for two to three days.

Description

technical field [0001] The invention relates to a sludge treatment technology, in particular to an SRR deodorant for treating sludge stench and a deodorization method thereof. Background technique [0002] Volatile substances produced and released during sludge biological fermentation. The results of GC-MS analysis showed that the components of the volatile substances released from the surface of the fermentation tank during the sludge biological fermentation process were complex, mainly including ketones (acetone, 2-butanone, 3-methyl-2-butanone, 1 -Pentanone, 2-pentanone, 3-pentanone, cyclopentanone, 2-hexanone, 2-heptanone, 2-nonanone, fenzone, 2-methylcyclopentanone, 6-methyl-2 -heptanone, a total of 13 kinds), aromatic hydrocarbons (toluene, ethylbenzene, m-xylene, styrene, 1-ethyl-2-toluene, 1,3,5-trimethylbenzene, 1,2,4-trimethylbenzene , 1-methyl-2-isopropylbenzene, 1-ethyl-3-toluene, 1,4-dichlorobenzene, naphthalene, a total of 11 kinds), alcohol (ethanol, isoprop...
