Embodiment 1

[0028] The preparation method of domestic waste deodorant comprises the following steps: 100g iron powder (mesh number is 200) is placed in 500mL containing 2.75% H 2 o 2 In the aqueous solution, the modified iron powder was obtained after ultrasonic treatment at 40°C for 2 hours (ultrasonic frequency = 40kHz, power = 200W), and centrifuged. 90.0% by mass of modified iron powder, 7.5% of sodium dodecylbenzenesulfonate, 1.5% of sodium carbonate and 1.0% of alkaline protease were evenly mixed to prepare a deodorant for treating domestic waste.

[0029] Take 5kg of uniformly mixed household garbage and place them in 25L round plastic buckets, and set them as the experimental group and the control group. In the experimental group, the deodorant was diluted 120 times with water, stirred evenly, and sprayed on the surface of domestic garbage, and the spraying mass percentage of the deodorant was 0.05%. The control group was not sprayed with deodorant. Seal the plastic barrels of ...

Embodiment 2

[0035] The preparation method of domestic garbage deodorant comprises the following steps: 100g iron powder (400 mesh) is placed in a solution containing 2.75% H 2 o 2 solution, ultrasonic treatment at 40°C for 3 hours (ultrasonic frequency = 40kHz, power = 200W), and centrifugation to obtain modified iron powder. 93.0% by mass of modified iron powder, 5.2% of sodium dodecylbenzenesulfonate, 1.2% of sodium carbonate and 0.6% of alkaline protease were evenly mixed to prepare a deodorant for domestic waste.

[0036] Take 5kg of uniformly mixed household garbage and place them in 25L round plastic buckets, and set them as the experimental group and the control group. In the experimental group, the deodorant was diluted 160 times with water, stirred evenly, and sprayed on the surface of domestic garbage. The sprayed mass percentage of the deodorant was 0.20%. The control group was not sprayed with deodorant. Seal the plastic barrels of the experimental group and the control gro...

Embodiment 3

[0041] The preparation method of household garbage deodorant comprises the following steps: 100g iron powder (the number of mesh is 800) is placed in containing 2.75% H2 o 2 solution, ultrasonic treatment at 40°C for 5 hours (ultrasonic frequency = 40kHz, power = 200W), and centrifugation to obtain modified iron powder. 95.0% by mass of modified iron powder, 3.8% of sodium dodecylbenzenesulfonate, 0.8% of sodium carbonate and 0.4% of alkaline protease were evenly mixed to prepare a deodorant for treating domestic waste.

[0042] Take 5kg of uniformly mixed household garbage and place them in 25L round plastic buckets, and set them as the experimental group and the control group. In the experimental group, the deodorant was diluted 250 times with water, stirred evenly, and sprayed on the surface of domestic garbage, and the spraying mass percentage of the deodorant was 0.50%. The control group was not sprayed with deodorant. Seal the plastic barrels of the experimental group ...

Abstract

The invention relates to a deodorant for treating domestic garbage and a preparation method as well as a use method thereof. The deodorant for treating domestic garbage comprises the following components in percentage by mass: 90.0-95.0 percent of modified iron powder, 3.8-7.5 percent of sodium dodecyl benzene sulfonate, 0.8-1.5 percent of sodium carbonate and 0.4-1.0 percent of alkaline protease. The preparation method of the deodorant comprises the following step of: uniformly mixing 90.0-95.0 percent of modified iron powder, 3.8-7.5 percent of sodium dodecyl benzene sulfonate, 0.8-1.5 percent of sodium carbonate and 0.4-1.0 percent of alkaline protease to obtain the deodorant for treating domestic garbage. The use method of the deodorant comprises the following step of: spraying the deodorant to the surface of the domestic garbage, wherein the spray amount is that 0.05-0.20 percent by mass of deodorant is sprayed to every ton of domestic garbage. The deodorant provided by the invention has the advantages of convenience for use, easiness for operation, high reliability and the like; and after the domestic garbage is treated by the method provided by the invention, the removal rate of hydrogen sulfide is 65-70 percent within 96 hours, the odor concentration can be reduced by 42-61 percent, and the release of odor gas can be obviously reduced.

Description

technical field [0001] The invention belongs to the technical field of domestic waste treatment, and relates to a deodorant for treating domestic waste, a preparation method and a use method thereof. Background technique [0002] The rapid growth of municipal solid waste has become a thorny problem faced by cities all over the world. In China, nearly 150 million tons of domestic waste is generated every year. Pollution prevention and control of domestic waste during transfer and landfill, especially odor control, has become a major concern in the treatment and disposal of domestic waste. Compared with the sorted garbage in most developed countries, domestic garbage in my country has the characteristics of high mixing, high moisture content, and high organic components, which are particularly prone to odor, and pollution control and treatment are also very difficult. [0003] Due to the biodegradation process of domestic waste, especially the catabolism of proteins, sugars,...
