Problems solved by technology

[0003] The physical method is to seal the entire production workshop, use negative pressure to pump out the gas in the workshop, and put in the gas cabinet with adsorbent to absorb the odorous substances to achieve the effect of deodorization. However, after the adsorbent is saturated, it cannot be analyzed and reused. , the use cost is high, and the adsorbent that adsorbs the odorous gas is a hazardous waste, and the treatment cost is extremely high. The chemical method uses the fragrance to reduce the odor, but it only plays a role in covering the odor. When the concentration of the odorous gas is high or the fragrance is completely volatilized Finally, it does not have a good deodorizing effect. The biological method is to extract the gas in the workshop and treat it through the microorganisms in the water. Because the water dissolves the gas and the efficiency is limited, the treatment effect is not good. Therefore, the current Need to prepare a new type of deodorant

Abstract

The invention relates to a deodorant for removing malodor generated in sludge drying, and a preparation method and an application thereof. The deodorant is prepared from 30-98% of water, 0.50-20% of an emulsifier, 0.01-30.00% of a pH regulator, 1.00-25.00% of Moringa Pterygosperma seed oil, 0.0001-1% of a preservative, 0.0001-1% of a perfume, 0.0001-1% of a thickener and 0-1% of a pigment. The deodorant for removing malodor generated in sludge drying covers the emitted malodor by reducing the generation amount of the malodor in the sludge drying process and using the perfume, so the malodor problem in the sludge drying process is fundamentally solved.

Description

technical field [0001] The invention relates to the technical field of sludge drying treatment, in particular to a deodorant for removing foul odor generated by sludge drying, a preparation method and application thereof. Background technique [0002] During the storage and drying process of activated sludge, because it contains a large amount of water and organic matter, it will produce a large amount of strong irritating odor gas, which will have a direct or indirect impact on the surrounding environment and human health. The released malodorous gas removal technologies mainly include physical, chemical and biological methods. [0003] The physical method is to seal the entire production workshop, use negative pressure to pump out the gas in the workshop, and put in the gas cabinet with adsorbent to absorb the odorous substances to achieve the effect of deodorization. However, after the adsorbent is saturated, it cannot be analyzed and reused. , the use cost is high, and ...
