The detection and evaluation of garbage deodorants have always been a headache, and the difficulty lies in how to confirm the monitoring items and how to detect the confirmed items. The method used is to artificially create an odor source (fresh garbage, garbage leachate, or various garbage mixtures), and to reflect the deodorization effect of this product by testing its background value and the air target (ammonia, hydrogen sulfide, odor concentration, etc.) after spraying the deodorant. However, the method also has certain uncontrollability and randomness, and the industry has always sought a consistent standard to regulate the detection of deodorants.

According to the new label, the definition of daily waste deodorants is: products used to mask or reduce the odor of daily waste, including physical deodorants, chemical deodorants, biological deodorants, and plant deodorants. Based on the experience of the editor:

Physical deodorants and chemical deodorants are commonly used in the fixed pollution source emission gas collection and treatment stage, and various types of deodorization equipment such as physical packing towers and chemical washing towers are commonly seen;

Biological deodorants can be used in biological deodorization towers or biological filters to achieve deodorization through the reaction of microorganisms and odorous gases. They can also be used in the intermediate stage of daily garbage composting, where deodorants are directly mixed into the compost according to their proportion, and the occurrence of odor is reduced through microbial reaction; It can also be used for deodorization of ambient air without arranged emissions, through manual spraying, pipeline spraying, or air cannon spraying to achieve the purpose of suppressing the occurrence and spread of odor.

Plant deodorants are mostly used for the use of unorganized emissions of environmental air. Good plant deodorants are expensive and can even be used as air fresheners. They are widely used in the control of environmental air quality in landfill and waste transfer stations.

The recent "public toilet reform" has led more people to pay attention to the environmental hygiene of public toilets, and the use of deodorants in public toilets is gradually increasing.

How are garbage deodorants generally used?

Each type of garbage deodorant is a concentrated solution of deodorant, which is generally mixed with water in proportion according to the requirements of the product manual. After mixing, it is used by direct spraying; Mechanical methods can also be used for large-scale spraying; Perhaps pipeline spraying should be chosen;

The requirements for deodorants in the specifications include the following:

The physiological targets mainly include acute oral toxicity and acute inhalation toxicity. Acute oral toxicity refers to the dosage of a drug administered orally and ingested into the body, resulting in animal toxicity until death, as well as the toxic reactions and symptoms. Acute inhalation toxicity refers to the harmful effects caused by experimental animals continuing to inhale a absorbable test sample for a short period of time (24 hours). Regarding performance requirements, there are different requirements for different types of deodorants:

We have established several detection methods for testing items together:

The regulation has established special rules for the detection of the deodorization effect of biological and plant-based deodorants. The detailed method is to quantitatively regulate the gas entering the impact bottle containing the deodorant, and after a period of time, detect the gas concentration. After comparing the concentration values of the inlet and outlet gases, calculate the heading power.
