1, biological filtration deodorization
The deodorization technology of biological filter is to collect the odor generated during the operation of sewage station through a collection system, and then send it to subsequent treatment facilities after pressurization and humidification. Odor passes through the porous microbial layer, and microorganisms can absorb, adsorb and degrade the malodorous substances in the odor, decompose the malodorous substances into odorless and harmless inorganic substances, and discharge them into the atmosphere.
2, compound biological enzyme decomposition and deodorization
Because of its high efficiency, specificity, environmental protection and non-toxicity, it has been widely used in many industries and fields. With the development of the market and the increasing demand for products, compound biological enzyme has become the best choice to replace conventional chemical products in many fields.
How to deodorize the food in the refrigerator when it stinks?
1, grapefruit peel. Pomelo peel is an excellent deodorizer. It has a natural fruity taste. Because of its porous surface, it can absorb some odor similar to bamboo charcoal. Generally speaking, you only need to cut the grapefruit skin into small pieces and put it in the refrigerator for a few days, and the odor in the refrigerator will disappear, and it will also give off a fresh and natural grapefruit fragrance.
2. Wet lemon slices. Lemon is also a good helper to absorb the odor of refrigerator. First, the fresh aroma of lemon can properly cover up some unpleasant smells. Secondly, some smells are emitted by weakly basic amines. If lemon is acidic, the two will neutralize and become odorless ammonium salt to remove odor.
