Deodorization of leachate from garbage

Deodorization of leachate from garbageDeodorization mechanism

a. The odorous gas dissolves when it comes into contact with the water film on the surface of the filler (biological filler) that is moistened by the dispersed water.

b. The odorous components dissolved in water are absorbed and decomposed by microorganisms residing on the filling material (biological filling material).

c. The absorbed odorous components also become a source of nutrients for microorganisms, which are absorbed, oxidized, decomposed, and utilized.

The above three phenomena occur synchronously and continuously. Some odor molecules with poor solubility can be directly captured and degraded by microorganisms, resulting in higher removal rates.

Deodorization of leachate from garbageThe odorous substances that enter microbial cells are decomposed and converted into harmless and simple substances as energy and nutrients during microbial metabolism. Energy is generated during the conversion process, providing energy for the growth and reproduction of microorganisms in the filtration tower, ensuring the continuous conversion of waste odorous gas substances. Microorganisms exist in the form of populations, with multiple microorganisms coexisting in the same environment. The characteristics of microorganisms are both similar and different, and different pollutants can be degraded by microorganisms found in nature. Therefore, multiple pollutants can be treated and purified simultaneously in one device. Biological strains will cause pollutants to degrade into carbon dioxide and water, without producing secondary pollution.

Microorganisms use organic matter as the substrate for their growth and reproduction, and through different transformation pathways, they oxidize and decompose large molecules or structurally complex organic matter into simple inorganic substances such as water and carbon dioxide. At the same time, they assimilate and utilize the energy generated during the process of alienation to enable microbial organisms to grow and reproduce, creating favorable conditions for further enhancing their ability to handle organic matter.
