6. Simple maintenance:? A small amount of maintenance work? (e.g. periodic calibration of pH probe)
The contact between waste gas and water or water film on solid surface is molecules or ions dissolved in water or liquid phase, that is, odor substances are transferred from gas phase to liquid phase, which is Henry's law of physical process.
The odor components in the aqueous solution are absorbed by microorganisms. Water is transferred from the water to microorganisms, and the water as an absorbent is regenerated and recycled, and then the new odorous components are dissolved.
The odor components entering the microbial cell body are divided into kinetic energy or nutrients of microbial life activities, so as to remove pollutants.
進到微生物胞體的物質(zhì)被胞體里的酶氧化和分化，合成產(chǎn)生新的微生物胞體。
Substances entering the microbial cell body are oxidized and differentiated by enzymes in the cell body to synthesize and produce new microbial cell bodies.
用雙膜生物膜理論解釋含硫廢氣的生物處理也有三個類似的步驟：
There are three similar steps to explain the biological treatment of sulfur-containing waste gas by using the double membrane biofilm Theory:
Sulfur containing gas contacts with water or the water film on the solid surface. The sulfur in the gas dissolves in water and becomes molecules or ions in the liquid phase. Sulfur is transferred from the gas phase to the liquid phase. This process is a physical process and follows Henry's law.
The sulfur in the aqueous solution diffuses into the biofilm and is absorbed by microorganisms under the promotion of concentration difference. Sulfur is converted from water to microorganisms as nutrition and energy for microorganisms.
