據悉,生物脫硫手藝包含生物過濾、生物吸擁護滴濾。這三個體系是開放體系,它們的微生物種群隨情況的變更而變更。
It is reported that biological desulfurization technology includes biofiltration, biosorption and trickle filtration. These three systems are open systems, and their microbial populations vary with the environment.
特色:
characteristic:
1、效力高:硫化氫清算率達98.5%。
1. High efficiency: the removal rate of hydrogen sulfide is 98.5%.
2、高順應規模:可處置硫化氫濃度達1.5%(15000ppm)。
2. High adaptability: it can process 1.5% (15000ppm) hydrogen sulfide.
3、本錢低:與別的脫硫手藝比擬,運轉本錢較低。
3. Low cost: compared with other desulfurization skills, the operation cost is lower.
4、高安然性:設有多種掩護裝配。
4. High safety: with a variety of protective devices.
5、無人值守:體系經由進程在線監測體系全主動運轉。
5. Unattended: the system runs automatically through online monitoring system.
6、保護簡略:少許的保護任務(如按期校訂PH探頭)。
6. Simple maintenance: a small amount of maintenance work (such as regular calibration of pH probe).
生物脫硫的三個步驟:
There are three steps in biological desulfurization
1、消融:
1. Dissolution:
廢氣與水或固體外表水膜的打仗是溶于水或液相的份子或離子,即惡臭物資從氣相轉移到液相,這一步便是亨利物理進程定律。
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, the transfer of malodorous substances from gas phase to liquid phase. This step is Henry's law of physical process.
             生物脫硫
2、吸擁護接收:
2. Adsorption and absorption:
水溶液中的惡臭成份被微生物接收。水從水直達移到微生物中,作為接收劑的水被復活和收受接管,而后新的有氣息的成份被消融。
The odor components in the aqueous solution are absorbed by microorganisms. The water is transferred from the water to the microorganism, the water as absorbent is regenerated and recycled, and then the new odorous components are dissolved.
3、生物降解:
3. Biodegradation:
進到微生物胞體的氣息成份被辨別為微生物性命勾當的動能或養分物資,從而清算污染物。
The odor components entering the microbial cell body are divided into kinetic energy or nutrients of microbial life activities, so as to clean up the pollutants.
進到微生物胞體的物資被胞體里的酶氧化和分解,分解發生新的微生物胞體。
The substances entering into the cell body of microorganism are oxidized and differentiated by enzymes in the cell body to produce new microbial cell bodies.
用雙膜生物膜實際詮釋含硫廢氣的生物處置也有三個近似的步驟:
There are three similar steps to explain the biological treatment of sulfur-containing waste gas with the theory of double membrane biofilm
含硫氣與水或固體外表的水膜打仗,氣體中的硫溶于水,在液相中變成份子或離子。硫從氣相轉移到液相。這個進程是一個物理進程,遵守亨利定律。
Sulfur gas contacts with water or water film on solid surface. Sulfur in gas dissolves in water and becomes molecule or ion in liquid phase. Sulfur is transferred from the gas phase to the liquid phase. This process is a physical process, following Henry's law.
生物脫硫時,水溶液中的硫在濃度差的鞭策下分散到生物膜中,被微生物接收。硫由水轉化為微生物,作為微生物的養分和能量。
In the process of biological desulfurization, the sulfur in the aqueous solution diffuses into the biofilm and is absorbed by microorganisms. Sulfur is transformed from water to microorganism, which is used as nutrition and energy of microorganism.
