可能有些人還不知道什么是生物脫硫洗滌塔？下面我們就來詳細了解下什么是生物脫硫洗滌塔。生物脫硫洗滌塔的構(gòu)成主要有兩大方面：一是由一個裝有填料的洗滌器，二是一個具有活性污泥的生物反應器，主要由這兩大部件構(gòu)成。
Maybe some people don't know what is biological desulfurization scrubber? Let's learn more about the biological desulfurization scrubber. There are two parts in the structure of biological desulfurization scrubber: one is a scrubber with packing; the other is a bioreactor with activated sludge, which is mainly composed of these two parts.
由于生物堿性洗滌液的堿性特性，洗滌塔的材質(zhì)佳地選擇FRP，生物洗滌塔幾何尺寸規(guī)格范圍為800mm-1600mm，高度范圍10m-17m，根據(jù)脫硫效果設(shè)定，生物洗滌塔內(nèi)的填料一般按2層裝填；相關(guān)生物洗滌塔塔內(nèi)設(shè)施有內(nèi)部填充玻爾環(huán)填料、噴頭、洗滌管、填料支架、布水器、消泡噴淋裝置、除沫器等，確保良好的氣液接觸效果以及較好的運行穩(wěn)定性。輔助設(shè)施有：基礎(chǔ)和H鋼搭建的工作平臺（平臺一般可為3層），便于裝卸填料等。
Due to the alkaline characteristics of biological alkaline washing solution, the material of scrubbing tower is preferably FRP. The geometric size range of biological scrubber is 800mm-1600mm, and the height range is 10m-17m. According to the desulfurization effect, the packing in the biological scrubbing tower is generally packed in two layers; the relevant facilities in the biological scrubber include inner filling Bohr ring packing, nozzle, washing pipe, packing support and water distributor To ensure good gas-liquid contact effect and good operation stability. The auxiliary facilities include: the working platform built by foundation and H steel (the platform can be generally 3 layers), which is convenient for loading and unloading fillers.
在生物脫硫洗滌塔中的洗滌器，可以使廢氣中的污染物與填料表面的水有所接觸后被水吸收而轉(zhuǎn)入液相，當洗滌器吸收了廢氣組分的洗滌液,流入活性污泥池中,通入空氣充氧后再生,被吸收的氣態(tài)污染物通過微生物氧化作用,被活性污泥懸浮液從液相中除去,生物洗滌塔工藝中的液相是流動的,便于添加營養(yǎng)液、緩沖劑和更換液體,除去多余的產(chǎn)物。
The scrubber in the biological desulfurization scrubber can make the pollutants in the waste gas contact with the water on the surface of the filler, and then be absorbed by the water and transferred into the liquid phase. When the scrubber absorbs the washing liquid of the waste gas components, it flows into the activated sludge pool, and then it is regenerated after being aerated with air. The absorbed gaseous pollutants are removed from the liquid phase by the activated sludge suspension through microbial oxidation, The liquid phase in the biological scrubber process is mobile, which is convenient for adding nutrient solution, buffer and changing liquid to remove the surplus products.
不同成分、濃度及氣量的氣態(tài)污染物各有其有效的生物凈化系統(tǒng)。生物洗滌塔適宜于處理凈化氣量較小、濃度大、易溶且生物代謝速率較低的廢氣;對于氣量大、濃度低的廢氣可采用生物過濾床;而對于負荷較高以及污染物降解后會生成酸性物質(zhì)的則以生物滴濾床為好。
Different composition, concentration and gas volume of gaseous pollutants have their own effective biological purification system. The biological scrubbing tower is suitable for the treatment of the waste gas with small purification volume, high concentration, easy solubility and low biological metabolism rate; the biological filter bed can be used for the waste gas with large gas volume and low concentration; and the biotrickling filter bed is better for those with high load and acid substances generated after the degradation of pollutants.
在生物塔反應器內(nèi)設(shè)置填料，廢氣經(jīng)過充氧后與填料相接觸，在填料表面生物膜和填料空隙間的活性污泥雙重作用下，使廢氣得到凈化。生物塔內(nèi)裝有填料，大部分微生物以生物膜的形式固著生長于填料表面，少部分則以活性污泥的形式懸浮生長于水中。因此，生物塔兼有活性污泥法與生物過濾特性，是一種以生物膜法作用為主、兼有活性污泥法作用的生物處理工藝。
Packing is set in the bio tower reactor, and the waste gas contacts with the packing after being oxygenated. The waste gas is purified under the double action of the biofilm on the surface of the packing and the activated sludge between the packing space. Most of the microorganisms are fixed on the surface of the packing in the form of biofilm, while a few of them are suspended in the water in the form of activated sludge. Therefore, the biological tower has the characteristics of both activated sludge process and biological filtration. It is a biological treatment process with the main function of biofilm process and the role of activated sludge process.
