可能有些人还不知道什么是生物脱硫洗涤塔？下面我们就来详细了解下什么是生物脱硫洗涤塔。生物脱硫洗涤塔的构成主要有两大方面：一是由一个装有填料的洗涤器，二是一个具有活性污泥的生物反应器，主要由这两大部件构成。
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.
由于生物碱性洗涤液的碱性特性，洗涤塔的材质佳地选择FRP，生物洗涤塔几何尺寸规格范围为800mm-1600mm，高度范围10m-17m，根据脱硫效果设定，生物洗涤塔内的填料一般按2层装填；相关生物洗涤塔塔内设施有内部填充玻尔环填料、喷头、洗涤管、填料支架、布水器、消泡喷淋装置、除沫器等，确保良好的气液接触效果以及较好的运行稳定性。辅助设施有：基础和H钢搭建的工作平台（平台一般可为3层），便于装卸填料等。
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.
在生物脱硫洗涤塔中的洗涤器，可以使废气中的污染物与填料表面的水有所接触后被水吸收而转入液相，当洗涤器吸收了废气组分的洗涤液,流入活性污泥池中,通入空气充氧后再生,被吸收的气态污染物通过微生物氧化作用,被活性污泥悬浮液从液相中除去,生物洗涤塔工艺中的液相是流动的,便于添加营养液、缓冲剂和更换液体,除去多余的产物。
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、浓度及气量的气态污染物各有其有效的生物净化系统。生物洗涤塔适宜于处理净化气量较小、浓度大、易溶且生物代谢速率较低的废气;对于气量大、浓度低的废气可采用生物过滤床;而对于负荷较高以及污染物降解后会生成酸性物质的则以生物滴滤床为好。
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.
在生物塔反应器内设置填料，废气经过充氧后与填料相接触，在填料表面生物膜和填料空隙间的活性污泥双重作用下，使废气得到净化。生物塔内装有填料，大部分微生物以生物膜的形式固着生长于填料表面，少部分则以活性污泥的形式悬浮生长于水中。因此，生物塔兼有活性污泥法与生物过滤特性，是一种以生物膜法作用为主、兼有活性污泥法作用的生物处理工艺。
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.
