在環(huán)保要求日益嚴(yán)苛的當(dāng)下，含硫廢氣、廢液的處理成為眾多工業(yè)領(lǐng)域的重要課題。生物脫硫塔作為生物脫硫技術(shù)的核心設(shè)備，憑借其綠色、高效的特性，在能源、化工、冶金等行業(yè)的脫硫環(huán)節(jié)中嶄露頭角。它以微生物的代謝活動為基礎(chǔ)，將含硫污染物轉(zhuǎn)化為無害物質(zhì)，為實現(xiàn)清潔生產(chǎn)和可持續(xù)發(fā)展提供了有力支撐。

In the increasingly stringent environmental requirements, the treatment of sulfur-containing waste gas and liquid has become an important issue in many industrial fields. As the core equipment of biological desulfurization technology, the biological desulfurization tower has emerged in the desulfurization process of energy, chemical, metallurgical and other industries due to its green and efficient characteristics. It is based on the metabolic activity of microorganisms, converting sulfur-containing pollutants into harmless substances, providing strong support for achieving clean production and sustainable development.

生物脫硫塔通常由塔體、填料層、布?xì)猓ㄒ海┭b置、噴淋系統(tǒng)、微生物培養(yǎng)系統(tǒng)和控制系統(tǒng)等部分組成。塔體一般采用圓柱形結(jié)構(gòu)，由耐腐蝕材料制成，如玻璃鋼、不銹鋼或特殊防腐涂層的碳鋼，以適應(yīng)含硫物質(zhì)的腐蝕環(huán)境。?

A biological desulfurization tower typically consists of a tower body, packing layer, gas (liquid) distribution device, spray system, microbial cultivation system, and control system. The tower body generally adopts a cylindrical structure and is made of corrosion-resistant materials, such as fiberglass, stainless steel, or carbon steel with special anti-corrosion coatings, to adapt to the corrosive environment of sulfur-containing substances. ?

填料層是生物脫硫塔的核心區(qū)域，它為微生物提供附著生長的表面。常用的填料有塑料花環(huán)填料、陶瓷填料、彈性立體填料等。這些填料具有比表面積大、孔隙率高、化學(xué)穩(wěn)定性好的特點，能夠增加微生物與含硫物質(zhì)的接觸面積，提高脫硫效率。例如，塑料花環(huán)填料結(jié)構(gòu)輕巧，不易堵塞，能有效促進(jìn)氣 - 液 - 固三相之間的傳質(zhì)與反應(yīng)。?

The packing layer is the core area of the biological desulfurization tower, providing a surface for microorganisms to attach and grow. Common fillers include plastic flower wreath fillers, ceramic fillers, elastic three-dimensional fillers, etc. These fillers have the characteristics of large specific surface area, high porosity, and good chemical stability, which can increase the contact area between microorganisms and sulfur-containing substances and improve desulfurization efficiency. For example, plastic flower garland fillers have a lightweight structure, are not easily clogged, and can effectively promote mass transfer and reaction between the gas liquid solid phases. ?

布?xì)猓ㄒ海┭b置位于塔體底部，其作用是使含硫廢氣或廢液均勻分布在填料層底部，確保與微生物充分接觸。對于廢氣處理的生物脫硫塔，布?xì)庋b置通過合理設(shè)計的氣孔或氣體分布器，將廢氣均勻分散；而處理廢液的脫硫塔，布液裝置則通過管道和噴頭，使廢液均勻噴淋在填料上。?

The gas (liquid) distribution device is located at the bottom of the tower, and its function is to evenly distribute sulfur-containing waste gas or liquid at the bottom of the packing layer, ensuring sufficient contact with microorganisms. For the biological desulfurization tower for waste gas treatment, the gas distribution device evenly disperses the waste gas through well-designed pores or gas distributors; The desulfurization tower for treating waste liquid and the liquid distribution device evenly spray the waste liquid onto the packing material through pipelines and nozzles. ?

噴淋系統(tǒng)用于向填料層噴灑營養(yǎng)液或洗滌液。營養(yǎng)液中含有微生物生長所需的碳源、氮源、磷源等營養(yǎng)物質(zhì)，維持微生物的活性；洗滌液則用于清洗填料表面，防止雜質(zhì)和代謝產(chǎn)物積累導(dǎo)致填料堵塞，影響傳質(zhì)效率。?

The sprinkler system is used to spray nutrient solution or washing solution onto the filling layer. The nutrient solution contains nutrients such as carbon, nitrogen, and phosphorus required for microbial growth, which maintain the activity of microorganisms; Washing solution is used to clean the surface of the packing material, preventing impurities and metabolites from accumulating and causing packing blockage, which affects mass transfer efficiency. ?

微生物培養(yǎng)系統(tǒng)負(fù)責(zé)培養(yǎng)和馴化高效脫硫微生物。該系統(tǒng)包括菌種儲存罐、培養(yǎng)基配制設(shè)備以及接種裝置等。通過篩選和培育適合特定含硫物質(zhì)處理的微生物菌種，并在塔內(nèi)創(chuàng)造適宜的生長環(huán)境，使微生物能夠快速繁殖并發(fā)揮脫硫作用。?

The microbial cultivation system is responsible for cultivating and domesticating efficient desulfurization microorganisms. The system includes strain storage tanks, culture medium preparation equipment, and inoculation devices. By screening and cultivating microbial strains suitable for specific sulfur-containing substance treatment, and creating a suitable growth environment inside the tower, microorganisms can rapidly reproduce and exert desulfurization effects. ?

控制系統(tǒng)則對生物脫硫塔的運行參數(shù)進(jìn)行實時監(jiān)測和調(diào)節(jié)，如溫度、pH 值、氣體流量、液體噴淋量等。通過傳感器采集數(shù)據(jù)，并將信息反饋給控制系統(tǒng)，一旦參數(shù)偏離設(shè)定范圍，系統(tǒng)會自動調(diào)節(jié)相關(guān)設(shè)備，確保脫硫塔穩(wěn)定運行。

The control system monitors and adjusts the operating parameters of the biological desulfurization tower in real-time, such as temperature, pH value, gas flow rate, liquid spray rate, etc. By collecting data through sensors and providing feedback to the control system, once the parameters deviate from the set range, the system will automatically adjust the relevant equipment to ensure the stable operation of the desulfurization tower.

未來，生物脫硫塔的發(fā)展將朝著高效化、智能化和集成化方向邁進(jìn)。通過基因工程、代謝工程等生物技術(shù)手段，培育更高效、更穩(wěn)定的脫硫微生物菌種；利用先進(jìn)的傳感器和控制技術(shù)，實現(xiàn)對脫硫塔運行參數(shù)的實時、精準(zhǔn)調(diào)控，提高設(shè)備的自動化水平；將生物脫硫塔與其他處理技術(shù)集成，形成聯(lián)合脫硫工藝，提高處理效率和適應(yīng)性，使其在更多領(lǐng)域得到廣泛應(yīng)用，為環(huán)境保護(hù)和可持續(xù)發(fā)展做出更大貢獻(xiàn)。?

In the future, the development of biological desulfurization towers will move towards high efficiency, intelligence, and integration. Cultivate more efficient and stable desulfurization microbial strains through biotechnology methods such as genetic engineering and metabolic engineering; By utilizing advanced sensors and control technology, real-time and precise control of the operating parameters of the desulfurization tower can be achieved, improving the automation level of the equipment; Integrating biological desulfurization towers with other treatment technologies to form a joint desulfurization process, improving treatment efficiency and adaptability, and enabling them to be widely applied in more fields, making greater contributions to environmental protection and sustainable development. ?
