在工業(yè)生產、市政處理與農業(yè)養(yǎng)殖等領域，惡臭氣體治理已成為環(huán)境管理的核心課題。傳統(tǒng)除臭技術常面臨效率局限、二次污染或成本高企等，而生物除臭設備憑借“以菌治味”的天然邏輯，正成為多場景氣味管控的創(chuàng)新解決方案。

　　In the fields of industrial production, municipal treatment, and agricultural breeding, the treatment of odorous gases has become a core issue in environmental management. Traditional deodorization techniques often face efficiency limitations, secondary pollution, or high costs, while biological deodorization equipment, relying on the natural logic of "treating odors with bacteria", is becoming an innovative solution for odor control in multiple scenarios.

　　惡臭治理的技術演進：從物理遮蔽到生物降解

　　Technological evolution of odor control: from physical masking to biodegradation

　　傳統(tǒng)除臭手段多依賴物理吸附或化學中和?；钚蕴课椒ㄐ桀l繁更換耗材，且對低濃度臭氣效果有限；化學噴淋雖能快速反應，但可能產生含鹽廢水或次生污染物。生物除臭技術則另辟蹊徑，通過微生物代謝活動將硫化氫、氨氣、揮發(fā)性有機物（VOCs）等惡臭成分轉化為無害物質，實現(xiàn)源頭治理與生態(tài)閉環(huán)的雙重突破。

　　Traditional deodorization methods often rely on physical adsorption or chemical neutralization. The activated carbon adsorption method requires frequent replacement of consumables and has limited effectiveness on low concentration odors; Although chemical spraying can react quickly, it may produce saline wastewater or secondary pollutants. Biological deodorization technology takes a different approach by converting odorous components such as hydrogen sulfide, ammonia, and volatile organic compounds (VOCs) into harmless substances through microbial metabolic activity, achieving a dual breakthrough in source control and ecological closed-loop.

　　生物除臭設備的核心機理：三重技術路徑解析

　　The core mechanism of biological deodorization equipment: analysis of the triple technical path

　　生物過濾工藝

　　Biological filtration process

　　設備以天然或人工合成填料為載體，構建微生物附著床層。惡臭氣體經加濕后進入填料層，硫桿菌、硝化桿菌等專性菌群通過酶促反應，將硫化氫氧化為硫酸根，氨氣轉化為硝酸鹽。該工藝適用于處理低濃度、大氣量的連續(xù)排放場景，如污水處理廠曝氣池周邊空氣凈化。

　　The equipment uses natural or synthetic fillers as carriers to construct a microbial attachment bed. The odorous gas enters the packing layer after humidification, and specialized bacterial groups such as sulfur bacteria and nitrifying bacteria undergo enzymatic reactions to oxidize hydrogen sulfide into sulfate ions and convert ammonia into nitrate. This process is suitable for treating continuous discharge scenarios with low concentration and atmospheric volume, such as air purification around aeration tanks in sewage treatment plants.

　　生物洗滌工藝

　　Biological washing process

　　采用循環(huán)液噴淋與生物反應器組合設計。惡臭氣體與含有微生物的營養(yǎng)液充分接觸，污染物被吸收并進入液相代謝。此方案對水溶性好的物質（如乙酸乙酯）處理效率高，常見于食品加工廢氣治理，可通過調節(jié)pH值與營養(yǎng)配比優(yōu)化菌群活性。

　　Adopting a combination design of circulating liquid spray and bioreactor. Odorous gases come into full contact with nutrient solutions containing microorganisms, and pollutants are absorbed and enter the liquid phase for metabolism. This scheme has high treatment efficiency for water-soluble substances such as ethyl acetate, which is commonly used in the treatment of food processing waste gas. The microbial activity can be optimized by adjusting the pH value and nutrient ratio.

　　生物滴濾工藝

　　Biological drip filtration process

　　結合過濾與洗滌優(yōu)勢，填料層保持濕潤但不浸沒。氣體自下而上穿過填料，微生物以生物膜形式附著，代謝產物隨少量循環(huán)液排出。該工藝抗負荷沖擊能力強，在垃圾壓縮站、畜禽養(yǎng)殖場等臭氣濃度波動大的場景中表現(xiàn)穩(wěn)定。

　　Combining the advantages of filtration and washing, the packing layer remains moist but not submerged. Gas passes through the packing from bottom to top, microorganisms attach in the form of biofilms, and metabolic products are discharged with a small amount of circulating fluid. This process has strong resistance to load impact and performs stably in scenarios with large fluctuations in odor concentration, such as garbage compression stations and livestock farms.

　　定制化設計的關鍵維度：從菌種到結構的精準適配

　　The key dimension of customized design: precise adaptation from bacterial strains to structures

　　菌種庫構建

　　Construction of strain library

　　針對不同臭氣成分，需篩選高效降解菌株。例如，處理制藥廢氣中的甲硫醇需引入假單胞菌屬，而處理餐廚垃圾的胺類物質則需優(yōu)化芽孢桿菌組合。部分設備采用復合菌劑，通過馴化培養(yǎng)形成共生菌群，提升對復雜成分的降解能力。

　　Efficient degradation strains need to be screened for different odor components. For example, the treatment of methyl mercaptan in pharmaceutical waste gas requires the introduction of Pseudomonas species, while the treatment of amine substances in kitchen waste requires the optimization of spore bacteria combinations. Some devices use composite microbial agents to form symbiotic bacterial communities through domestication and cultivation, enhancing their ability to degrade complex components.

　　填料介質優(yōu)化

　　Optimization of packing medium

　　填料比表面積、孔隙率與親水性直接影響微生物附著效率。陶粒、火山巖等天然介質成本低廉，但需定期更換；聚氨酯泡沫、活性炭纖維等合成材料則可通過改性處理增強掛膜性能。模塊化設計使設備能根據(jù)工況調整填料配比。

　　The specific surface area, porosity, and hydrophilicity of fillers directly affect the efficiency of microbial attachment. Natural media such as ceramic particles and volcanic rocks have low costs, but need to be replaced regularly; Synthetic materials such as polyurethane foam and activated carbon fiber can be modified to enhance the film performance. Modular design enables the equipment to adjust the packing ratio according to operating conditions.

　　氣液傳質強化

　　Enhanced gas-liquid mass transfer

　　通過流體力學模擬優(yōu)化氣體分布器結構，避免短路流與死區(qū)。在噴淋系統(tǒng)中采用螺旋噴嘴或霧化盤，可提升液滴粒徑均勻性，增加氣液接觸面積。某型設備實測顯示，優(yōu)化后傳質效率提升，惡臭去除率顯著提高。

　　Optimize the structure of gas distributor through fluid dynamics simulation to avoid short-circuit flow and dead zone. The use of spiral nozzles or atomizing discs in sprinkler systems can improve the uniformity of droplet size and increase the gas-liquid contact area. The actual measurement of a certain type of equipment shows that after optimization, the mass transfer efficiency is improved and the odor removal rate is significantly increased.

　　場景化應用實踐：破解行業(yè)痛點

　　Scenario based application practice: cracking industry pain points

　　市政領域：在垃圾轉運站，設備通過生物過濾工藝將臭氣濃度降低，滿足《惡臭污染物排放標準》限值要求，同時避免化學藥劑對操作人員的健康風險。

　　In the municipal field: At the garbage transfer station, the equipment reduces the concentration of odor through biological filtration process, meeting the limit requirements of the "Odor Pollutant Emission Standards", while avoiding the health risks of chemical agents to operators.

　　工業(yè)領域：針對化工園區(qū)廢氣中的苯系物，生物洗滌設備通過定制化營養(yǎng)液配方，實現(xiàn)特定污染物的靶向降解，處理成本較傳統(tǒng)方法降低。

　　In the industrial field, for the benzene derivatives in the waste gas of chemical industrial parks, biological washing equipment achieves targeted degradation of specific pollutants through customized nutrient solution formulations, reducing treatment costs compared to traditional methods.

　　農業(yè)領域：在規(guī)模化養(yǎng)殖場，生物滴濾塔與舍內負壓系統(tǒng)聯(lián)動，將氨氣排放濃度控制在安全閾值以下，同時減少畜禽呼吸道疾病發(fā)生率。

　　In the field of agriculture, in large-scale breeding farms, the biological drip filtration tower is linked with the negative pressure system inside the house to control the concentration of ammonia emissions below the safe threshold, while reducing the incidence of respiratory diseases in livestock and poultry.

　　技術優(yōu)勢與實施要點

　　Technical advantages and implementation points

　　相比物理化學方法，生物除臭設備具有運行成本低、無二次污染、長期穩(wěn)定性好等優(yōu)勢。但需注意，設備啟動初期需2-4周完成菌群馴化，且對溫度、濕度、pH值等參數(shù)敏感。通過智能控制系統(tǒng)實時監(jiān)測填料層濕度、營養(yǎng)液濃度等指標，可保障設備始終處于最佳工況。

　　Compared to physical and chemical methods, biological deodorization equipment has advantages such as low operating costs, no secondary pollution, and good long-term stability. However, it should be noted that the initial start-up of the equipment requires 2-4 weeks to complete the domestication of the microbial community, and is sensitive to parameters such as temperature, humidity, and pH. Real time monitoring of indicators such as humidity and nutrient concentration in the packing layer through an intelligent control system can ensure that the equipment is always in optimal working condition.

　　生物除臭技術以自然循環(huán)為底層邏輯，通過微生物代謝活動將氣味污染轉化為生態(tài)資源。在環(huán)保標準趨嚴的背景下，這種“以菌治味”的解決方案正為工業(yè)與市政領域提供可持續(xù)的氣味管控路徑。

　　Biological deodorization technology takes natural circulation as its underlying logic and converts odor pollution into ecological resources through microbial metabolic activities. Against the backdrop of increasingly stringent environmental standards, this "using bacteria to treat odors" solution is providing a sustainable odor control path for the industrial and municipal sectors.
