生物除臭設(shè)備濾池是一種利用微生物代謝活動(dòng)降解惡臭氣體的環(huán)保裝置，其核心在于通過構(gòu)建適宜的微生物生存環(huán)境，將硫化氫、氨氣、揮發(fā)性有機(jī)物等臭氣成分轉(zhuǎn)化為無害物質(zhì)。該技術(shù)以生態(tài)友好、運(yùn)行成本低、無二次污染等優(yōu)勢，廣泛應(yīng)用于垃圾處理、污水處理、畜牧養(yǎng)殖等領(lǐng)域。

　　Biological deodorization equipment filter is an environmentally friendly device that utilizes microbial metabolic activity to degrade odorous gases. Its core lies in creating a suitable microbial living environment to convert odorous components such as hydrogen sulfide, ammonia, and volatile organic compounds into harmless substances. This technology is widely used in fields such as garbage treatment, sewage treatment, and animal husbandry due to its advantages of ecological friendliness, low operating costs, and no secondary pollution.

　　濾池的工作流程可分解為三個(gè)關(guān)鍵階段：臭氣收集與傳輸、生物降解反應(yīng)、尾氣排放。首先，惡臭氣體通過密閉收集系統(tǒng)被導(dǎo)入濾池底部，經(jīng)由布?xì)庋b置均勻分散至填料層。這一步驟的設(shè)計(jì)至關(guān)重要，均勻的氣流分布能確保微生物與臭氣充分接觸，避免局部過載或處理盲區(qū)。

　　The workflow of the filter can be decomposed into three key stages: odor collection and transmission, biodegradation reaction, and exhaust emissions. Firstly, the odorous gas is introduced into the bottom of the filter through a closed collection system and evenly dispersed to the packing layer through a gas distribution device. The design of this step is crucial, as even airflow distribution can ensure sufficient contact between microorganisms and odors, avoiding local overload or blind spots in treatment.

　　填料層是濾池的核心反應(yīng)區(qū)，通常由多孔性惰性材料構(gòu)成，如陶粒、火山巖或復(fù)合有機(jī)載體。這些材料不僅為微生物提供附著表面，其孔隙結(jié)構(gòu)還能截留氣體中的顆粒物，并起到氣流均布作用。微生物群落以生物膜形式附著于填料表面，形成穩(wěn)定的生態(tài)系統(tǒng)。當(dāng)臭氣分子擴(kuò)散至生物膜時(shí)，特定菌種通過酶促反應(yīng)將其作為營養(yǎng)源分解。例如，硫化氫被硫氧化細(xì)菌轉(zhuǎn)化為硫酸鹽，氨氣經(jīng)硝化作用轉(zhuǎn)化為硝酸鹽，揮發(fā)性脂肪酸則被異養(yǎng)菌礦化為二氧化碳和水。

　　The packing layer is the core reaction zone of the filter tank, usually composed of porous inert materials such as ceramic particles, volcanic rocks, or composite organic carriers. These materials not only provide attachment surfaces for microorganisms, but their pore structure can also trap particles in the gas and achieve uniform airflow distribution. Microbial communities attach to the surface of fillers in the form of biofilms, forming a stable ecosystem. When odor molecules diffuse to the biofilm, specific bacterial species use enzymatic reactions to decompose them as a source of nutrients. For example, hydrogen sulfide is converted into sulfate by sulfur oxidizing bacteria, ammonia is converted into nitrate by nitrification, and volatile fatty acids are mineralized into carbon dioxide and water by heterotrophic bacteria.

　　生物降解過程的效率受環(huán)境參數(shù)影響顯著。溫度需控制在20-40℃之間，多數(shù)中溫微生物在此區(qū)間活性最佳；濕度需維持60%-90%，過干會(huì)導(dǎo)致微生物失活，過濕則引發(fā)填料板結(jié)；pH值需根據(jù)處理對象調(diào)整，如含硫臭氣處理需保持微堿性環(huán)境以促進(jìn)硫酸鹽生成。此外，營養(yǎng)物質(zhì)的均衡供給至關(guān)重要，當(dāng)臭氣中碳源不足時(shí)，需補(bǔ)充甲醇或葡萄糖等有機(jī)物，而氮磷缺乏則需添加尿素或磷酸鹽。

　　The efficiency of biodegradation process is significantly influenced by environmental parameters. The temperature should be controlled between 20-40 ℃, and most mesophilic microorganisms have the best activity in this range; The humidity should be maintained at 60% -90%. Excessive dryness can lead to microbial inactivation, while excessive humidity can cause packing compaction; The pH value needs to be adjusted according to the treatment object, such as maintaining a slightly alkaline environment for sulfur-containing odor treatment to promote sulfate generation. In addition, a balanced supply of nutrients is crucial. When the carbon source in the odor is insufficient, organic substances such as methanol or glucose need to be supplemented, while nitrogen and phosphorus deficiency requires the addition of urea or phosphate.

　　氣體在填料層中的停留時(shí)間直接影響處理效果，通常設(shè)計(jì)為15-60秒，需通過實(shí)驗(yàn)確定最佳空床停留時(shí)間。經(jīng)過生物降解后的氣體進(jìn)入濾池頂部的除霧層，去除夾帶的水分和微粒后排放。整個(gè)過程實(shí)現(xiàn)臭氣物質(zhì)的礦化，最終產(chǎn)物為無害的二氧化碳、水和無機(jī)鹽類。

　　The residence time of gas in the packing layer directly affects the treatment effect, usually designed to be 15-60 seconds, and the optimal empty bed residence time needs to be determined through experiments. After biodegradation, the gas enters the dehazing layer at the top of the filter tank to remove entrained moisture and particles before being discharged. The entire process realizes the mineralization of odorous substances, and the final products are harmless carbon dioxide, water, and inorganic salts.

　　生物除臭濾池的運(yùn)維重點(diǎn)包括填料定期更換、微生物群落監(jiān)測與補(bǔ)菌、環(huán)境參數(shù)動(dòng)態(tài)調(diào)控。隨著運(yùn)行時(shí)間延長，填料孔隙可能被無機(jī)鹽沉積物堵塞，需通過反沖洗或部分更換恢復(fù)通透性。同時(shí)，需定期檢測填料層微生物活性，當(dāng)處理效率下降時(shí)，需投加針對性菌劑以強(qiáng)化特定污染物的降解能力。

　　The key points of operation and maintenance of the biological deodorization filter include regular replacement of fillers, monitoring and supplementing of microbial communities, and dynamic regulation of environmental parameters. As the running time prolongs, the pores of the packing material may be blocked by inorganic salt deposits, and permeability needs to be restored through backwashing or partial replacement. At the same time, it is necessary to regularly test the microbial activity of the packing layer. When the treatment efficiency decreases, targeted microbial agents need to be added to enhance the degradation ability of specific pollutants.

　　該技術(shù)的創(chuàng)新方向集中于填料改良、菌種篩選與智能控制。新型復(fù)合填料通過添加活性炭或納米材料提升吸附容量，基因工程菌的應(yīng)用則可突破傳統(tǒng)微生物的處理極限。結(jié)合物聯(lián)網(wǎng)技術(shù)，實(shí)時(shí)監(jiān)測關(guān)鍵參數(shù)并自動(dòng)調(diào)節(jié)環(huán)境條件，已成為提升濾池穩(wěn)定性和處理效率的重要手段。

　　The innovation direction of this technology focuses on filler improvement, strain screening, and intelligent control. The new composite fillers can increase adsorption capacity by adding activated carbon or nanomaterials, and the application of genetically engineered bacteria can break through the processing limit of traditional microorganisms. Combining IoT technology, real-time monitoring of key parameters and automatic adjustment of environmental conditions has become an important means to improve the stability and treatment efficiency of filters.
