生物除臭設備從字面意思上就可以知道是通過生物的方法進行除臭的一種除臭裝置，那么，從工藝的角度來說，這類生物除臭設備的原理是什么呢？

Biological deodorization equipment literally means a deodorizing device that uses biological methods for deodorization. So, from a technological perspective, what is the principle of this type of biological deodorization equipment?

一、生物濾池除臭設備概述

1、 Overview of Biological Filter Deodorization Equipment

生物濾池除臭設備：是以生物填料為載體，使微生物在適宜的環境下，在生物填料表面形成生物膜，生物膜中的微生物利用廢氣中的無機和有機物作為碳源和能源，通過降解惡臭物質維持其生命活動，并將惡臭物質分解成二氧化碳、水、礦物質等無臭物，達到凈化惡臭氣體的目的。

Biological filter deodorization equipment: It is a device that uses biological fillers as carriers to allow microorganisms to form biofilms on the surface of biological fillers in suitable environments. The microorganisms in the biofilm use inorganic and organic substances in exhaust gas as carbon sources and energy sources to maintain their life activities by degrading odorous substances, and decomposing odorous substances into odorless substances such as carbon dioxide, water, minerals, etc., achieving the goal of purifying odorous gases.

二、工藝流程

2、 Process flow

惡臭氣體收集裝置→預處理裝置→生物過濾裝置→抽風機→達標排放

Odor gas collection device → pretreatment device → biological filtration device → exhaust fan → standard emission

三、流程說明

3、 Process description

惡臭氣體經過管道收集后進入預處理裝置，經水洗加濕使廢氣的濕度達到90%以上，濕氣體再進入生物過濾除臭裝置，氣流與循環液在穿過生物填料層的過程中完成生物的氣液擴散、液固擴散、生物氧化三個過程，生物填料表面生物膜中的微生物以惡臭氣體物質為營養，惡臭物及VOCs被微生物氧化分解，在轉化過程中產生能量，為微生物的生長與繁殖提供能源，使惡臭氣體物質的轉化持續進行，經凈化后的氣體由引風機引出排放。

The odorous gas is collected through pipelines and enters the pre-treatment device. After being washed and humidified, the humidity of the exhaust gas reaches over 90%. The wet gas then enters the biological filtration and deodorization device. The airflow and circulating liquid complete three processes of biological gas-liquid diffusion, liquid-solid diffusion, and biological oxidation during the process of passing through the biological packing layer. The microorganisms in the biofilm on the surface of the biological packing take the odorous gas substances as nutrients, and the odorous substances and VOCs are oxidized and decomposed by the microorganisms. During the transformation process, energy is generated to provide energy for the growth and reproduction of microorganisms, so that the transformation of odorous gas substances continues. The purified gas is discharged from the induced draft fan.

循環液中含有脫落的生物膜和微生物，經過濾、補充新鮮洗滌液后循環使用，過濾去掉多余的少量生物膜作為污泥定期排放。

The circulating liquid contains detached biofilm and microorganisms, which are filtered and replenished with fresh washing solution before being recycled. The excess biofilm is removed by filtration and discharged regularly as sludge.

四、系統特點

4、 System features

1、 全自動控制，性能穩定，無須專人操作；

2、 使用長久性生物填料，微生物能夠依靠洗滌液中的養份和氣體中惡臭物質生長，無須另外投加營養劑。生物膜生態條件穩定，單位體積內生物量大，微生物菌群具有較高的生物吸附和生物氧化的能力，抗沖擊能力強，分解惡臭物質的速度快、效率高；

2. By using long-lasting biological fillers, microorganisms can grow by relying on nutrients in the washing solution and odorous substances in the gas, without the need to add additional nutrients. The ecological conditions of biofilm are stable, with a large biomass per unit volume. The microbial community has a high ability for biological adsorption and oxidation, strong shock resistance, and fast and efficient decomposition of odorous substances;

3、塔體采用模塊式結構，可現場施工，便于安裝；
