你知道嗎？我們?nèi)粘Ｉ钪惺褂玫挠推帷⒒瘖y品，甚至汽車尾氣，都在悄悄釋放一種看不見(jiàn)的 “隱形殺手”—— 揮發(fā)性有機(jī)化合物（VOCs）。這些物質(zhì)不僅威脅空氣質(zhì)量，更與每個(gè)人的健康息息相關(guān)。今天，讓我們揭開(kāi) VOCs 的神秘面紗，了解如何科學(xué)應(yīng)對(duì)這場(chǎng) “空氣保衛(wèi)戰(zhàn)”。

You know what? The paints, cosmetics, and even car exhaust we use in our daily lives are quietly releasing an invisible 'invisible killer' - volatile organic compounds (VOCs). These substances not only threaten air quality, but are also closely related to everyone's health. Today, let's unveil the mystery of VOCs and learn how to scientifically respond to this' air defense war '.

一、VOCs：看不見(jiàn)的健康威脅

1 VOCs： Invisible health threats

來(lái)源大起底

Source: Big Bottom

工業(yè)排放：石化、涂裝、印刷等行業(yè)每年排放數(shù)百萬(wàn)噸 VOCs，相當(dāng)于 2000 個(gè)西湖的水量。

Industrial emissions: The petrochemical, painting, printing and other industries emit millions of tons of VOCs annually, equivalent to the water volume of 2000 West Lake lakes.

生活場(chǎng)景：裝修涂料中的甲醛、干洗店的四氯乙烯、汽車尾氣中的苯系物，都是常見(jiàn)的 VOCs 來(lái)源。

Life scenario: Formaldehyde in decoration coatings, tetrachloroethylene in dry cleaners, and benzene derivatives in car exhaust are all common sources of VOCs.

自然釋放：森林中的萜烯類化合物也是天然 VOCs 的重要組成部分。

Natural release: Terpene compounds in forests are also an important component of natural VOCs.

健康警示燈

Health warning light

短期暴露：眼睛刺痛、喉嚨發(fā)炎、頭暈惡心（類似剛裝修完的房間感受）

Short term exposure: stinging eyes, sore throat, dizziness and nausea (similar to feeling in a newly renovated room)

長(zhǎng)期影響：增加白血病風(fēng)險(xiǎn)（如苯）、破壞臭氧層（如氟氯烴）、加劇溫室效應(yīng)

Long term effects: increased risk of leukemia (such as benzene), depletion of the ozone layer (such as hydrochlorofluorocarbons), exacerbation of greenhouse effect

二、科學(xué)應(yīng)對(duì)：四大核心處理技術(shù)

2、 Scientific Response: Four Core Processing Technologies

1. 吸附法：廢氣中的 “海綿”

1. Adsorption method: Sponge in exhaust gas

活性炭吸附：每克活性炭可吸附相當(dāng)于自身重量 20% 的 VOCs，常用于印刷廠廢氣處理

Activated carbon adsorption: Each gram of activated carbon can adsorb VOCs equivalent to 20% of its own weight, commonly used for printing factory exhaust gas treatment

沸石轉(zhuǎn)輪：日本某汽車廠案例顯示，沸石轉(zhuǎn)輪可將廢氣濃度濃縮 15 倍，配合 RTO 實(shí)現(xiàn) 99% 凈化率

Zeolite Wheel: A case study from a Japanese automobile factory shows that zeolite wheels can concentrate exhaust gas concentration by 15 times and achieve a 99% purification rate when combined with RTO

2. 燃燒法：高溫下的分解

2. Combustion method: decomposition at high temperature

直接燃燒：適用于高濃度廢氣（如石化廠火炬燃燒）

Direct combustion: suitable for high concentration exhaust gas (such as torch combustion in petrochemical plants)

催化燃燒：蜂窩狀催化劑使反應(yīng)溫度從 800℃降至 300℃，某家具廠應(yīng)用后節(jié)能 40%

Catalytic combustion: Honeycomb catalyst reduces reaction temperature from 800 ℃ to 300 ℃, saving 40% energy after application in a furniture factory

3. 冷凝回收：廢氣變資源

3. Condensation recovery: waste gas becomes a resource

某制藥廠通過(guò) - 70℃深冷技術(shù)，每年回收 200 噸甲苯，價(jià)值超 150 萬(wàn)元

A pharmaceutical factory uses -70 ℃ cryogenic technology to recover 200 tons of toluene annually, worth over 1.5 million yuan

常用于處理高沸點(diǎn)有機(jī)物（如二氯甲烷、DMF）

Commonly used for processing high boiling point organic compounds (such as dichloromethane, DMF)

4. 生物凈化：微生物的力量

4. Biological Purification: The Power of Microorganisms

德國(guó)某污水處理廠利用生物濾池，成功降解硫化氫等惡臭物質(zhì)

A sewage treatment plant in Germany successfully degraded odorous substances such as hydrogen sulfide using a biofilter

特別適合處理低濃度、易降解的 VOCs（如乙醇、乙酸乙酯）

Specially suitable for handling low concentration, easily degradable VOCs (such as ethanol, ethyl acetate)

三、行動(dòng)指南：我們能做什么？

3、 Action guide: What can we do?

企業(yè)篇

Enterprise section

安裝在線監(jiān)測(cè)系統(tǒng)，實(shí)時(shí)掌握排放數(shù)據(jù)（某省試點(diǎn)企業(yè)超標(biāo)率下降 65%）

Install an online monitoring system to obtain real-time emission data (a pilot enterprise in a certain province saw a 65% decrease in the over standard rate)

優(yōu)先選用低 VOCs 原輔材料（如水性涂料替代溶劑型涂料）

Prioritize the use of low VOC raw materials (such as water-based coatings instead of solvent based coatings)

公眾篇

Public article

裝修時(shí)選擇環(huán)保認(rèn)證產(chǎn)品（中國(guó)環(huán)境標(biāo)志認(rèn)證產(chǎn)品 VOCs 含量≤50mg/kg）

Choose environmentally certified products during decoration (VOCs content ≤ 50mg/kg for China Environmental Labeling certified products)

減少使用含 VOCs 的氣霧劑產(chǎn)品（改用泵壓式噴霧）

Reduce the use of aerosol products containing VOCs (use pump pressure spray instead)
