VOCs治理即揮發(fā)性有機(jī)物治理，對于空間環(huán)境的安全、人體健康安全有著深遠(yuǎn)意義，尤其對于環(huán)境污染較嚴(yán)重的地區(qū)，揮發(fā)性有機(jī)物治理勢在必行。隨著我國對于兩型社會建設(shè)的逐漸加快，對諸多地理空間的環(huán)境指標(biāo)要求提升，對于各企業(yè)污染物排放嚴(yán)格限制；傳統(tǒng)的活性炭吸附回收已遠(yuǎn)遠(yuǎn)不能滿足治理要求，沸石轉(zhuǎn)輪吸附濃縮應(yīng)運(yùn)而生，那么它比活性炭VOCs治理好在哪里呢？

The treatment of volatile organic compounds (VOCs), also known as volatile organic compounds (VOCs), has profound significance for the safety of the spatial environment and human health, especially in areas with severe environmental pollution. The treatment of VOCs is imperative. With the gradual acceleration of China's construction of a two oriented society, the requirements for environmental indicators in many geographical spaces have been raised, and strict restrictions have been imposed on pollutant emissions from various enterprises; Traditional activated carbon adsorption and recovery can no longer meet the requirements of treatment, and zeolite rotary adsorption concentration has emerged. So, where is it better than activated carbon VOCs treatment?

不產(chǎn)生危廢

No hazardous waste generated

活性炭吸附是傳統(tǒng)VOCs治理的重要方式，但是活性炭在高溫下會自燃，因為脫附溫度必須控制在一定范圍內(nèi)，導(dǎo)致脫附不完全，長期下來就形成了含VOCs的危險廢棄物。這些危險廢棄物的處理逐漸成為環(huán)保領(lǐng)域新的難題。而沸石不可燃，脫附溫度可高達(dá)200度，脫附完全，不會形成危險廢棄物。

Activated carbon adsorption is an important method for traditional VOCs treatment, but activated carbon will self ignite at high temperatures because the desorption temperature must be controlled within a certain range, resulting in incomplete desorption and the formation of hazardous waste containing VOCs over the long term. The treatment of these hazardous wastes has gradually become a new challenge in the field of environmental protection. Zeolite is non combustible, with a desorption temperature of up to 200 degrees Celsius, complete desorption, and will not form hazardous waste.

運(yùn)行維護(hù)成本低

Low operating and maintenance costs

活性炭由于自身原因，脫附不完全，日積月累后，吸附能力下降，吸附容量飽滿后，必須更換，這就造成維護(hù)成本的上升。

Due to its own reasons, activated carbon is not completely desorbed, and over time, its adsorption capacity decreases. When the adsorption capacity is full, it must be replaced, resulting in an increase in maintenance costs.

污染物處理能力穩(wěn)定

Stable pollutant treatment capacity

活性炭因為脫附不完全，吸附容量越來越低，隨著吸附能力下降，對污染物的處理效率也隨著下降，因此在活性炭處理周期內(nèi)，處理能力越來越低。沸石由于脫附完全，吸附容量幾乎不變，對污染物處理能力較穩(wěn)定。

Due to incomplete desorption, the adsorption capacity of activated carbon decreases. As the adsorption capacity decreases, the efficiency of pollutant treatment also decreases. Therefore, during the activated carbon treatment cycle, the treatment capacity decreases. Zeolite has a relatively stable ability to treat pollutants due to its complete desorption and almost unchanged adsorption capacity.

使用壽命久

Long service life

普通的活性炭治理不但成本高，而且需要高頻度持續(xù)性投入，對于眾多企業(yè)來說投入過大；而沸石作為安全可靠的VOCs治理途徑，它的使用壽命長，它的物理和化學(xué)性質(zhì)佳，具有不可燃性；即便在高溫狀態(tài)下也不會產(chǎn)生自燃現(xiàn)象，壽命比同類產(chǎn)品高出多倍?？?-10年不更換。

Ordinary activated carbon treatment not only has high costs, but also requires high-frequency and continuous investment, which is too much investment for many enterprises; As a safe and reliable way to treat VOCs, zeolite has a long service life, excellent physical and chemical properties, and non flammability; Even at high temperatures, there will be no spontaneous combustion phenomenon, and the lifespan is many times longer than similar products. May not be replaced for 5-10 years.

通過以上介紹和對比可知：沸石在VOCs治理上較活性炭有一定優(yōu)勢，逐漸成為VOCs治理的主流產(chǎn)品，其應(yīng)用性強(qiáng)，應(yīng)用范圍廣，對于精細(xì)化工業(yè)、醫(yī)藥與農(nóng)藥制造業(yè)以及粘和劑生產(chǎn)、金屬及機(jī)械制造等行業(yè)均具有重要的意義。

Through the above introduction and comparison, it can be seen that zeolite has certain advantages over activated carbon in VOCs treatment and has gradually become the mainstream product of VOCs treatment. Its strong applicability and wide application range are of great significance for fine chemical industry, pharmaceutical and pesticide manufacturing, adhesive production, metal and machinery manufacturing, and other industries.
