VOCs治理即挥发性有机物治理，对于空间环境的安全、人体健康安全有着深远意义，尤其对于环境污染较严重的地区，挥发性有机物治理势在必行。随着我国对于两型社会建设的逐渐加快，对诸多地理空间的环境指标要求提升，对于各企业污染物排放严格限制；传统的活性炭吸附回收已远远不能满足治理要求，沸石转轮吸附浓缩应运而生，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?

不产生危废

No hazardous waste generated

活性炭吸附是传统VOCs治理的重要方式，但是活性炭在高温下会自燃，因为脱附温度必须控制在一定范围内，导致脱附不完全，长期下来就形成了含VOCs的危险废弃物。这些危险废弃物的处理逐渐成为环保领域新的难题。而沸石不可燃，脱附温度可高达200度，脱附完全，不会形成危险废弃物。

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.

运行维护成本低

Low operating and maintenance costs

活性炭由于自身原因，脱附不完全，日积月累后，吸附能力下降，吸附容量饱满后，必须更换，这就造成维护成本的上升。

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.

污染物处理能力稳定

Stable pollutant treatment capacity

活性炭因为脱附不完全，吸附容量越来越低，随着吸附能力下降，对污染物的处理效率也随着下降，因此在活性炭处理周期内，处理能力越来越低。沸石由于脱附完全，吸附容量几乎不变，对污染物处理能力较稳定。

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.

使用寿命久

Long service life

普通的活性炭治理不但成本高，而且需要高频度持续性投入，对于众多企业来说投入过大；而沸石作为安全可靠的VOCs治理途径，它的使用寿命长，它的物理和化学性质佳，具有不可燃性；即便在高温状态下也不会产生自燃现象，寿命比同类产品高出多倍。可5-10年不更换。

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.

通过以上介绍和对比可知：沸石在VOCs治理上较活性炭有一定优势，逐渐成为VOCs治理的主流产品，其应用性强，应用范围广，对于精细化工业、医药与农药制造业以及粘和剂生产、金属及机械制造等行业均具有重要的意义。

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.
