Tenax—TA 吸附管测定制药工业大气污染物TVOC

对于无组织排放，其控制措施首先是源头替代、加强设备密闭密封、以及将无组织集气变为有组织。目前的不少企业已经开展此项工作，但在无组织废气收集方面往往存在问题，比如很多污水处理厂废气的收集系统设计并不合理，管道布置过于曲折，容易造成风压、风量不匹配不平衡，不仅存在泄露隐患，还容易造成过度稀释。因此，在集气系统设计以及材质选择上需要尤为注意。

对于有组织排放的处理技术，主要可分为有回收价值的高浓度废气和无回收价值的有机废气两大类。对于有回收价值的高浓度废气主要采取冷凝、吸附等技术进行回收，企业在这些技术的选择上主要考虑的是经济问题。对于无回收价值的有机废气主要采取蓄热式热力焚烧技术（RTO）、生物净化技术、低温等离子体技术、光催化技术（紫外光氧化）、借用其他热工设备焚烧、多种技术组合等进行处理，这几种技术都各有优缺点，需要综合技术的适用范围、控制要求、投资成本等多方面比较进行选取。

总的来说制药行业的VOCs废气治理的情况非常复杂，如何经济、合理地选取实用的处理技术还需要有针对性地开展“一厂一策”研究。

Filling: 200mg
Application: Determination of the air pollutant emission standard TVOC for the pharmaceutical industry

In order to meet the relevant standards and policy requirements of the pharmaceutical industry, VOCs control technology and measures must be adopted. But for pharmaceuticals, the control of VOCs has always been one of the key and difficult points. The pharmaceutical industry has many types of pollutants and complex components, and many of the emissions in the pharmaceutical industry are unstable and discontinuous, and the frequency of equipment startup and shutdown is relatively high. In addition, some pharmaceutical companies have a prominent problem of odor nuisance to the people. In order to meet the "nose standards" of the surrounding people, companies must meet higher emission requirements and must also assume more social responsibilities.

For fugitive emissions, its control measures are first to replace the source, strengthen the airtightness of the equipment, and change the unorganized gas collection into an organized. Many companies have already carried out this work, but there are often problems in unorganized waste gas collection. For example, the design of waste gas collection systems in many sewage treatment plants is unreasonable. Balance, not only has the hidden danger of leakage, but also easily causes excessive dilution. Therefore, special attention should be paid to the design of the gas gathering system and the selection of materials.

Regarding the treatment technology of organized emissions, it can be divided into two categories: high-concentration waste gas with recycling value and organic waste gas without recycling value. For high-concentration waste gas with recycling value, condensation, adsorption and other technologies are mainly used for recycling. The main consideration for enterprises in the selection of these technologies is economic issues. For organic waste gas with no recovery value, it mainly adopts regenerative thermal incineration technology (RTO), biological purification technology, low temperature plasma technology, photocatalysis technology (ultraviolet photooxidation), borrowing other thermal equipment for incineration, and multiple technology combinations. To deal with, these several technologies have their own advantages and disadvantages, and they need to be compared and selected in many aspects, such as the scope of application, control requirements, and investment costs of the comprehensive technology.

Generally speaking, the situation of VOCs waste gas treatment in the pharmaceutical industry is very complicated. How to economically and reasonably select practical treatment technologies also requires targeted research on "one plant, one policy".
