Are there any regulatory documents that set requirements for the treatment of biological fermentation exhaust gases?

In terms of the treatment of biological fermentation waste gases, the \"Emission Standards for Air Pollutants in the Pharmaceutical Industry\" (GB 37823) is indeed a relevant standard. However, as you mentioned, it focuses mainly on chemical parameters and does not specify any requirements regarding bacterial viability. In addition, the specific regulations or standards regarding exhaust gas treatment during biological fermentation may not be very clear or straightforward. Generally speaking, biological fermentation off-gases mainly consist of organic volatile compounds (VOCs) and malodorous substances, and these usually need to be controlled in accordance with environmental protection regulations. If there is particular concern regarding the release of microbial cells, it may be necessary to combine research in environmental microbiology with actual process control in order to establish internal management standards or operating procedures that ensure compliance with environmental and safety requirements. You may consider consulting environmental protection agencies or professional organizations to see if there are any new regulations or recommendations applicable to your situation. .

If the detection method for bacterial viability is proposed, how is it done? In terms of processing efficiency, it’s sufficient to simply measure the inlet and outlet.
