REVIEW ON EMISSION AND CONTROLLING MEASURES ON VOCs IN THE PROCESS OF ORGANIC WASTES BIOCONVERSION

Organic waste will produce large amount of VOCs in the biotransformation process， not only pollute the environment，endanger human health，but also become the bottleneck factor of current waste disposal engineering operation． In this article，literature reviewing is carried out to summarize the producing of organic waste VOCs，monitoring technologies， discharge status，influencing factors and controlling methods，in order to give references for controlling of the VOCs generated in organic waste bio-treatment． The results showed that，in the process of biotransformation of organic waste，there are more than 100 kinds of VOCs generated，and the concentration of VOCs produced in the landfill and composting are 67 to 7 896 mg / m3 and 411 to 14 547 mg /m3 ，respectively． The concentration of VOCs has a wide distribution range，and the removal efficiency is to be improved． The highest concentration of VOCs produced in anaerobic fermentation in general is no more than 30 mg /m3 ，which is easy to collect and remove through the catalytic and thermal incineration
