The activated carbon adsorption technology is a simple and easy treatment technology with low cost, and is a preferred treatment technology for small and medium-sized enterprises at present. However, the technology still has a plurality of problems, and the following problems are prominent in small and medium-sized enterprises: 1. the treatment cost is lowered, the condition of winning a bid at low price is very common, and the treatment facilities are difficult to realize standard discharge and stable operation; 2. the treatment facilities do not operate according to the standard, the operation materials (adsorbing materials, catalysts, heat accumulators and the like) are not replaced according to the specification, the treatment effect cannot be achieved in practice, even if treatment equipment is used, the treatment equipment only holds the treatment idea, and the treatment equipment is placed after the treatment equipment is checked and accepted for reducing the treatment cost. In industries such as spraying (such as spraying in 4S shops), printing (packaging and printing and book printing), chemical industry, pharmacy and the like, a large number of dispersed medium and small-sized VOCs emission enterprises exist, the emission amount of VOCs is small, the emission concentration is low, but the emission standard requirements which are gradually strict at present cannot be met, and the treatment of the enterprises is a difficult problem in the emission reduction and control work of VOCs at present.

Therefore, in recent years, various combined treatment technologies, such as adsorption concentration + catalytic combustion technology, adsorption concentration + high-temperature incineration technology, adsorption concentration + absorption technology, low-temperature plasma + catalytic technology, and the like, have been developed rapidly. The combined treatment technology is adopted, the pollutant discharge reaching the standard is realized from the aspect of purification effect, the treatment cost can be reduced from the aspect of cost, and the treatment effect is realized at the lowest cost. From the current treatment practice, the treatment of the VOCs in most industries needs to adopt a combination technology, and some industries even need to adopt more than two combination technologies to realize the treatment effect. However, the combined process has high one-time investment for small and medium-sized enterprises, low equipment utilization rate and easy generation of more secondary pollution.
