Method for treating VOCs-containing exhaust gas escaping from sewage treatment plant

The invention discloses a method for treating VOCs-containing exhaust gas escaping from a sewage treatment plant, and belongs to the field of purification of VOCs-containing exhaust gases. The treatment method comprises the following steps: high-concentration VOCs exhaust gas and low-concentration VOCs exhaust gas in the VOCs-containing exhaust gas escaping from the sewage treatment plant are separately collected; the high-concentration VOCs exhaust gas firstly enters a desulfurization section bed, undergoes dry desulfurization, then enters an adsorption bed, and undergoes adsorption purification to obtain an adsorbed clean gas; and the adsorbed clean gas is mixed with the low-concentration VOCs exhaust gas, and the obtained gas mixture is treated by a biological technology. The method inthe embodiment of the invention can simultaneously treat the high-concentration and low-concentration VOCs exhaust gases escaping from the sewage treatment plant, allows the purified gas to meet the relevant requirements of t
