The invention provides a VOCs biological treatment process, and relates to the technical field of waste gas treatment, the adopted technical scheme includes that the VOCs biological treatment process comprises the following steps: S1, collecting VOCs waste gas discharged from an open-air tank body, S2, pre-wetting the VOCs waste gas in a spray tower, conveying the VOCs waste gas to a steam-water separator for water-gas separation, and S3, conveying the separated gas to a biological treatment tower, treating the gas through a biological filler layer, and discharging the treated gas at high altitude through a chimney. According to the invention, the compatibility of the filler and microorganisms is effectively improved, the growth of various microorganisms is facilitated, re-operation and re-starting are easy, good load fluctuation resistance and moisture retention performance are achieved, wind resistance is reduced, and long-term stable operation can be realized. 一种VOCs生物处理工艺，涉及废气处理技术领域，所采用的技术方案包括S1收集露天池体中排放的
