Abstract

The invention discloses a novel method for treating VOCs (Volatile Organic Compounds) waste gas of middle and small-sized enterprises. A specific process of the novel method provided by the invention comprises the following steps: (1) introducing generated organic waste gas into waste gas treatment devices by the middle and small-sized enterprises respectively according to the amount of 20000m<3> / h to 30000<3> / h and carrying out adsorption treatment; (2) connecting an exhausting end of the waste gas treatment device with a biological filter tower; directly carrying out filtering treatment on the waste gas subjected to the adsorption treatment through the biological filter tower; (3) establishing a common molecular sieve regeneration center at one site, and centralizing molecular sieves, which are adsorbed and saturated in the waste gas treatment devices of the middle and small-sized enterprises, to the common molecular sieve regeneration center, and carrying out desorption and regeneration on the recycled adsorbed and saturated molecular sieves through a heat accumulation type heat oxidization furnace of the molecular sieve regeneration center; meanwhile, carrying out complete oxidization and decomposition on the desorbed VOCs. A treatment technology provided by the invention can be combined with actual conditions of the middle and small-sized enterprises; the management efficiency on the VOCs is high, the cost is low and the available value is high.

Description

technical field [0001] The invention relates to the technical fields of atmospheric environmental pollution control, biological filtration and environmental pollution control, in particular to a method for treating volatile organic compound waste gas of small and medium-sized enterprises.
