Abstract

The present application provides a system for treating malodorous gas from sludge, which includes an air compressor, a first pressure swing adsorption tower, a second pressure swing adsorption tower, a buffer tank, a decomposition tank, an exhaust gas scrubber and a vacuum device. The present invention relates to a process for treating malodorous gas from sludge treatment, which includes: compressing the malodorous gas by using an air compressor, and adsorbing by using a pressure swing adsorbent. The air for removing the malodorous component is configured for sludge separation and aerobic aeration in the treatment tank. When the pressure swing adsorbent reaches the design upper limit value, the intake air is stopped, decompression and desorption start, and the enriched malodorous component is sent to catalytic combustion or photocatalytic decomposition, and then the acid gas in the tail gas is neutralized with an alkaline absorbent, and finally discharged to the standard.
