An oxygen supplying apparatus includes: an oxygen enriching module including a plurality of oxygen enriching units; a pressure boosting module which receives the oxygen-enriched gas from the oxygen enriching module and boosts pressure of the oxygen-enriched gas; and a controller controlling operations of the oxygen enriching module and the pressure boosting module. The pressure boosting module includes: a low-pressure tank which receives and stores the oxygen-enriched gas from the oxygen enriching module; a pressure booster which boosts pressure of the oxygen-enriched gas discharged from the low-pressure tank; a high-pressure tank stores the oxygen-enriched gas pressure-boosted by the pressure booster; and at least one bypass valve which is provided to a bypass passage for bypassing a portion of the pressure-boosted oxygen-enriched gas stored in the high-pressure tank to the low-pressure tank to regulate bypassing of the oxygen-enriched gas from the high-pressure tank to the low-pressure tank.

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 several steps as follow: 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. The treatment system in the present invention has the advantages of low processing cost, reduced malodor treatment volume, complete treatment of malodorous gas, and easy disposal of three wastes.
