[0003] The swirling process of sewage can stretch the chemical molecules in the sewage and dissolve the compressed gas. The swirling process can also enhance the capture of oil droplets and particulate matter by the chemical molecules.

[0004] The common methods for treating wastewater and waste gas in China are to remove wastewater and waste gas by mixing wastewater with special gases or mixing waste gas with special liquids.
