Latest Patents

Yuanji Shi holds a patent for a "System for cleaning wastewater." This system includes an absorption-biodegradation-denitrification (ABN) reactor, a sequential adsorption reactor, a disinfection reactor, and a sludge anaerobic fermentation reactor. The ABN reactor is an integrated unit that comprises a biosorption tank, an intermediate sedimentation tank, a biologically-enhanced degradation tank, a denitrification biofilter, and a secondary sedimentation tank. The pretreated wastewater is introduced into the ABN reactor for the removal of chemical oxygen demand, nitrogen, and phosphorus. The effluent from the ABN reactor is then processed through the sequential adsorption reactor to eliminate high-risk pollutants. Following this, the effluent is treated in the disinfection reactor to eliminate viruses and other pathogenic microorganisms. The sludge produced by the ABN reactor is directed into the anaerobic sludge fermentation reactor for alkaline fermentation. This innovative system is effective in removing high-risk pollutants and reducing effluent toxicity, making it suitable for upgrading and reconstructing wastewater treatment systems.
