  • Patent number: 11970415
    Abstract: The present invention discloses a sludge anaerobic fermentation treatment method with simultaneously enhanced acid production and phosphorus removal. The method includes steps of: (1) adding waste activated sludge into an anaerobic reaction system, with a concentration of a total suspended solid (TSS) of 10000-15000 mg/L; (2) maintaining a pH value of the waste activated sludge at 10±0.1; adding powdery magnetite of 0.3-0.9 g/gVS S. Compared with simple alkaline conditions, in the method of the present invention, an accumulation amount of short chain fatty acids (SCFAs) in a fermentation broth is increased by 20%, and a content of orthophosphoric acid is reduced by 10%. The method can further improve the enhancing effect by using sulfuric acid to modify the magnetite, the accumulation amount of SCFAs can be increased by 36.7% at most, and the content of phosphorus and refractory organic substances can be reduced by 32.4% and 40.4% at most, respectively.

  • Patent number: 11912595
    Abstract: The present invention relates to a groundwater circulation well system with pressure-adjustable hydrodynamic cavitation, including a circulation well body, a sucked and injected water circulation assembly and a hydrodynamic cavitator. The sucked and injected water circulation assembly is based on a water suction and injection pump. The hydrodynamic cavitator is provided, inside a vortex chamber, with a vortex water inlet column capable of changing a water passing aperture. The hydrodynamic cavitator is capable of changing a bubbling pressure and a breaking pressure of hydrodynamic cavitation bubbles in the vortex water inlet column. The hydrodynamic cavitator generates vortices in the circulation well body to accelerate uniform mixing of a remediation agent and the groundwater. Energy from collapsing and bursting of the hydrodynamic cavitation bubbles activates the remediation agent such that contaminants in the groundwater are efficiently degraded.
