Latest Patents

One of Fangzhai Zhang's latest patents is titled "Apparatus and method for synchronously treating sewage and sludge through combination of step-feed partial nitrification and anaerobic ammonia oxidation." This invention discloses an apparatus and method that effectively treats sewage and sludge using a step-feed partial nitrification process coupled with anaerobic ammonia oxidation. The process begins with ammonia-rich landfill leachate being pumped into an aerobic reactor for partial nitrification. The effluent from this reactor is then combined with exogenous surplus sludge in an anoxic reactor to achieve integrated fermentation and denitrification. The final effluent is processed in an integrated autotrophic nitrogen removal reactor, which operates stably and reliably, achieving efficient nitrogen removal without the need for external carbon sources.

Another significant patent by Zhang is the "Indoor grey water purification and reuse device, system and method for public buildings." This invention includes a grey water storage tank, a treatment assembly, and a pneumatic reclaimed water tank assembly. The system is designed to store and purify grey water collected from public buildings, ensuring that the treated water can be reused effectively. The multistage purification treatment enhances the quality of the grey water, making it suitable for various applications within the building.
