Latest Patents
One of Xiaoli Chai's latest patents is titled "Organic composite powder carrier and application thereof in enhanced biological denitrification of municipal wastewater treatment." This invention relates to microbial carriers specifically designed for wastewater treatment. The organic composite powder carrier is composed of a microbial carrier with a relatively large equivalent particle size and an organic alternative carbon source in the form of ultrafine powder. This composite carrier includes a dedicated organic alternative carbon source, such as polyhydroxyalkanoates (PHA), which helps eliminate competition among microorganisms, ensuring that denitrifying bacteria receive the necessary electron donors for effective denitrification. This innovation significantly improves denitrification efficiency, enabling deep biological purification of wastewater and ensuring compliance with stringent domestic discharge standards.
Another notable patent is the "Recovery system of composite powder carrier in HPB municipal wastewater treatment." This system includes a biochemical tank and a concentration tank where the composite powder carrier is utilized for biochemically treating wastewater. The process involves filtering the mixed liquid to separate supernatant and concentrated sludge, with the latter being recycled for reuse. This innovative separator enhances the utilization rate of composite powder carriers and reduces operational costs associated with HPB technology in wastewater treatment.
