AI Technical Summary
Existing technologies are insufficient to effectively increase the upper limit of phosphate enrichment solution concentration and shorten the harvesting cycle in biofilm processes, resulting in high operating costs and failure to meet carbon emission reduction requirements.
By alternating between normal operation phases and multiple rounds of enhanced anaerobic phosphorus release treatment using carbon sources, the biofilm thickness and anaerobic influent pH are regulated. Combined with a gradual reduction in carbon source levels over multiple rounds, the phosphorus uptake and release behavior of PAOs cells and EPS is enhanced.
This approach achieves increased phosphate enrichment solution concentration and shortened harvesting cycle, reducing process operating costs while maintaining efficient biofilm operation.
