一种通过富集培养聚糖菌强化生物膜进行除磷及磷回收的方法
By adding AHLs and adjusting the process operating conditions during the biofilm formation stage, the polysaccharide bacterium Candidatus Competibacter was promoted to adhere to the biofilm and secrete EPS, which solved the problems of long enrichment time and low efficiency in the existing technology and achieved rapid and efficient phosphorus removal and recovery.

AI Technical Summary
Existing methods for enriching and culturing polysaccharide bacteria are time-consuming and cumbersome, failing to effectively enhance the phosphorus removal and recovery capabilities of biofilms, especially the secretory capacity of the polysaccharide bacterium Candidatus Competibacter, which is not fully utilized.
By adding N-acyl homoserine lactones (AHLs) and high concentrations of phosphate during the biofilm formation stage, the adhesion and growth of polysaccharide bacteria Candidatus Competibacter were promoted. After sludge removal, the process operation mode was adjusted to stimulate the secretion of EPS and AHLs. Combined with appropriate carbon source concentration and dissolved oxygen control, rapid enrichment culture was achieved.
It shortens the enrichment culture time, improves the phosphorus removal efficiency and phosphorus recovery capacity of biofilm, reduces costs, and achieves low-carbon and high-efficiency phosphorus recovery.
