%X In order to extract nitrogen and phosphorus from waste activated sludge(WAS) for enhancing its reclamation and reduction,three kinds of methods,alkaline thermal hydrolysis,ultrasonication and ultrasonic-alkali extraction,were used to treat WAS respectively.On the basis of optimizing the extraction conditions for each method,the extraction rate of inorganic nitrogen(IN) and phosphorus(PO3-4-P) and mass decrement of WAS were compared among three kinds of methods.The results showed that the optimum conditions ...
