%X Excess activated sludge can yield volatile fatty acid (VFAs) with high concentration after hydrolysis and acidification. Both acetate and propionate in VFAs are the most suitable carbon substrates for enhanced biological phosphorus removal (EBPR), but there is large amount of phosphorus in the centrifugate of acidified excess activated sludge. Without phosphorus removal, it would increase the loading of the wastewater treatment plant when it recycles to the front of the plant as carbon substrate. Phosphorus can be removed by struvite formation. This paper investigated the influence factors of phosphorus removal from centrifugate of acidified excess activated sludge. The result showed that the removal rates of ortho-phosphorus and total phosphorus were 92.5% and 83.8%, respectively, under the optimal conditions.
