Method for recovering phosphorous from activated sludge |
| abstract |
The present invention relates to a method for extracting phosphorus contained in sludge by a quick and efficient method using activated sludge of a wastewater bioreactor to be discarded, and recovering phosphorus to be used for raw materials such as fertilizer. To this end, an extraction step is firstly carried out to convert the phosphorus contained in the activated sludge into a form which is easily dissolved in water, and a separation step in which the extracted soluble phosphorus is mixed with other chemicals and precipitated and separated. Finally, In the form of sediment-like solids containing high or even higher phosphorus. |
