PROCESS AND PLANT FOR THE RECOVERY OF PHOSPHOROUS AND COAGULANTS FROM SLUDGE |
摘要 |
<p>A process for treatment of waste containing organic material, phosphorous and water in suitable amounts to be a pumpable sludge and in order to be oxidizable through supercritical water oxidation, comprises the steps of: putting the sludge into conditions being supercritical for water; adding oxidant, particularly, oxygen to the sludge, wherein the organic material contained in the waste is substantially completely oxidized by means of supercritical water oxidation; separating the phosphorous from water and from carbon dioxide formed during the oxidation; and recovering the phosphorous by means of dissolving the phosphorous in an alkali.</p> |
