Abstract

<p>In order to recover the phosphorus from sewage sludge, some kinds of extraction methods using acid or alkali are investigated. Recovery rate of the phosphorus differ by the method applied for them. We compared the phosphorus recovery rate by some kinds of methods (①acid treatment,②alkali treatment, ③alkali heat treatment in 750℃, ④hydrothermal method) using same sludge. The acid treatment showed highest recovery rate, and alkali treatment have low recovery rate, however, recovery rate increased by the application of heat treatment or hydrothermal method, and aluminum contents in the recovered phosphorus became degreased.</p>
