Phosphorus collection proof examination from various sewage sludge incineration ashes by the waste alkali use

Abstract

The phosphorus collection proof examination was done by using the medicine alkali liquid and the waste alkali from the sewage sludge incineration ash generated in the Iwate prefecture and the Kansai district by the ash alkali extraction method. As a result, it has been understood to be able to collect phosphorus enough even if phosphorus can be collected without inferiority compared with the case to use the medicine alkali liquid when the waste alkali is used, and the mode of processing of the sewage plant is different.
