| Research Abstract |
A resin molding body carried with a hydrotalcite compound (HT) in large quantities was developed. Abilities of the HT molding body for adsorption, regeneration and phosphorus recovery were evaluated. As a result, the HT molding body made with cheap ethyl cellulose was able to carry for more than 90 % of HT by the weight ratio. The quantity of maximum phosphorus adsorption was 52.16 mg P・g-1, and desorbed phosphorus was able to recovery as hydroxyapatite (HAP) more than 95 %. The flowing through capacity of the HT molding body of the small particle diameter was 19.63 mg of P・g-1. It was thought that systems architecture to hold pH handling of raw water in check was necessary. The findings enable the establishment of the super advance phosphorus removal, recovery, the recycling system using a device of the existing practical scale.
