摘要
PROBLEM TO BE SOLVED: To provide a phosphorus recovery material containing calcium and silicon that is low in production raw material cost, can be produced under a non-heating condition, has good reactivity with phosphorus in wastewater, and has good settleability of an aggregate formed by reacting with and absorbing phosphorus, and to provide a method for recovering phosphorus from wastewater using the phosphorus recovery material.;SOLUTION: We have found that after a phosphorus recovery material consisting of a composition containing an acid salt of calcium obtained by treating calcium other than a strong acid salt of calcium in an inexpensive calcium and silicon-containing composition with a strong acid under a non-heating condition, and having a molar ratio Ca/Si of 0.2-5.0 is reacted with phosphorus-containing wastewater, a phosphorus-absorbed product can be quickly precipitated.;COPYRIGHT: (C)2016,JPO&INPIT
