PHOSPHORUS ADSORBENT, AND METHOD FOR REMOVING PHOSPHORUS IN NATURAL ENVIRONMENTAL WATER AREA

摘要

PROBLEM TO BE SOLVED: To provide a phosphorus adsorbent high in phosphorus adsorbing rate and continuing long in durabity without being clogged by turbid matter even if the quantity of the turbid matter of rivers increases, and to provide a rational phosphorus removing method easy installation. ;SOLUTION: This phosphorus adsorbent 8 is formed by sticking phosphorus adsorbing fine particles to a string-shaped member by holding action and adhesive action of gel like material. The gel like material for sticking the phosphorus adsorbing fine particles to the string-shaped member is preferably a gel whose solid phase component is alginic acid. In this phosphorus removing method, the dephosphorizing material is hung in water in the natural environmental water area such as rivers and lakes and marshes to adsorb and remove phosphate ions in water. The phosphorus adsorbent 8 can be hung in the river inflow part of lakes and marshes. The phosphorus adsorbent 8 is hung in water of lakes and marshes, aeration is performed from below the phosphorus adsorbent, and a water flow generated by the aeration is preferably contacted with the phosphorus adsorbent.;COPYRIGHT: (C)1999,JPO
