Study on the Prepartion of Slag Haycite for Phosphorus Removal Using Ammonium Hydrogen Carbonate as Pore Former

Abstract:

Porous slag haycite for phosphorus removal was made from slag, as the main raw material, clay, as binder, and ammonium hydrogen carbonate, as a pore forming agent. And the influence of material ratio and sintering condition were investigated. The best ratio of steel slag: Clay: ammonium hydrogen carbonate was 53.5%:42.5%:4% as ascertained, and the best sintering temperature 800°C, sintering time 60min. The porosity of slag haycite was 2 times more than original slag, and the specific surface area was increased evidently, thus very conducive to microbial growth.
