The Preparation and Research of PVA Embedding Zr-AC Phosphorus Adsorbent
The hydration ZrOH was loaded in the powdered activated carbon（PAC）,the aim to modify activated carbon, then the mixed liquor including poval(PVA) and sodium alginate tech grade (SV) , as the embedding agent ,embedded the modified PAC.The main investigation were that the hydration ZrOH concentration,the ratio of embedding agent composition and Curing liquid ingredient etc. influence the phosphorus removal . The orthogonal experiment determined the optimum prepared conditions of embedding adsorbent. The experimental results showed that : the optimum loaded conditions were that PAC average particle size was 0.5-1.0mm, hydration ZrOH concentration was 0.04mol/L;the optimum embedded preparation conditions were PVA mass concentration for 8%，SV mass concentration for 1.2%; the optimum cured conditions were the curing liquid ingredient was saturated boric acid with 2% CaCl2. The adsorption of phosphorus removal efficiency was 99.27%.
