Phosphorus and Nitrogen Removal from Sewage by Modified Honeycomb Cinder

Abstract:

The study aimed at phosphorus and nitrogen removal by honeycomb cinder modified with Zinc chloride (ZnCl₂). By bench-scale batch experiments, honeycomb cinders with different modification time and ZnCl₂dosage were modified and its adsorption capacities were evaluated by methylence blue as the adsorbate. Under the optimal modification conditions, large amount modified honeycomb cinders were prepared to remove the phosphorus and nitrogen from domestic sewage, which different operating conditions of honeycomb cinders dosage, and contact time were considered. The results show that removal efficiencies of total phosphate (TP), orthophosphate (PO₄³-P), total nitrogen (TN) and ammonia nitrogen (NH⁴⁺-N) could reach 89.9%, 96.7%, 18.9% and 23.3% under the optimal conditions, respectively. Modified honeycomb cinders might be an effective and low cost adsorbent for phosphorus removal.
