Abstract
A series analyses have been done to character neutralised acid residue form synthetic rutile industry. Column sorption experiments have been conducted to investigate the attenuation of DOC and nutrients in polluted water using neutralised acid residue form synthetic rutile industry. After 145 d, DOC, TP, PO4-P, TN, NH3-N, NOx-N and DON in neutralised acid residue/sand column eluent are reduced by 88.9%, 94.9%, 99.1%, 63.5%, -107.3%, 71.2% and 77.7%, DOC, TP, PO4-P, TN, NH3-N, NOX-N and DON in sand column eluent are reduced by -0.3%, -50.1%, -44.8%,- 10.8%, -298.2%, 86.3% and -28.5%, respectively. The cumulate removal rate of DOC, TP, PO4-P, TN, NH3-N, NOX-N and DON by neutralised acid residue are 88.9%, 96.6%, 99.4%, 67.1%, 47.9%, -110.1% and 82.7% by calculation, respectively. Neutralised acid residue exhibits good sorption of DOC and nutrients. Neutralised acid residue is testified to be safe by Microtox® test and benefit of reducing the water pollution.
