【摘要】 论文对炼钢厂钢渣进行了一系列的特性分析,并通过圆柱试验了解其对水中溶解性有机碳(DOC)和营养物质的去除性能。为了保证试验圆柱良好的透水性,在试验圆柱中添加了石英砂,并设置了石英砂对比圆柱。通过64 d试验,钢渣对水中DOC、PO4-P、TP、NH3-N、NOx-N、DON和TN的去除率分别为51%、99%、87%、-15%、32%、29%和23%,吸收容量分别为6 317 mg/kg1、35 mg/kg、126 mg/kg-、14 mg/kg2、7 mg/kg1、54 mg/kg和167 mg/kg。试验表明,钢渣对水中的有机物和营养物质有很好的去除效果。更多还原

【Abstract】 A series of analyses have been conducted to the characteristics of steel slag.Column sorption experiments were also conducted to investigate the attenuation of nutrients and DOC in wastewater using steel slag.After 64 days,DOC,PO4-P,TP,NH3-N,NOX-N,DON and TN were reduced in the column effluent by 51%,99%,87%,-15%,32%,29% and 23% respectively.The absorptive capacity of steel slag of DOC,PO4-P,TP,NH3-N,NOX-N,DON and TN after 64 days was 6 317mg/ kg,135 mg/ kg,126 mg/ kg,-14mg/ kg,27mg/ kg,154 mg/ kg and 167 mg/ kg.Steel slag exhibits good adsorption of DOC and a range of nutrients.更多还原
