摘要
Abstract
Composite materials attapulgite/polyferric chloride ( APF) was prepared using attapulgite ( AG) and polyferric chloride (PFC ) as raw materials, and the obtained composite material was applied for treatment of low concentrated phosphate ( 1. 0-1. 3 mg/L ) containing wastewater. The effect of AG/PFC ratio, APF dosage, pH , reacting time and reacting temperture on treatment efficiency was investigated. Results showed that APF presented better performance than AG and PFC for TP removal, the best AG/ PFC ratio for APF composition was 7. The optimum treatment conditions were obtainedas follow; APF dosage was 0. 4 g in 200 mL KH2PO4 solution, pH ranged 7-8. 5, reacted temperture for 25 ℃, and reacted time for 40 min. Under these conditions, the TP removal rate could reach above 92% ,the effluent TP was lower than 0.1 mg/L, which could meet the second degree of surface water requirement standard (GB 3838-2002).关键词
