【摘要】 针对海产品加工中高浓度含磷废水（1 000 mg/L）会恶化生物除磷的问题,通过化学絮凝法对高磷废水进行处理,分析了几种单一与混合絮凝剂的除磷效果。结果表明:聚合氯化铝与海泡石以质量比m_{聚合氯化铝}∶m_海泡石=10∶3制作的混合絮凝剂,在投加量为26 g/L,快速搅拌（160 r/min） 60 min,慢速搅拌（80 r/min） 30 min后,磷去除率最高,达到99. 68%。混合絮凝剂絮凝沉淀物的XRD分析表明,沉淀的主要成分为CaAl₃（PO₃OH）SiO₃,说明海泡石中含有的CaO和SiO₂成分对磷的去除有促进作用。更多还原

【Abstract】 To solve the problem that the biological phosphorus removal be aggravated by the high-concentration phosphorus-containing wastewater（ 1000 mg/L） in seafood processing,the high-concentration phosphorus-containing wastewater was treated by chemical flocculation method,and the phosphorus removal efficiency of several single and mixed flocculants were analyzed. The results showed that the mixed flocculant,which prepared by polyaluminium chloride and sepiolite with mass ratio m_{polyaluminum chloride}∶m_sepiolite= 10∶ 3,had the highest phosphorus removal rate of 99. 68% at a dose of 26 g/L,rapid agitation（ 160 r/min） for 60 min,and slow agitation（ 80 r/min） for 30 min. The XRD analysis of the precipitated flocculation agent after flocculation showed that the main component of the precipitate was CaAl₃（PO₃OH）SiO₃,indicating that the CaO and SiO₂ components contained in the sepiolite have positive effects on the removal of phosphorus.更多还原
