摘　　要：畜禽养殖废水中氮磷含量较高,必须脱氮除磷以避免造成河道的富营养化,为此采用新型除磷药剂-锁磷剂对畜禽养殖废水进行除磷试验,以考察锁磷剂对总磷(TP)的去除效果。试验结果显示,锁磷剂对畜禽养殖废水的除磷效果较为显著,当锁磷剂投加量为25mg/L时,对TP的去除率为54.32%,对TP的吸附量为113.52mg/g。另外,当投加量为50、100、150mg/L时锁磷剂的除磷效果与25mg/L相比差异不明显,综合考虑处理效果和经济成本,初步确定锁磷剂的适宜投加量为25mg/L。The wastewater from livestock and poultry breeding has a high content of nitrogen and phosphorus,which must be removed to avoid eutrophication in the river to prevent eutrophication in river water.In this study,a new phosphorus removal agent,phosphorus-locking agent,was utilized to conduct phosphorus removal experiments on wastewater from livestock and poultry breeding to assess its effectiveness in removing total phosphorus(TP).Experimental results indicated that the phosphorus-locking agent exhibited significant phosphorus removal efficiency from the wastewater.When the dosage of the phosphorus-locking agent was 25 mg/L,the removal rate of total phosphorus reached 54.32%,with an adsorption capacity of 113.52 mg/g.Additionally,no significant differences in phosphorus removal effects were observed at dosages of 50 mg/L,100 mg/L,and 150 mg/L.Taking both treatment efficacy and economic costs into account,the optimal dosage of the phosphorus-locking agent is preliminarily determined to be 25 mg/L.
