摘要
Abstract
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.关键词
