摘　　要：本文介绍钙法处理高浓度含磷废水技术的研究结果,控制关键技术参数反应pH、最适沉淀表面负荷、沉淀时间及反应、混合强度等,在进水磷酸盐:60-80mg/L时,处理出水磷酸盐小于0.5mg/L,去除率为99.7%-99.9%。该技术适用于非生物处理可解决的高浓度含磷污水的处理和城市污水厂的深度处理。In this paper phosphate removal of high-concentration phosphorus-containing wastewater by using calcium precipation was studied.The lab and full-scale experiments showed that at phosphate of 60～80mg/L the removal efficiency of phosphate was 99.7%～99.9%,and effluents had only phosphate of 0.03～0.08mg/L.This methed is suitable for phosphate removal of high-concentration phosphorus-containing wastewater which can not be treated by biological methods .It can also be used for of advanced treatment of municipal wastewater.
