为研究高浓度含磷废水的处理,在实验室配制了100mg·L-1的磷酸钠溶液模拟高磷废水,采用单因子考察法系统探讨了投加方式和pH对高磷废水处理效率的影响。运用磷钼蓝分光光度法分析了处理后的高磷废水中磷酸根离子的含量。结果表明：钙法除磷中,氢氧化钙的最佳投加方式为先投加75%,取得上清液再投加25%,最佳pH为11。
為研究高濃度含燐廢水的處理,在實驗室配製瞭100mg·L-1的燐痠鈉溶液模擬高燐廢水,採用單因子攷察法繫統探討瞭投加方式和pH對高燐廢水處理效率的影響。運用燐鉬藍分光光度法分析瞭處理後的高燐廢水中燐痠根離子的含量。結果錶明：鈣法除燐中,氫氧化鈣的最佳投加方式為先投加75%,取得上清液再投加25%,最佳pH為11。

In order to research on treatment method of high-phosphate acidic waste water,100 mg·L-1 sodium phosphate solution was prepared in the laboratory to simulate high-phosphate acidic waste water.Single factor method was used to systematically research the influence of dosing method and pH on high-phosphate acidic waste water treatment.Phosphorus molybdenum blue spectrophotometric method was used to analyze the treated high-phosphate acidic.The results showed that the best dosing method of biocalc was first 75% dose,then 25% dose in the supernatant fluid,the best pH was 11.
