摘　　要：利用工业废渣粉煤灰和钢渣合成了两相复配高效除磷材料(EPRC),对模拟城市生活污水厂二级出水进行了除磷特性单因素试验。结果表明:当初始溶解性磷为5mg/L,两相复配EPRC投加量为32mg/L时,均能在30 h后将磷降低至1mg/L以下。初始pH=7比初始pH=4或10时的除磷效果更好。Coal ash and steel slag were used phosphorus removal composite. Single factor ban domestic wastewater plant in secondary terial could reduce the dissolved phosphorus phosphorization effects were better when pH as industrial waste residue to compound double element efficient assaying experiments under simulated phosphorus content of ureffluent were given. The results showed that 32 mg/L of each macontent from 5 mg/L to less than ] mg/L within 30 hours. The de- begins with 7 than 4 or 10.
