摘　　要：以贵州瓮福磷矿废渣和工业废水为研究对象,采用磷钼酸喹啉重量法测定废水中P的含量;采用仪器分析方法测定废渣和水样中重金属元素Pb、Cd、Cr、Cu、As、Hg的含量,磷矿废渣中P含量采用ICP-AES法测定。结果表明,磷矿废渣和废水中P含量分别为1.20%和2.95 g/L,废渣中重金属元素含量依次为Pb>Cr>As>Cu>Hg>Cd,废水中重金属元素含量依次为As>Cu>Pb>Cd>Cr>Hg.据此,可以为瓮福磷矿区污染的调查、防治和治理提供依据。Guizhou Wengfu phosphate residues and industrial wastewater is the study subject, using quinoline phosphomolybdate gravimetric method for determination of P content in waste water; Method： using instrumental analysis methods and determination of residues of heavy metals in water samples Pb, Cd, Cr, Cu , As, Hg content of phosphate residues in P content by ICP-AES method. The results show that the phosphate residue and wastewater P contents were 1.20% and 2. 95 g/L, residue levels of heavy metals were Pb 〉 Cr 〉 As 〉 Cu 〉 Hg 〉 Cd. Content of heavy metals in wastewater were As 〉 Cu 〉 Pb 〉 Cd 〉 Cr 〉 Hg. Accordingly, for Wengfu phosphate pollution in the investigation, provide the basis for prevention and treatment.
