钛合金阳极氧化工艺对环境的潜在危害

摘要

基于钛合金阳极氧化工艺流程,对工序中可能对环境产生影响的关键环节进行了分析;从＂三废＂角度系统分析了工艺流程中产生的废水、废气、废渣的成分,并提炼出对环境、人体有严重危害的化学物质及其潜在危害途径;针对工艺流程中产生的废水中的酸碱、重金属、氰化物,废气中的含尘气体、酸碱雾,废渣等提出了合理的防治、处理措施,力求减少钛合金阳极氧化工艺流程中产生的有害物质对环境及人体的危害。%Based on titanium alloy anode oxidation process,the key links of the process which will possibly influence the environment were analyzed.The compositions of wastewater,waste gas and waste residue generated in the process were analyzed systematically from the point of view of ＂three wastes＂.The chemical substances,which are seriously harmful to the human body and environment,and their potentially harmful ways were abstracted.The reasonable prevention and treatment measures based on acid-base,heavy metals and cyanide in the wastewater,exhaust gas and acid fog in the waste gas and the residue from the process were proposed,which would be helpful to reduce the harm to the environment and human body.
