Abstract

The study explored the treatment of different wastewater by producing microelectronic components. It proposed using aerobic biological treatment for the first effluent containing tetramethyl ammonium hydroxide and chemical-physical processes for the other two streams having fluorides, phosphates, nitrates and acetic acid. The novel integrated process significantly reduced environmental impacts by an average of 50 % compared to current disposal methods. The economic analysis indicates a 30 % reduction in treatment costs for the first effluent and lesser reductions for the other two effluents. The study revealed that treating all three effluents in an integrated manner is cost-effective, reducing investment and operating costs.

应用生命周期评估和生命周期成本计算处理微电子工业废水

这项研究探讨了如何处理生产微电子元件过程中产生的不同废水。它建议对含有四甲基氢氧化铵的第一种废水采用好氧生物处理法，对含有氟化物、磷酸盐、硝酸盐和醋酸的另外两种废水采用化学物理法。与目前的处理方法相比，这种新型综合工艺大大减少了对环境的影响，平均减少了 50%。经济分析表明，第一种污水的处理成本降低了 30%，其他两种污水的处理成本降低幅度较小。研究表明，以综合方式处理所有三种污水具有成本效益，可降低投资和运营成本。
