摘要
运用生命周期分析(LCA)可对不同的废水处理工艺方案进行选择和比较,优选出资源消耗和环境污染最少的实施方案。其技术关键在于如何将ISO14040等国际标准中规定的LCA方法学正确地应用至各种废水处理工艺的相对比较。本文对LCA应用于废水处理技术的一些基本概念进行了定义和探讨,其中包括废水处理系统的定义;废水处理厂的生命周期;废水处理工艺的功能、功能单位和基本流等。
Lifecycle assessment can be used to select different wastewater treatment alternatives to achieve the greatest potential waste prevention and resource reduction, which consists in how to apply LCA methodology regulated in international standards such as ISO14040 in the processes correctly This paper defines and discusses some basic concepts of the LCA application in wastewater treatment sector, including wastewater treatment system, lifecycle of the system, function and basic flow of the system
