城市污水处理工艺:生命周期评价
Municipal wastewater treatment processes:life cycle assessment(LCA)
【摘要】 生命周期评价(LCA)作为环境管理中行之有效的重要工具,可对城市污水处理工艺技术的运行管理、能源资源利用及其环境影响等进行综合的评价,提供能源资源回收利用和削减(除)对环境不利影响的有效途径和方法,并为污水处理工艺技术的改进和优化提供重要依据。笔者旨在促进城市污水处理技术更好更快地向效能型和产能型及环境友好型方向发展,并结合LCA的主要内容和特点,重点评述了LCA在城市污水处理工艺,尤其是对基于高效厌氧处理技术实现有效水质处理和有效能源资源回收的关键性工艺的LCA研究和发展现状。
【Abstract】 Life Cycle Assessment(LCA), as an effective and important tool in environmental management, can be applied to the comprehensive evaluation of operational management, utilization of energy and resources and their environmental impacts of municipal wastewater treatment technology, which will provide effective ways and means for recycling energy and resources, reducing or eliminating adverse environmental impacts and upgrading or optimizing the wastewater treatment processes as well. In order to promote the better and fast transformation of municipal wastewater treatment technology to the pattern of resource-utilization, energy-efficiency and production, a comprehensive review was made in this paper on the application of LCA in municipal wastewater treatment processes, especially in the key and high efficient anaerobic process and technologies characterized with high quality effluent and effective energy/resource use, based on the introduction to the main contents and characters of LCA.
