废水生物处理过程的能流与能效分析

废水生物处理是一个能耗密集型过程 ,其能耗费用是废水处理厂运行费用的主要部分 ,所造成的经济费用以及环境影响问题正受到日益严重的关注。本文就废水生物处理过程的运行能耗以及废水生化潜能 (BEP)的变化进行了分析探讨 ,对于正确识别不同废水生物处理工艺的能耗与能效 ,正确进行处理技术选择与决策具有重要的实际意义。

ENERGY FLOW ANALYSIS IN WASTEWATER BIOLOGICAL TREATMENT PROCESS

Wastewater biological treatment is an energy-intensive process which has received considerable attention with regard to energy consumption and correlative environmental problems.In fact,the proportion of sewage treatment plant operating budgets allocated to energy has been basic and predominant.This paper discussed the operational energy flow of the biological treatment process of wastewater and the changes in the biochemical potential energy in the process,which is of importance for identifying the energy consumption and energy efficiency of different wastewater treatment processes as well as their choice and decision making.
