污水生物处理单元能量平衡与分析方法研究与应用

在提出污染物内能概念的基础上，对污水生物处理工艺能量平衡和分析的原理与方法进行了探讨，建立了能量平衡研究的基本模型。据此对国内四座不同工艺的城市污水处理厂进行了生物处理单元的能量衡算，并采用两类指标对处理单元耗能状况进行了评价。应用能量平衡分析方法可进行处理工艺的设计遴选和建成后运转效果的评判，以及指导处理厂有针对性地采取节能降耗措施。

Study and application on energy balancing and analyzing approach for biological wastewater treatment unit

Based on concept of internal energy of pollutants, principles and approaches for energy analysis are discussed, and basic model for energy balancing are founded. Energy balance computation is performed for biological treating units of 4 municipal wastewater treatment facilities which various processes are adopted. Energy consuming state is evaluated through two sorts of indexes. The author think that energy balancing and analyzing approach proposed is fit for processes selection during project designing stage and for performance effect evaluation during running stage when energy conservation measures concerned could be taken.
