摘要
采用热力学方法研究了污水处理工艺的能量利用,认为其基础是污染物化学能的界定和计算。依据热力学第一定律建立了污染物化学焓概念,统一了化学焓计算的基准,确定了复杂有机物化学焓的计算方法,并将其与常规水质指标COD相耦合。通过研究使得污水处理工艺各种过程能量分析的结果、不同形式的能量之间具有了可比性,同时也易于与常规的水质测定手段衔接。
Thermodynamic approach is applied to energy utility of wasterater treatment process, definition and calculation of pollutants' chemical energy would be primary. According to the First Law of Thermodynamics, the concept of pollutants' chemical enthalpy advanced, and criterion for calculating chemical enthalpy is integrated, and enthalpy calculation method of complex organic substances established too in this paper. Then enthalpy was coulped with traditional water quality index-COD. Energy analysis conclusions of various processes in wastewater treatment and different classification energy can be comparable through the study, energy index becomes easy to be linked up with traditonal water quality mensuration.
