快速渗滤生态工程冬季运行热平衡研究及其在系统设计中的应用

Thermal balance of rapid infiltration eco-engineering during winter-operation and its application in system design.

本文以快速渗滤中试生态工程冬季运行实验为基础,讨论了系统在布水、融冻、渗滤及暴露过程中能量补充与损失的途径,建立了池底裸露与有冰层覆盖条件下的热平衡数学模型,扩展了快速渗滤土地处理的系统设计程序,分析了场地、工艺及运行条件对系统热量损失及净化功能的影响,为快渗系统设计与冬季安全运行提供了理论根据。

On the bases of pilot scale winter-operation experiments of rapid infiltration eco-engineering, the channels of heat supply and its loss in RI system during wastewater distribution, its melting, infiltration and exposure are discussed. The mathematical models on thermal balance under naked pond bottom and ice cover conditions are established, and the system design procedure of RI system is significantly extended. The effects of site, technology and operating conditions on thermal loss and purification functions of RI system are analysed, which provides theorititcal foundations for system design and winter-operation.
