地表水源热泵系统尾排水对水环境影响的研究综述

The Impact of Tail Water on Water Environment in the Surface Water Source Heat Pump Systems

通过对前人研究进行总结,综述了尾排水对水环境影响的研究进展,其中包括对温排水数值模拟的研究,对水生生物以及水体富营养化进程影响的研究等。分析认为地表水源热泵系统的尾排水会引起局部水温变化,并将影响水生生物的生长繁殖和加快水体富营养化进程。其影响大小主要取决于进出水的温差和水排放量,也与水源的水文地质特征密切相关。针对地表水源热泵系统应用现状,提出了几点针对性的建议。

Based on the former results, summarize the progress in the research of discharge for water environment, including the research of numerical simulation, influence research on hydrobiontes and the development of eutrophication. Conclude that surface water heat pumps discharges can change local water temperature, and the higher water temperature would probably change the growth and reproduction of hydrobiontes and the tenor of eutrophication. The degree of this effect was decided in the quantity of effluent water and temperature difference between influent and effluent, and it also has close relation with the hydrogeological feature of water resource. Suggest researching deeply systematically the influence as soon as possible, and developing the key technology.
