摘要
在总结前人研究的基础上,综述了温排水及低温水对水环境影响的研究进展。其中包括温排水数值模拟的研究,对水生生物及水体富营养化进程影响的研究进展情况。分析认为地表水源热泵尾水排放会引起局部水温变化,且温排水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排放量,也与水源的水文地质特征密切相关。提出了对其深入系统研究的重要性和迫切性,并提出应当尽快开发排放口布置及原位冷却等尾水污染控制关键技术,建立地表水源热泵尾水污染综合评价指标体系和评估方法。
Based on the former results, summarize the progress in the research of thermal discharge for water environment, including the research of numerecal simulation; influence research on Hydrobionts and the tenor 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 Hydrobiont 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 hydrology and geology quanlity characteristics of water resource; Suggest to research deeply Systematically the influ- ence as soon as possible, and development the key technology about layout of output and local cooling ,constitute the water environmental impact assessment index systems and evaluation Method of surface Water Heat Pump Systems discharge.
