富营养湖泊的藻类现存量控制和供水处理的藻类去除

Control of algae standing crops in eutrophic lakes and the algae removal processes in water treatment for potable water supply

我国城镇供水正面临湖泊(水库)富营养化的严峻挑战。评述了高藻类现存量干扰水处理过程导致的供水问题,以及高藻类生物量控制对策和供水处理除藻工艺的国内外发展现状。就国内外现有藻类生物量控制对策和供水处理除藻工艺提出若干结论,并对我国今后在该领域的进一步研究提出建议。

Potable water supply is now facing a serious challenge of eutrophication of lakes (reservoirs) in this country. The problems with regard to potable water supply, caused by the in terference of high algae standing crops in raw water with water treatment process are enumerated. Current situation of domestic and foreign countermeasures of control and remediation for reducing algae biomass in lakes and the processes of algae removal in water treatment for potable water sup ply is reviewed in detail. The conclusions are presented and recommendations for the further devel opment in these fields in this country are also given from the available countermeasures and proces ses at home and abroad.
