水源型湖库异味成因分析与控制方法研究

Analysis of Odor Cause and Study of Control Method for Water Source Lake Reservoir

我国湖库众多,各类湖库在人们的生产生活中均起着至关重要的作用。而如今湖库污染越来越严重,水体异味问题突出。分析了作为饮用水水源地的湖库异味产生的主要原因为藻类等微生物的新陈代谢和有机物的厌氧分解,并在此基础上提出了防止水体异味产生的方法,对水体建立起藻类爆发的预警机制,确定藻类可能爆发的潜在区域,针对性地投加化学增氧剂,从而快速解决水体产生异味的问题。

There are many lake reservoirs in China.All kinds of lake reservoirs play an important role in the production and life of the people.But now the pollution of lake reservoirs is more and more serious and the water odor is a serious problem.The analysis result shows that the main causes of odor in the lake reservoir as the drinking water source are the metabolism of alga and other microbes,and the anaerobic decomposition of organic matter.On this basis,the method to prevent the water odor is put forward.The early warning mechanism for algae blooms in water is established to identify the potential area for algae blooms.The chemical oxidizer is specifically dosed so as to quickly solve the odor problem in water.
