摘要
氮、磷是水体富营养化和蓝藻水华发生的主要驱动和限制因子,是饮用水水质监测所关注的重要指标。本研究在盐城市龙冈镇境内蟒蛇河南岸设计构建了饮用水水源生态净化工程中试系统,沿中试系统水流方向依次布设5个水质采样点,分别位于进水口和预处理区、挺水植物区、沉水植物区与深度净化区的出水口,通过近1年的运行研究表明,该工艺对水体有机物及营养盐去除效率高,净化效果好,出水水质稳定达到地表Ⅲ类水标准,且感官效果良好,出水透明度可达2 m。
Nitrogen and phosphorous are the main factors and drivers for the happening of entrophication and blue algae and also important indicators for the monitoring of drinking water quality.The study creates a design of a pilot system of drinking water source purification in the south bank of Mangshe River and places five sampling points along with the direction of flow,namely intake,pretreatment area,emerged plant zone,submerged plant zone and deeply purification zone.After one year’s operation,it is found that the technique is capable of eliminating organic matter and nutritional salt effectively and increasing purification degree to 2 meters,and also enables water quality to meet class-III standard.
