【摘要】 介绍势能增氧生态床的增氧机理及工程实例。生态床为多层浅床结构,每层装设填料,采用虹吸管进出水,利用水流势能进行大气复氧,水中DO逐层增加,出水DO达到最高。结构紧凑,投资省,高效节能,可用于小区中水回用处理,经济效益优于传统工艺。更多还原

【Abstract】 It was introduced the oxygen increasing mechanism and practical project of an ecological bed. It was composed of many shallow layers. Each layer is provided with fillers. Through siphon the water could flow into and out from the bed. It used potential energy to recover oxygen. Through each layer the dissolved oxygen in water could be increased gradually. This process had high efficiency.It was very compact and easy to operate. It only need less investment and could save energy. Contrast to traditional process,the ecological bed had notable economical benefit when applied to residential wastewater reuse.更多还原
