摘要
利用顺流平板式和套管式两种不同曝气器进行了黑臭河道曝气试验。结果表明,顺流平板式-曝气器对黑臭河道水体的复氧效率及对水体中CODcr、NH3-N的去除效率都好于套管式-曝气器;另外,不同曝气器对不同水层深度的造流效果不同,顺流平板式-曝气器对浅水层的造流效果好于套管式-曝气器,而套管式-曝气器对深水层有较好的造流作用。
The aeration experiment of black-odor river was conducted by the use of two new pattern of aerator equipments,which are slab aerator and cannular aerator.The results shown that the aeration efficiency and the removal ratios of CODcr,NH3-N between both aerator equipments were different,slab aerator was better than cannular aerator.In addition,the current generating efficiency between both aerator equipments was also different.The current generating efficiency of slab-aerator was better than cannular-aerator in shallow water layer,at the same time,more advantage of cannular-aerator was in deep water layer.
