摘 要:
本研究拟利用页岩空心砖内部空隙提高湿地系统内部供氧能力,以增强湿地系统的净化能力。研究表明:构建的自动供氧湿地系统(A系统)泥土层、粉煤灰层基质层溶解氧含量以及对磷的去除率均高于人工强化供氧湿地系统(B系统)对应基质层,而A系统底部砾石层基质溶解氧含量和对磷的去除率则低于B系统砾石层,经A系统处理后的废水中磷含量略低于人工强化供氧湿地系统。由此说明,构建的自动供氧型湿地系统内部具有较强的供氧能力,其内部供氧水平以及对磷的净化效果可与人工强化供氧型湿地系统相媲美

摘 要:
The inter space of shale hollow bricks was utilized to enhance the internal oxygen supply capacity of wetland system,so that it could enhance the purification of wetland system. The experimental result indicated that dissolved oxygen( DO) contents and phosphorus removal rates of clay layer and fly ash layer in self-aeration wetland system( system A) were higher than those of artificial enhanced oxygen wetland system( system B),which was opposed in gravel layer. Phosphorus content in waste water treated by system A was slightly lower than that of system B. It presents that the self-aeration wetland system had strong oxygen supply capacity,its internal oxygen supply level and phosphorus purification could rival self-aeration wetland system.
