曝气一生态浮床治理氮磷污水净化效果研究

Study on the Purification Effect of Nitrogen and Phosphorus Sewage in Aeration-Ecological Floating Bed Treatment

为强化生态浮床对重污染河道水体的净化能力,通过设置曝气-电解强化生态浮床和生态浮床装置,分析水中氮﹑磷营养盐净化情况,并进行对比分析。结果表明,曝气-电解的联合作用有利于水体中氮元素物质的去除,且曝气可使污染水中出现大量好氧菌,使微生物硝化能力加强,提升浮床净化能力;由于溶解氧含量较低,传统浮床对污染水氮元素物质具有一定的去除能力,但能力弱于曝气-电解强化生态浮床装置;曝气-电解强化生态浮床装置对污染水磷元素物质去除作用较强,但因为曝气作用有限,主要源于电解作用。研究结果可为实际工况提供参考。

In order to strengthen the purification ability of ecological floating bed for heavily polluted river water bodies,by setting up aeration-electrolytic to strengthen the eco-floating bed and eco-floating bed devices,analyze the purification of nitrogen and phosphorus nutrients in water,and to make a comparative analysis.The results show that the combined effect of aeration-electrolysis is beneficial to the removal of nitrogen elements in water,and the aeration can make a large number of aerobic bacteria appear in the contaminated water,to enhance the microbial nitrification capacity,improve the purification capacity of the floating bed;due to the low intersection of the dissolved oxygen content,the traditional floating bed has the ability to remove the nitrogen elements from the contaminated water,but the ability is weaker than the aeration-electrolysis strengthening ecological floating bed device;aeration-electrolytic enhanced ecological floating bed device has a strong effect on the removal of polluted water and phosphorus elements,but because the aeration effect is limited,mainly derived from the electrolysis action.The research results can provide a reference for the actual working conditions.
