摘要:
以水生植物为核心的生态修复技术日益向污水处理领域拓展,但因其占地面积大导致应用受到一定的限制. 为提高水生植物系统的净化效能,设计了一种凤眼莲融合活性污泥好氧净化系统,实验研究了该系统对低碳氮比生活污水的净化效能并分析了其净化机理. 结果表明,单独凤眼莲对污水中的氮磷去除效能较微生物低,但构建凤眼莲融合活性污泥好氧净化系统可同时发挥植物吸收和生物降解的作用,显著提高N、P、COD等污染物的去除效果,为污水植物净化系统的工程应用提供有益的依据.
Abstract:
The ecological restoration technology based on aquatic plants is increasingly expanding into the field of sewage treatment,but the application is limited due to its occupied large area. To improve the efficiency of the aquatic plant purification system,a purification system of Eichhornia crassipes combined with activated sludge is designed. The purification efficiency of domestic wastewater with low carbon and nitrogen ratio is studied and its purification mechanism is analyzed. The results show that the removal efficiency of nitrogen and phosphorus in the single system of Eichhornia crassipes is lower than those of microorganisms. However,the aerobic purification system of Eichhornia crassipes combined with activated sludge can exert plant uptake and biodegradation at the same time,which can significantly improve the removal efficiency of N,P,COD and other pollutants. It provides a useful basis for the engineering application of sewage plant purification system.
