【摘要】 对洪泽尾水生态处理工程进行调研,为其他生态工程设计和管理提供参考。结果表明:洪泽生态工程运行效果良好,在进水水质接近一级B排放标准的情况下,总出水主要水质指标优于一级A的设计标准。南线工程净化效果优于北线工程,南线出水COD、TN、TP分别低于20、2、0.02 mg/L,北线出水COD、TN、TP分别低于60、8、0.1 mg/L;洪泽生态工程设计合理、管理规范,但仍有细节需要完善,其他生态工程设计时,潜流湿地要注重基质的选择,曝气塘运行管理过程中,要注重曝气及挂膜效果,提高工程的净化效率。更多还原

【Abstract】 A research on the ecological treatment project of Hongze tail water was carried out to provide a reference for the design and management of other ecological projects. The results showed that the operation of Hongze ecological engineering was good, and the main water quality index of the total effluent was better than the effluent standard of First grade A in the case that inlet water quality is close to effluent standard of First grade B. The cleaning effect of South Line Project was better than the North Line, the concentration of COD, TN and TP in the effluent of the South Line Project Engineering was lower than 20, 2 and 0.02 mg/L, respectively, while the water quality index of the North Line Project Engineering was lower than 60, 8 and 0.1 mg/L. Hongze ecological engineering was reasonable and the management was standardized, but there were still details that need to be improved. In other ecological engineering design, we should pay attention to the choice of matrix in Subsurface wetland design and the aeration performance, biofilm culturing in the process of running and management of aerated pond in order to improve the purification efficiency of the project.更多还原
