摘要
生物—生态优化组合工艺试验规模为100m3/d,通过探索自然启动阶段生物—生态的优化组合模式,提高了启动中组合工艺的处理效能、缩短了处理效能波动时段,实现了向运行阶段的平稳过渡,为工程规模的启动提供了系统依据。研究表明,在启动阶段通过生物-生态优化工况组合,可达到组合工艺COD去除率90%、TN去除率40%～70%、TP去除率90%的去除效果。
In this work, an ecological wetland sewage treatment demonstration project, with a scale of 100 m^3/d was established, aiming to test the workability of Biological-Ecological Combinative Technology. The optimal combinative technology of biological and ecological unit in start-up stage could not only improve the performance but also shorten the unstable phase of substrate removal. The results of this study have indicated that the removal of COD, total nitrogen, total phosphorus during start up stage are 90%, 40%--70% and 90%, respectively.
