硅基沸石滤料A/O生物滤池挂膜启动的研究

Study on the Start-up of A/O Biofilm Process With Silicon-based Zeolite Filter Material

通过研究分析硅基沸石滤料A/O生物滤池的挂膜启动,以及考察系统出水CODCr、氨氮和总氮浓度在挂膜启动过程中的变化,分析挂膜启动的发展进程,寻求判断挂膜启动完成的合理理化指标,以期为A/O生物滤池的挂膜启动提供理论依据。

The start-up of A/O bio-filter was studied and reasonable indexs for the judgment of the start-up were found to provide the theory basis for the start-up of A/O bio-filter with silicon-based zeolite filter material. The study makes use of the natural start-up compound with inoculum start-up. The start-up of A/O bio-filter with silicon-based zeolite filter material was investigated by measuring the concentrations of CODCr, ammonia and total nitrogen in the effluent.
