A2SBR工艺反硝化除磷系统的快速启动与稳定运行
Quick start-up and steady operation of denitrifying dephosphorization process by using anaerobic/anoxic sequencing batch reactor
摘要
Abstract
In order to achieve the simultaneous denitrification and dephosphorization from wastewater, a long-term lab experiment was carried out by using an anaerobic/anoxic sequencing batch reactor (A2SBR) to investigate the start-up and operation performance of denitrifying dephosphorization process. The result shows that under the conditions of influent COD mass concentration 200 mg/L, PO43--P mass concentration 4-11 mg/L and NO3--N mass concentration in anoxic phase from 25 mg/L to 55 mg/L, A2SBR process can be successfully started up within 31 d by using a periodical operation mode of anaerobic operation (2.5 h) -sludge sedimentation and water discharge (1 h)-anoxic operation (3.5 h)-sludge sedimentation and water discharge (1 h). The removal efficiency of COD, NO3--N and PO3-4-P in anaerobic phase are 77% , 90% and 84. 96% respectively. When the A2SBR was operated steadily, the removal efficiency of NO3--N, and PO43--P are 92% and 91% , respectively, and that of COD is higher than 80% , with the effluent mass concentration of PO4 3-P nearly zero. The whole system shows a good performance of denitrification and dephosphorization after a steady operation.关键词
