低温对EBPR系统生物除磷特性的影响
Effect of low temperature on EBPR system
摘要
Abstract
In order to investigate the effect of low temperature on EBPR system, an anaerobic/aerobic SBR system was used for treating real domestic wastewater. The system ran at 20 'C, and the phosphorus removal efficiency kept above 90% steadily. Then the system ran in low temperature conditions (15,10 and 5'C). The results show that the phosphorus release ratio at the four temperatures (20, 15, 10 and 5 'C) is 358.5%, 358.5%, 247.8% and 209.1% with the VFAs usage ratio at 100%, 88.9%, 58.4% and 33.8% in each case separately in anaerobic phase. And the phosphorus uptake rate of each case is 11.67, 6.43, 2.24 and 1.34 mg/(g-h) during the first 30 min of aerobic phase. According to the experimental results, EBPR system still runs well at 15 ℃, and deteriorates at 10℃ and 5 ℃. Glycogen accumulating organisms (GAOs) are inhibited obviously below 10 'C .关键词
