| 摘 要： | 分析在A/O工艺下,从其机理和现场运行,研究pH值对生物除磷影响.研究发现,厌氧条件下,pH值在6.0到7.5时,随着pH值增加,液相中磷质量浓度也增加.pH值为7.5时,磷质量浓度达到最高.随后pH增加,磷质量浓度随着下降.如果一部分污泥回流到初沉池进行水解酸化,厌氧池pH值降低有助于磷的有效释放.

| Abstract: | From theoretic and operation, under A/O process, the pH of anaerobic ettect on biological phosphorus removal is discussed and analyzed in this paper. The results showed that under anaerobic conditions, with pH increased from 6.0 to 7.5, the concentration of phosphorus also increases. When pH is 7.5, the concentration of phosphorus arrives it's top. Increasing pH along, the concentration of phosphorus will decrease. If activated sludge was recycled to first settle and organic matter was separated, the pH of anaerobic decrease is useful for anaerobic P-release. |
