| Summary: | Nitrification is an effective technology to control nitrogen pollution from wastewater. The effect of pH on nitrification and the relationship between pH and alkalinity were analyzed. It was shown that pH exerted not only a large influence on the growth and metabolism of nitrifying bacteria but also the availability and toxicity of substrates and products. To a great degree, pH restricted the performance of nitrification reactor. The alkalinity of the nitrification system was mainly contributed by carbonates present. Because of the small buffering capacity of carbonates at pH 6.5-8.5, during the nitrification process the pH to being under control tended to fluctuate markedly and measures should be taken in advance. |
