Abstract:
The growth of heterotrophic bacteria and the variation of some physical chemical parameters were studied in a full-scale water distribution system in Shanghai. The results showed that, in the water distribution system in Shanghai, heterotrophic bacteria fed on organics were the major population in pipe water. With the water supply distance extending, BDOC in water increased and correspondingly both the number of heterotrophic bacteria and turbidity increased. In addition, the changes of different forms of nitrogen showed the existence of nitritification in water, and the amount of nitrite increased along the number of heterotrophic bacteria. Our results also showed that the increase of total phosphorus correlated well with that of heterotrophic bacteria in pipe water.
