| 摘 要： | 以地表水为水源的水厂及相对应的给水管网为对象,研究可生物降解溶解性有机碳(BDOC)的变化及主要影响因素.结果表明:在给水管网中BDOC的变化是余氯和细菌总数两个因素相互制约的结果;同时,水温也是一个很重要的因素,不同的季节BDOC的变化趋势也不同.

| Abstract: | For the water treatment plant with raw water coming from surface water and the corresponding distribution networks,this study investigates the variation of biodegradable dissolved organic carbon(BDOC) and factors affecting its variation.It is concluded that: the variation of BDOC concentrations in water distribution system is due to the balance of two factors: free residual chlorine and total bacterial counts;the water temperature is also a very important factor,and the variation changes with different seasons. |

| Keywords: | BDOC water distribution system biostability |
