| 摘要: |
| 为研究常规水质指标和生物稳定性的相关性,以我国东北某城市某小区供水管网为对象研究生物稳定性.采用生物可降解溶解性有机碳(BDOC)作为指标评价管网水的生物稳定性,并对管网中影响BDOC的因素进行统计分析.结果表明,管网水中BDOC变化范围为0.11～0.40 mg/L,属于生物稳定的饮用水,从管网入口到管网末梢,沿程各点BDOC变化不大;常规水质指标中,浑浊度和BDOC是正相关,而pH和BDOC是负相关.控制管网水中细菌的再生长,不能单单控制生物稳定性指标,应该把BDOC的控制与余氯的控制和浑浊度的控制结合起来进行. |

| Abstract: |
| To study the correlation between traditional water quality indexes and BDOC,the biological stability of drink water in a northern city water system was investigated and evaluated by BDOC.When the conentration of BDOC is between 0.11 mg/L and 0.40 mg/L,the water is in biological steady level.BDOC changed a few from the entry to the end in the network.Among traditional water quality indexes,turbidity presents a positive correlation with BDOC,while pH shows a negative correlation.The charges of BDOC and residual chlorine should be combined together to control bacteria re-growth in the network,not merely depending on the biological index. |
