某市饮用水生物稳定性的研究及对策

Research on Biological Stability of Drinking Water in a City

对某市自来水进行了生物稳定性研究 ,结果表明 :传统处理工艺的出水中AOC浓度高达30 6 4μg/L ,已超过饮用水生物稳定性标准 (10 0 μg/L) ,试验工艺在混凝沉淀后增加生物处理单元 ,其出水中AOC浓度为 49μg/L 。

Biological stability of drinking water in a city is studied. The result shows that the concentration of AOC in discharged water treated by traditional process is 306.4 μg/L, exceeding the standard of biological stability in drinking water (100 μg/L). Biological treatment unit is added after coagulation precipitation in trial process, the concentration of AOC in discharged water is 49 μg/L (less than standard value 50～100 μg/ L),biological stability of drinking water is guaranteed.
