摘　　要： 应用细菌生长潜力 (BGP)法 ,考察了磷元素在淮河流域某地面水厂饮用水生物处理工艺中的限制因子作用 .原水添加 5 0 μg·L- 1KH2 PO4 P后 ,BGP可以提高 5 4 % ,添加其它无机元素和添加磷元素对BGP的影响没有显著差异 ;原水添加 2 0mg·L- 1C6 H12 O6 对BGP的影响要小于添加 5 0 μg·L- 1KH2 PO4 P的影响 ;原水添加磷后生物滤池对CODMn的去除率比对照生物滤池提高了 7 5 % ,其出水明显表现为碳限制型 ,对照生物滤池出水则为磷限制型 .结果说明磷元素是该水厂饮用水生物处理的限制因子 ,且限制作用强于碳元素 。 Bacterial Growth Potential (BGP) method was used to investigate the limiting effect of phosphorus in the biological process for drinking water treatment in a water plant in Huai River basin. BGP was increased by 54% when 50μg·L -1 KH 2PO 4-P was added to the raw water, while addition of other inorganic nutrients had no significant difference from the addition of phosphorus. The effect of addition of 20mg·L -1 C 6H 12 O 6 to raw water was not so strong as that of 50μg·L -1 KH 2PO 4-P. The COD Mn removal rate of the biological filter was 7.5 percentiles higher than the control one and carbon was the main limiting nutrient in its effluent when phosphorus was added to the raw water, while phosphorus was the main limiting nutrient in the effluent of the control filter. These results suggested that phosphorus was a limiting nutrient and had a stronger limiting effect than carbon on the biological process in this plant thus the removal efficiency of the organic matters could be increased by adding phosphorus to the influent.
