摘    要:根据不同成分的水样中细菌再生长情况,研究了水中磷对生物稳定性的限制因子作用。结果显示,在测试水样中添加1 mg/L的NaAc后,细菌总数增加了100%-187%;在水样中添加15μg/L的NaH2PO4后,细菌总数增加了180%-203%。随水样中PO43-P含量的增加,细菌数目也在逐渐增加,但当水中PO43-P的含量大于等于5μg/L时,细菌已无明显增长趋势。试验结果表明磷和碳一样也是水中微生物生长的限制因素之一,并且对于该水样当PO43-P的含量为2μg/L—5μg/L之间的某个值时,磷的限制作用将会表现出来。

关 键 词:  细菌总数  细菌再生长  生物稳定性  饮用水

Abstract:Restrictive effect of phosphorus on the biological stability of drinking water was studied based on the re-growth of microbe in different samples.Result showed that number of microbe increased about 100~ 187% when 1 mg/L of NaAc was added to water,and increased about 180~ 203% when 15 μg/L of NaH2PO4 was added.As content of phosphorous in water increased,microbe grew gradually.When phosphorous reached 5 μg/L,microbe exhibited no significant increase,which showed restrictive effect of phosphorus on the growth of microbe in drinking water.
Keywords:phosphorus  number of bacterium  bacterial re-growth  biological stability  drinking water
