基于发光菌采集的河水化学污染度测试方法

The Water Chemical Pollution Test Method Based on Luminescent Bacteria to Collect

针对传统的水质分析过程往往采用化学方法,容易造成二次污染。提出一种新的利用生物发光菌对河水化工污染等级进行测试的方法。通过分析发光菌的发光原理,利用有毒化学物质诱导细菌发光反应以及有毒物质抑制发光酶促反应的光减弱原理,对化学元素反映出不同的光强度特征进行采集,构建了发光细菌在化学污染环境下的可测量生长曲线。最后通过发光细菌毒性试验,建立发光细菌在一些重金属和有机污染物毒性作用下的发光强度的变化曲线,测定和判断水质受污染的等级。该方法的实验结果表现出较强的有效性和适应性,取得了较好的效果。

According to the traditional process of water quality analysis often adopt chemical method, easy to cause sec-ondary pollution. In this paper, a new use of bioluminescent bacteria test method for chemical pollution level in the river. Finally by photobacteria toxicity test and built luminescent bacteria in some toxic heavy metals and organic pollutants un-der the action of the change of the luminous intensity curve, to determine and judge the water quality of pollution levels, the method and effectiveness of the experimental results show the strong adaptability, good results have been achieved.
