发光细菌法用于给水系统的毒性监测及预警

利用生物发光细菌,选择81.9%低毒性样本测试模式,于2006年2月-2007年2月,对宁波供水体系中的7个主要水源、5个水厂出厂水及相应的管网水水样连续进行了2次/月的发光细菌生物毒性监测,并建立了这17个监测点的毒性控制限.研究结果表明,水库水的耗氧量与其生物毒性呈正相关关系,但河水则不符合此规律;加氯后的原水和出厂水,其生物毒性要增强,进一步研究发现,原水耗氧量与加氯后水的生物毒性也呈正相关关系;管网水与出厂水的生物毒性基本一致,但需进一步研究其在管网中的变化规律;发光细菌法可用于给水系统的毒性监测及预警.

Application of Luminescent Bacteria Test to Toxicity Monitoring and Early Warning of Water Supply System

From February 2006 to February 2007,the biological toxicity monitoring of the water samples collected from seven main water sources,five waterworks outlets and five pipe networks of Ningbo water supply system was carried out continually twice per month using bioluminescent bacteria and selecting 81.9% lower toxic test mode.The toxicity control limits of the seventeen monitoring points were built.The research results indicate that the oxygen consumption of reservoir water has positive correlation to its biot...
