摘要
目的研究粪大肠菌群快速检测仪检测污水中粪大肠菌群的准确性和可靠性。方法采集有代表性的化粪池出水和医院污水样品17份,采用粪大肠菌群检测仪检测其中粪大肠菌群。同时用多管发酵法作为比对,分析两种方法检测结果之间的差异。结果大肠菌群快速检测仪的测定结果与多管发酵法测定结果的偏差在±10%之内,经t检验,两种方法检测结果之间的差异无统计学意义(t=2.365,P>0.05)。结论粪大肠菌群快速检测仪可用于污水中粪大肠菌群的快速检测。
Objective To study the accuracy and reliability of fecal coliform in sewage by rapid detection instrument of fecal coliform. Methods 17 typical samples of fecal coliform were detected from septic tank effluent and medical institutions sewage with rapid detection instrument of fecal coliform and multiple tube fermentation method simultaneously, and the difference between them was analyzed. Results The deviations of the measurement results between the two methods ranged ± 10%, and the difference between the results of the two methods for detecting was not statistically significant after the t - test. Conclusion The rapid detection instrument of fecal coliform can be used for the rapid detection of fecal coliform in the sewage.
