摘要
目的-对攀钢工业循环冷却水中异养菌生长情况进行检测,对循环冷却水中异养菌的生长控制效果进行初步探讨。方法-采用平皿培养计数法对异养菌进行培养检测。结果-共检测376个水样,超标119个,不合格率为31.65%。结论-异养菌的生长控制效果夏、冬两季无明显差别,整个循环冷却水处理水平较低,应进一步提高。
A method of platiculturewas developed to determine heterotrophic bacteria in industrial cooling water,and made a preliminary study on the growth control effect of heterotrophic bacteria.376 water samples were tested,119 test results are exceed standard level,the fraction rate is 31.65%.The test results between the summer and winter has no abviouse differency.The level to deal with in all system of industrial recycling water need to improve.
