摘要
在臭氧—生物活性炭深度处理技术的应用研究中发现,随着活性炭层中生物颗粒和非生物颗粒的积累,出水中的细菌数增多,并多与细小的活性炭颗粒一起流出,因此生物活性炭技术的应用也在一定程度上影响了饮用水的微生物安全性。针对可能存在的微生物安全性问题,通过生产性试验从浊度、颗粒数、颗粒物粒径分布以及细菌学指标等方面进行了系统分析。
The study on the application of ozone--BAC shows that： with the accumulation of bio-particles and non bio-pariticles, the germs in the effluent increase and most of them will flow out by adsorbing on the activated carbon, so the application of BAC will do harm to the drinking water safety in some degree. Aiming at the probably existing biological safety problems, systematic analysis on the turbidity, particles number, particle distribution and bacteriological indicators are carried out by production tests.
