Inactivation of microorganisms in MBR effluent by ultraviolet ( UV ) and the influence of photoreactivation and dark repair on it were studied .

考察了紫外线（UV）对MBR出水中微生物的灭活情况，以及光活化和暗修复对细菌灭活效果的影响。

Coli 's resistance to 5 μ g / ml streptomycin as index , the effect of photoreactivation on the mutation rate of E. coli with different dose UV radiation was compared .

coli对5μgml链霉素抗性突变率为指标，比较了不同剂量UV照射后光复活和暗处理对E。

When photoreactivation is not considered , all the bacteria , coliform group and fecal coliform group in MBR effluent could be inactivated with 17 mJ / cm2 of UV dose .

不考虑光活化的影响时，17mJ/cm2的UV剂量可以将污水中的细菌、大肠菌群和粪大肠菌群全部灭活。
