使硝化 meaning in English
nitrify
Examples
- The detection and application of nitrifying bacteria is limited by their peculiar ecophysiology such as strict autotrophic bacteria and slow growth
由于它们严格自养、生长缓慢的生态生理属性，使硝化细菌的检测和应用等受到限制。 - Chemolithoautotrophic nitrifying bacteria have many unfavorable physiological characteristics , namely , slow growth , small biomass and susceptible to environmental factors . to remove high ammonia - nitrogen concentration in wastewater from refineries , we directly enriched nitrifying bacteria of activated sludge via optimizing enrichment conditions ( temperature > phu nh4 + - n concentration ) . the results showed that the number of nitrifying bacteria after 6 weeks enrichment increased 32 . 8 times and nitrification rate improved 2 . 76 times than that before enrichment
实验结果表明，在ph7 . 7 8 . 5 、 28 ， 150rpm振荡暗培养的条件下，通过不断添加富集培养基，经过6周的培养后，可以使硝化细菌的数量增加32 . 8倍，硝化速率提高2 . 76倍，达到了富集的目的。
