【摘要】 采用BTB培养基与格利斯试剂检测相结合的改良方法,从养猪场废水中分离纯化出6株高效异养硝化反硝化菌株,其中,F3菌株脱氮性能最佳,NH+4-N和NO-3-N去除率分别为98%和99%。F3菌株在pH=8.0、38℃时,30~72 h进入快速生长期。F3菌株分别处理3种氨氮浓度不同的模拟废水A、B、C,培养3 d,F3菌株对NH+4-N去除率均达到93%以上;F3菌株分别处理3种不同来源的养猪场废水,降解NH+4-N效果在52%~78%。更多还原

【Abstract】 Used the improved method of BTB medium combined with Reagent detection,six high efficiency strains of heterotrophic nitrification and denitrification were isolated from pig farm wastewater. Among them,the strain F3 had the best nitrogen removal performance. The removal rates of NH+4-N and NO-3-N were 98%,99%,respectively. As pH 8. 0、the temperature of 38 ℃,the strain F3 was in the rapid growth period during 30 ~ 72 h. When the test of F3 strain treated simulated ammonia nitrogen wastewater A,B,C with three different concentration after three days,the removal rate of NH+4-N was more than 93%. When using F3 strain to treat from piggery wastewater three different sources,the degradation effect of NH+4-N was 52% ~ 78%.更多还原
