摘　　要：采用3株高效耐盐菌对模拟兰州石化废水进行处理,探讨了废水处理前后pH值、BOD5等的变化,同时考察了营养物质的添加对COD去除率的影响。结果表明,处理后废水pH值下降,BOD5大幅升高,且高效耐盐菌在3%含盐量下的COD去除率可达80%以上,外加碳源对COD去除率影响较小。3株高效耐盐菌均从自然界中分离获得,初步鉴定为食酸菌属(Acidovorax)。Three high effective halotolerant strains were used to treat petro-chemical industrial wastewater.The changes of various indexes such as pH value,BOD5 before and after treatment were discussed,and the effect of adding nutrients on COD removal rate was investigated.The results showed that after the treatment,the pH value decreased and BOD5 significantly increased,and under the condition of 3% salinity,the COD removal rate was above 80%.Additional carbon source had little effect on COD removal rate.Three strains were separated from nature,and they were identified as Acidovorax.
