摘要:
从活性污泥中驯化、筛选并分离出1株能有效去除氨氮的菌株LX 1-3,经过形态学与分子生物学鉴定该菌株为副球菌属(Paracouccus sp),NCBI GenBank登录号为MH156598.对该菌株进行反硝化性能测试,结果表明该菌培养的最适条件为30 ℃,最适pH值为7.0～7.3,48 h后脱氮率为30.7%.将该菌与1株高耐盐季也蒙毕赤酵母(KX447139)搭配,脱氮效率有显著提高.在好氧条件下,按照好氧反硝化菌与高效耐盐菌1:1的接菌量配比接入污水中,30 ℃反应48 h后,氨氮去除率为86.36%.该研究为提高污水脱氮处理效率提供了有效的方法.
Abstract:
Aerobic denitrifying bacteria has unique advantages in denitrification,which can be used to denitrify wastewater.In this paper,aerobic denitrifying bacteria has been isolated from activated sludge,it can effectively remove ammonia nitrogen called LX 1-3.Through identification of morphology and molecular biology,the strain is identified as Paracoccus sp,an accession number of NCBI GenBank is MH156598.Further studies showed that the optimum condition for the strain growth and aerobic denitrification is temperature 30 ℃,and pH value is between 7.0 and 7.3,its nitrogen removal rate can reach 30.7% after 24 h.Combination of this strain with a known high-lying,salt-tolerant strain significantly increases nitrogen removal efficiency.Under aerobic conditions,the 1:1 ratio of aerobic denitrifying bacteria to highly saline-tolerant Meyerozymaguilliermondii is added to the sewage.After 48 h of reaction at 30 ℃,the ammonia nitrogen removal rate is as high as 86.36%.This study provides a more effective method for improving the efficiency of denitrification treatment of wastewater.
