中文摘要：

采用静态试验对自养硝化污泥的除磷特性进行研究.分别提供氨、无机碳源和氨、无机碳源三种营养条件,考察了厌氧-好氧交替环境下硝化细菌摄取磷酸盐的情况.结果表明：在与聚磷菌的运行模式相对应的条件下,硝化污泥无除磷效果;通过染色观察,硝化细菌体内几乎没有PHB颗粒及异染颗粒;按照传统聚磷菌除磷模式培养的硝化细菌未表现出明显的除磷特性.论文从能量利用、营养类型及培养条件等方面对该现象和产生的原因进行了分析.

英文摘要：

The phosphorus uptake by autotrophic nitrifying bacteria was studied.The nitrifying bacteria phosphorus uptake ability discussed was fed with different nutrient with ammonia,inorganic carbon and ammonia,inorganic carbon when cultured under anaerobic/aerobic condition.Results indicated that in the condition similar to EBPR of phosphate accumulating organisms,phosphorus could not be removed by the nitrifying bacteria.Cell dyeing displayed that they had no PHB granules or poly-P granules.The nitrifying bacteria had no clear phosphorus removal ability cultured in the traditional mode of phosphorus removal of phosphate accumulating bacteria.The phenomenon and the reasons caused by energy utilization,nutritional type and culture conditions were discussed.
