硝化菌

The invention is to carry out heterotrophic nitrifying phenomenon from the biology angle by screening heterotrophic nitrifying bacteria and the technology is the condition precedent to carry out short-range self-synchronous nitration and denitrification.

本发明的目的是采用筛选异养硝化菌的方法，从生物学角度实现异养硝化现象，该技术是实现短程同步硝化反硝化的先决条件。

Biological powdered activated carbon enhanced the growth of nitrifier by absorbed toxic or inhibitory substance.

生物活性炭吸附了对硝化菌产生毒性和抑制的物质、强化了硝化菌在炭表面的生长。

But, this kind of condition would only occurred when a great deal of nitrobacteria are added into the water.

1去氨硝化菌能将鱼类所排放的氨转成毒性较小的亚硝酸盐，而去亚硝酸硝化菌则负责将亚硝酸盐再转成毒性更小的硝酸盐，硝酸盐必须由换水的方式移除，像硝化细菌这类的细菌再作用时需要消耗水中的氧气所以也称好氧菌。

Nitrification is one of the most important step is the nitrogen cycle, this series of reactions are responsible for chemoautotrophic nitrobacteria, therefore the chemoautotrophic nitrobacteria play an important role in nitrogen cycle.

摘要 硝化作用为整个氮循环的必须步骤之一，这一连串的反应主要由自营性的硝化菌负责，因此，自营性硝化菌在氮循环中扮演著关键的角色。

The results indicate that excellent nitration of NH,-N need the sufficient removal of COD to prevent the restrain of toxicant on the nitrobacteria.

指出NH_3-N完全硝化的前提是废水中COD的充分降解，以消除有毒物质对硝化菌的抑制作用。

Because of the slow growth rate, that increases the contaminant opportunity by other micro organisms, for these reason it risen the difficulty of culturing and purifying the nitrobacteria, and limit the counting method.

因自营菌生长速度缓慢，造成遭受其他微生物污染的机率上升，所以更增加了硝化菌在培养及分离上的困难，以及计数上的限制，使得现今环境中硝化菌的实际数量及其计数方式仍存有许多争议。

According to those limitations, this study would like to use the molecular biology method to enumerate the nitrobacteria in the sample fast and precisely. We use fluorescent in situ hybridization method.

基於上述原因，本研究希望以分子生物学的方法快速且精确的计数样本中硝化菌的数量，所采用的方式为原位萤光杂合法（FISH； Fluorescent In Situ Hybridization），针对铵氧化菌与亚硝酸氧化菌的16S rDNA设计一段专一性的探针。

By immobilization of denitrifying bacterium on different kinds of carbon fibers, effect of surface oxygenic functional groups of modified carbon fiber on denitrifying bacterium was investigated.

通过对比各种碳纤维表面含氧官能团对反硝化菌的固着化实验，研究了碳纤维表面含氧官能团对反硝化菌固着化的影响。

By means of contrasted immobilization of denitrifying bacterium on several kinds of carbon fibers, the effect of physical and chemical characteristics such as specific surface area, precursor and recycle, especially the surface oxygenic functional group on these carbon fibers was investigated.

通过对比反硝化菌在不同基体碳纤维表面的固着化及碳纤维表面含氧官能团对菌种的固着化实验，研究了碳纤维(基体、比表面积、循环利用性等)特性，尤其表面含氧官能团对反硝化菌固着化的影响。

The nitrobacteria were elutriated from PAOs (phosphate accumulating organisms) and proliferated within the BAF because of the short 8 days'SRT of SBR.

根据PAOs(phosphate accumulating organisms)和硝化菌在泥龄上的差异，采用8d的泥龄，在SBR反应器中逐步将硝化菌淘洗出去。
