硝化细菌

The gravel does this by both removing dissolved solids and providing a place for the nitrifying bacteria to convert into plant nutrients.

在这是否都去除水中的固体物质和提供一个地方的硝化细菌转化成碎石植物养分。

The different fractions of cell death of nitrifying bacteria in the two systems could be caused by different microbial compositions in the SBR and BNR systems.

两种系统中硝化细菌由细胞死亡引起的衰减比例不同是由于两种系统中不同微生物组成所致。

The results were as follows. At the temperature of 25~30C,initial pH value of 7.5~8.0,alkalinity of NaHCO3 concentration 1700mg/L, NH4+-N concentration of 150mg/L,aerations of 110rpm, cultured 24h,immobilized nitrite bacteria N4s NH4+-N removal efficiency reached 99.47%,accumulative volume of NO2--N was 116.65mg/L.

试验结果表明：固定化亚硝化细菌N_4在温度25～30℃，起始pH值7.5～8.0，摇瓶转速110rpm，碱度为NaHCO_3浓度1700mg／L，初始NH_4~+-N浓度150mg／L，培养24h，NH_4~+-N去除率达99.47％，NO_2~--N积累量达116.65mg／L。

The results indicated that paraquat had a significant effect on soil microflora in thirty days. Paraquat of 0.05~5mg/kg inhibited the growth of funguses, but stimulated the growth of the population of cellulose utilizing microorganism and nitrifying bacteria. The low-density paraquat stimulated the growth of bacteria and actinomyces, but high-density paraquat inhibited their growth.

结果表明，施用百草枯对土壤微生物有明显的影响。0.05~5mg/kg的百草枯在施药后30d内，真菌种群严重被抑制；硝化细菌种群和纤维素分解菌种群均呈刺激效应；低浓度的百草枯刺激土壤细菌和放线菌种群的生长，而高浓度的百草枯则抑制其生长。

High percentages of ammonia or hydrogen sulfide are oxidized on the first half of the column. The oxidation of high amounts of hydrogen sulfide would involve some environmental stress on nitrifying bacterial growth and activity.2002 Elsevier Science Ltd. All rights reserved.

高百分比的氨或硫化氢在第有个柱的一半上被氧化，大量的硫化氢的氧化作用会使硝化细菌的繁殖和活性更加适应环境的压力。

In the redox zones bacterial community structure changed,and the preponderant bacteria were sulfate reduction bacteria,iron reduction bacteria,nitrate reduction bacteriacorrespondingly,however there were other bacteria in the redox zones.

各带中生物群落结构发生了明显的变化，相应地以硫酸盐还原菌、铁还原菌和反硝化细菌为优势菌群，同时也存在其他作用的细菌。

Through boring and gathering water in natural reed wetland, the concentration of three kinds of nitrogen (nitrate-N, nitrite-N and ammonia-N) and the quantities of denitrifying bacteria in the soil of different depths were sampled and analyzed in the bloom period of reeds.

在芦苇生长旺盛阶段（3-5月），在芦苇湿地钻孔，聚水，取样分析了水中三氮含量及水孔不同深度土壤中反硝化细菌的数量。

Finally, 20 strains aerobic denitrifying bacteria, which have higher denitrification efficiency, are isolated from the activated sludge, and the further research for the 3 strains out of the 20 are carried cot.

从完成驯化的污泥中筛选出20株具有较高脱氮效率的好氧反硝化细菌，并对其中的3株FW3、FW6和FR4进行了进一步的研究。

To investigate the responding behavior of denitrifying bacteria to different carbon source (i.e. methanol, ethanol, sodium acetate, sodium propionate, glucose, domestic wastewater and endogenous carbon source), several batch experiments using the sludge from the Carrousel oxidation ditch were carried out at 15.4℃±0.8℃.

为了研究低温环境下反硝化细菌对各种碳源的直接反应，利用Carrousel氧化沟系统的活性污泥，以甲醇、乙醇、乙酸钠、丙酸钠、葡萄糖、生活污水及内源物质为碳源，在15.4℃±0.8℃低温状态下开展序批式缺氧反硝化试验。
