查询词典 sludge

The results showed that the percentage of ammonia oxidizing bacteria and nitrite oxidizing bacteria in the activated sludge was 15.7%±3.7% and 12.9%±3.2%, Nitrosomonas europaea-Nitrosococcus mobilis lineage were the dominant AOB, Nitrobacter spp.

结果表明，污泥中氨氧化菌的含量为15.7%±3.7%，优势菌属为Nitrosomonas europaea-Nitrosococcus mobilis；亚硝酸氧化菌的含量为12.9%±3.2%，优势菌属为Nitrobacter spp。。

Nitrobacter can gradually acclimate to nitrous nitrifying conditions and refreshed, so the sludge should acclimation and the nitrite accumulation disappear.

Nitrosobacteria was selectively cultivated on the biofilm and short-cut nitrification was achieved in 4 weeks by controlling the following conditions as HRT=1 d, DO=0.5—1.0 mg·L-1, pH of about 7.5, T =30℃ and no sludge recycle.

结果表明，在控制HRT=1 d、温度30℃、DO=0.5～1.0 mg·L-1、pH=7.5左右、无污泥回流等条件下，经过4周的运行，成功地选择培养出亚硝化型生物膜，实现了短程硝化。

According to the above study result, the diversity of microorganisms population in the SUFR system is complex and the bio-community formed in the SUFR system is stable. The close relations between abundance of bacteria and nutrients were found. The correlation between heterotrophic bacteria and COD was 0.949. The correlation between organic phosphate bacteria and TP was 0.815. The correlation between nitrosobacteria and NH3-N was 0.909. The correlation between disnitrifier bacteria and TN was 0.653. These inneglectable great factors effecting on phosphorus-uptake and phosphorus-release of phosphorus accumulating organisms are the influent COD、the concentration of DO、the sludge retention time、the temperature. The diversity of organic phosphate bacteria population in the SUFR reactor was complex and there is no phosphate bacteria taking the absolute superiority in quantity. The near-native pure culture method powerfully complement the traditional pure culture technique and enrich culture technique. The sludgy bioactivity is very good in whole SUFR reactor. By the quality of being biochemistry, the anaerobic phase is higher than anoxic phase and the anoxic phase is higher than aerobic phase of SUFR.

通过以上试验内容研究发现，SUFR 系统中的微型动物种群较多，微生物生态系统稳定；系统中微生物的数量与营养盐的含量密切相关，其中总异养菌与COD的相关系数r 为0.949，有机磷细菌与TP 的相关系数r 为0.815，亚硝化菌与NH4+-N的相关系数r 为0.909，反硝化菌的数量和TN 的相关系数r 为0.653；污水生物除磷工艺中进水COD 的浓度、DO 浓度、泥龄的长短、温度都是影响聚磷菌释磷及吸磷效果的不可忽视的因素；SUFR 系统中的磷细菌呈现种群多样化的趋势，没有占绝对优势数量的磷细菌；微孔滤膜近自然培养法是对传统纯培养技术和富集培养技术的有力补充；整个SUFR 反应器系统中污泥的生物活性很好，就可生化性来讲，厌氧反应器大于缺氧反应器大于好氧反应器；按照动力学方程式求出的细胞生长动力学特征值和SUFR 脱氮除磷系统工艺的实测值结果基本吻合。

An ammonia-oxidizing bacterial strain A5 was isolated from the activated sludge of A/O process,and identified as Nitrosomonas sp.

从厌氧好氧工艺的废水处理系统活性污泥中分离出亚硝化细菌A5 ，鉴定为亚硝化单胞菌 Nitrosomonassp。

The sludge age in the reactor is large, so that nitrobacteria and nitrosomonas live together. The nitrogen removal via nitrite was possible mainly because the activity of nitrobacteria was inhibited rather than rushed out in number.

反应器内的污泥龄较长，硝酸菌和亚硝酸菌长期共存，发生短程硝化反硝化主要因为硝酸菌的活性受到抑制，而不是数量上受到淘汰。
