查询词典 anaerobic

Through the test,the optimal hydraulic retention time was found to be within 6h～8h,NH3-N increasing rate,within 90%~96%,and a new phenomenon of anaerobic ammoniation was found.

采用ABR工艺对肉类加工废水进行前期氨化处理，通过试验得到最佳水力停留时间为6～8h，氨氮递增率在90%～196%之间；同时发现了厌氧氨氧化这一新现象；最后对氮素、pH等水质指标在氨化反应过程中的的转化规律进行了分析，以期为肉类加工废水的生物脱氮处理工艺提供一定的理论指导。

The experimental result of anaerobic ammoniation shows, the most appropriate hydraulic retention time is between six and eight hours, the longer the HRT , the higher the rate of NH3-N net increase.

现场调查分析表明，屠宰废水是一类富含有机氮的有机废水，其NH_3-N浓度在整个生物处理工艺过程中存在一定变化规律，特别在厌氧之后，NH3-N浓度将大幅增加(净增加70%—150%)，显然多数以进口NH_3-N指标进行硝化及反硝化的设计是错误的，且是导致NH_3-N难以达标的一个重要原因。

Anaerobe An organism that can live and grow in the absence of free oxygen, i.e.

厌氧生物：在缺氧条件下生存和生长的有机体，它们进行无氧呼吸(参见 anaerobic respiration)。

For example, a facultative anaerobe is an organism that can grow under anaerobic conditions but is also able to survive in aerobic conditions.

例如，兼性厌氧微生物就是既可以生长在厌氧条件下也可以在有氧条件下存活。

The results showed that:①The anaerobe and anaerobe facultative of anaerobic sewage liquid in summer were notablely significant more than that in spring.

结果表明：(1)夏季厌氧沼液中厌氧菌及兼性细菌数量均极显著高于春季；夏季好氧沼液中好氧菌数量显著高于春季。

The wet environment of soil also got more anaerobic in the long submersed time and promoted the utilization of soluble phosphorus by anaerobe and its transformation to OP, which explained the dramatically augment of OP in both land soil and drainage streams.

同时， 在周期较长的淹灌期间，土壤潮湿的厌氧环境增强，促进了厌氧微生物对溶解态磷的吸收利用，将其转变成有机态磷，因而在灌区土壤和排水中有机磷含量均有极显著的提高。
