查询词典 ammonia nitrogen

The COD,ammonia nitrogen and turbidity of secondary effluent can be farther removed by aerated filter and the reclaimed water qualities are improved.

好气滤池同时具有普通滤池和曝气生物滤池的优点，能对二级出水中的COD、氨氮和浊度等指标进一步去除，提高再生水水质。

Aerobic filters have the advantages of both common filters and biological aerated filter. The COD, ammonia nitrogen and turbidity of secondary effluent can be farther removed by aerated filter and the reclaimed water qualities are improved.

The water quality was more stability when the dominant species was mainly Oocystis borgei in it. Ammonia nitrogen and nitrite nitrogen in the experiment pond was lower than that of the control pond.

波吉卵囊藻为主的微藻群落控制的水质较稳定，实验池氨氮和亚硝酸盐氮浓度较对照池低。

The result of the test showed that the fed quantity of TiO2 was 1.25 mg／mL,the photocatalytic degradation of the pyridine was in conformity with the first order kinetic equation,the feeding of 0.2％H2O2 obviously increased the degradation rate of the pyridine and the nitrogen in the pyridine converted into ammonia nitrogen;the pearlite-loaded TiO2 had the same catalytic effect as that of powered TiO2 and was easy to recover and reutilize.

以钛酸四丁酯水解法制备TiO2，采用溶胶一凝胶法在膨胀珍珠岩上负载TiO2，在UV-TiO2体系中对水中吡啶进行光催化降解，结果表明：TiO2加入量为1.25mg／mL，吡啶的光催化降解符合一级动力学方程，加入0.2％H2O2可明显加快吡啶的降解速度，吡啶中氮转化为氨氮，珍珠岩负载型TiO2与粉末TiO2具有相同的催化效能，且便于回收和重复使用。

But its return to original state product is mainly the ammonia nitrogen, but is not the ideal nitrogen.

Ammonia nitrogen and total nitrogen removal rates were enhanced to about 95% and 90%.

采用干湿投配的措施对总氮去除效果进行了强化。

The pH value of silages was all lower than 4.0 and the ratio of ammonia nitrogen to total nitrogen was all lower than 5.0, which improved the quality that all the silages in experiment were good.

经不同切碎方式的各组青贮饲料的有机酸含量均无显著差异（P〉0.05），pH值均在4.0以下，而且氨态氮与总氮的质量比也均在5.0以下，达到了优质青贮饲料的标准，虽然各青贮饲料的粗蛋白、粗灰分和可溶性碳水化合物含量有显著差异（P〈0.05），但均为优质的青贮饲料。

Results showed that there were no evident effects of different mechanical processes on the organic acid content(P＞0.05). The pH value of silages was all lower than 4.0 and the ratio of ammonia nitrogen to total nitrogen was all lower than 5.0, which improved the quality that all the silages in experiment were good. Though the effects of three different mechanical processes on the CP, CA and WSC contents of silages were evident, the silages were all excellent.

经不同切碎方式的各组青贮饲料的有机酸含量均无显著差异(P＞0.05)，pH值均在4.0以下，而且氨态氮与总氮的质量比也均在5.0以下，达到了优质青贮饲料的标准，虽然各青贮饲料的粗蛋白、粗灰分和可溶性碳水化合物含量有显著差异(P＜0.05)，但均为优质的青贮饲料。

After 5 months of ensiling,inoculating silage inoculant bacteria led to lower pH(P.05),lower ammonia nitrogen in total nitrogen(P.05) and content of butyric acid(P.01)compared to the untreated silages.

结果表明，青贮5个月后，添加青贮菌剂可以显著降低pH值(P＜0.05)、NH3/TN值(P＜0.05)，减少丁酸含量(P＜0.01)，有利于保存青贮物的营养成分，提高青贮品质。

The semi-aerobic landfill can eliminate the pollution of nitrogen in the landfill by means of its self-disposal function in a shorter period within the laboratory simulated conditions. This supplies an important idea and way for solution to the problems of high concentration of ammonia nitrogen being difficult to treat in leachate in the middle and final stages.
