The influence of organic loading, hydraulic loading, the ratio of gas and water and the height of filling to removal efficiency of COD, ammonic nitrogen and total nitrogen has been studied in BAF by using the self-confected wastewater.

中文摘要：本文以自配生活污水为实验用水，研究了有机负荷、水力负荷、气水比以及填料高度对BAF去除COD、氨氮、总氮的影响，并在沸石吸附饱和后对其进行生物再生。

Better denitrification efficiency could be obtained with adding amylo and the removal ratios of ammonia nitrogen were at least 93%. The removal ratio of TN increased gradually with the increasing of C/N ratio. When C/N ratio was 10, the best removal ratio of TN could reach 80.81%. But when C/N ratio added on 12, the ratio removal of TN was not increased only keeping about 75%.

投加淀粉调整C/N比，系统能取得良好的脱氮效果，氨氮的去除率均在93%以上，随着C/N比的增加，TN的去除率也逐渐的增大，当C/N为10时，TN最高去除率能达到80.81%，但当C/N增大到12时，TN的去除率不再增大，只是稳定在75%左右。

After comparison of various process, a optimum process—ANIS process can be drawn; A autotrophic denitrifying process is successfully started up and stable operated; ANIS nitrous nitrifying process and autotrophic denitrifying process are joining-up in series to operate, and sound nitrogen removal effect can be achieved.

本论文广泛研究了各类C/N均小于1、甚至低至0.5以下的低、中、高氨氮浓度废水进行亚硝化处理的效果，综合比较了各种不同的处理工艺，得出了最佳工艺——ANIS工艺和运行条件；成功启动并稳定运行了自养反亚硝化系统，并将ANIS亚硝化工艺和自养反亚硝化工艺串连运行，取得了良好的脱氮效果。

The research results showed that the growth of Nitrobacter always depended on the conversion of ammonia-nitrogen to nitrite-nitrogen by Nitrosomonas under both no aeration and aeration.

研究结果表明，在无曝气条件下和曝气条件下，填料上硝酸盐细菌的生长均依赖于亚硝酸盐细菌转化氨氮为亚硝酸盐氮的过程。

The effect of PPC preoxidation on nitrification was conducted by measuring the quantity of nitrite bacteria and nitrate bacteria ,nitrosification performance and nitrification performance in the BAC process.

结果表明，高锰酸盐预氧化后的生物活性炭与单独生物活性炭上亚硝酸菌和硝酸菌的分布具有相同规律；但高锰酸盐预氧化后生物活性炭工艺中亚硝酸菌和硝酸菌数量、亚硝化速度及硝化速度都要高于单独的生物活性炭，这是高锰酸盐促进后续生物活性炭工艺去除氨氮和亚硝酸盐氮的主要原因

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
