Based on them, the conditions of zeolite modifying by AlCl_3 was explored, the adsorption properties natural zeolite to ammonia nitrogen and adsorption effects of aluminum modified zeolite to phosphor in solution was researched, the existing form of ammonia nitrogen was investigated by cyclic voltammeter.

本文在对沸石的结构、沸石吸附动力学、热力学、沸石改性及其在废水处理中的应用等相关文献综述的基础上，探索了用AlCl_3溶液改性天然沸石的条件，考察了天然沸石和铝改性沸石对溶液中氨氮的吸附性能以及对溶液中总磷的吸附效果，以及用循环伏安法探讨了水体中氨氮的存在形式。

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。

The key part of this project is the application of high effective degradative microorganisms for aromatic hydrocarbons and nitrify bacteria for biological nitrogen removal in the treatment of recalcitrant industrial wastewater.

本项目的关键技术是将人工筛选的芳香族化合物降解菌和生物脱氮的硝化细菌应用于难降解的工业废水处理工程。技术特点是：可在去除难降解有机物的同时脱除高浓度的氨氮。

The results show that after adding RBW 0.5-2.5% bentonite, the highest removal of COD and Kjeldahl Nitrogen was 32% and 24%; after adding RWB 1~5% lime, the highest removal of COD and Kjeldahl Nitrogen was 34% and 40%.

结果表明按土水比添加0.5%~2.5%的膨润土处理后，废水中的COD和凯氏氮的最高去除率分别为32%和24%；添加1%~5%的生石灰处理后，废水中的COD和凯氏氮的最高去除率分别为34%和40%。

Coarse protein content of root continuously increased from 11 26% under CK treatment to 30 21% under N 5(900 kg·hm -2 ), showing that Rumex K 1 could deposit and regulate absorbed nitrogen and appeared resistent to nitrogen fertilization.

根的粗蛋白的含量由对照的1 1 2 6%增加到N5( 90 0kg·hm- 2 )的 3 0 2 1 %，表明酸模的根具有一定的储存和调控氮的能力，这可能是作物具有较强的耐氮性原因之一。

The result of the test shows: in the case of inexistence of chlorin ion, the effect of electrochemical oxidation of ammonia wastewater of the Ti/SnO_2-Sb_2O_3 electrode is better than the Ti/SnO_2-Sb_2O_3-CeO_2 electrodes,efficientry.When there exist 400mg/L chlorin ion,both have perfect effect.

对氨氮的电化学氧化去除试验表明，在不含氯离子的情况下，经过优化的Ti/SnO_2-Sb_2O_3电极的去除效果优于经过优化的Ti/SnO_2-Sb_2O_3-CeO_2电极，但效率不高；而在含有400mg/L氯离子情况下，二者对氨氮均有很好的去除效果。

Through the research of this paper, a conclusion can be drew: NaCl treatment raise the NH4＋-N removal ratio obviously by 18%, and is better than treating by heating, H2SO4, HCl and NaOH. The most reasonable concentration of NaCl is 0.8~1.0mol/L considering technical, economic and other factors synthetically; The best conditions of NaCl modifying is as follows : temperature 70~75℃, time 2.5hours, granularity ＜120mesh, volume/mass 25ml/g; As additive forming pores, activate carbon powder is a little better than charcoal powder, but the effect of both is much better than sawdust.

通过本论文的研究得出以下结论：NaCl改性能明显提高沸石对氨氮的去除效率，氨氮去除率提高了18%以上，其改性效果优于加热、H2SO4、HCl、NaOH等处理方法，综合考虑技术经济等因素的影响，取0.8～1.0mol/L为最合理的改性浓度；NaCl改性的最佳条件如下：温度70～75℃，时间2.5h，沸石粒径＜120目，体积质量比25ml/g；作为微孔沸石的造孔剂，活性炭粉略优于木炭粉，但二者的效果均比木屑好得多。

Furthermore, during the above synthetic studies, we also found sodium amalgam was a useful agent for reducing azide to amine, which was applicable for various alkyl and aryl azides bearing different functional groups.

另外，我们还对实验中意外发现的钠汞齐还原叠氮的反应进行了研究，考察了考察了带有不同官能团的叠氮化合物在此体系下的还原反应，取得了较好的结果，发展了一种新的还原叠氮的方法。

The results showed that two of the ball cactuses tested could growth well in solution culture , in which the growth rate was significantly higher than or equal to that in peatmoss culture. Among the four solution culture formulae , formula 4 had the highest biomass increment and uptake of N , P and Kfor Ferocactu horridus. The biomass of Echinopsis calochlora did not differ significantly among the four formulae , but significantly increased higher than medium culture. This study indicated that ball cactuses could grow well in nutrient solution culture.

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
