The invention is to carry out heterotrophic nitrifying phenomenon from the biology angle by screening heterotrophic nitrifying bacteria and the technology is the condition precedent to carry out short-range self-synchronous nitration and denitrification.

本发明的目的是采用筛选异养硝化菌的方法，从生物学角度实现异养硝化现象，该技术是实现短程同步硝化反硝化的先决条件。

At the end of this paper, the factors which influence the shortcut denitrification was discussed.

本文最后还对影响短程反硝化的因素作了讨论。

The results showed that DO is one of the most important controlling parameters for realizing shortened simultaneous nitrification and denitrification.

试验结果表明，溶解氧浓度是实现短程同步硝化反硝化的一个重要控制参数。

It is obvious that decreasing the temperature had more effect on nitrification than on denitrification in this short-cut system.

Finally, two short-path distillation processes and one falling film evaporator are applied in the regeneration of waste lubricating oil. In the test, the diesel oil, gasoline and lubricating oil are distilled respectively, while the gelatinoid materials, asphaltene and carbon residue remain in the draft. The regenerative lubricating oil accords with the standards of base oil. And the recovery efficiency is up to 75 percent. The technology used in the test doesnt comprise processes like pickling and alkali neutralization, which would cause secondary pollution like acid draff and sulfur dioxide and so on. As a result of this, our technology is friendly to the environment.

最后，利用一级薄膜蒸发和两级短程蒸馏工艺对废润滑油进行了再生回收工业应用试验，将柴油、汽油等轻油以及润滑油馏分分别蒸馏出来，而大部分胶质、沥青质、碳垢存在于残渣中，试验得到的再生润滑油符合基础油的标准，回收率达到75％，达到废润滑油再生的目的；同时再生过程中没有酸洗、碱中和等工序，不产生酸渣、二氧化硫等二次污染，是一种清洁环保的废润滑油再生工艺。
