It bring forward that semi-aerobic can accelerate degradation velocity of COD and ammoniac nitrogen and promote the stabilization process of landfill , which also affords technic guidance for accelerating landfill stabilization and leachate self-purity .

初步揭示了准好氧填埋垃圾降解的基本机理，分析了影响垃圾体降解的因素，为今后准好氧填埋技术的深入研究和工程应用提供理论基础和技术支持，并为厌氧填埋场的改造提供思路。

As for the wastewater containing organic nitrogen, thebest approach of ammoniation should be anaerobic ammoniation.

对含有机氮的废水，其最佳氨化途径为厌氧氨化。

In the process of anaerobic ammoniation, NO3" is always in the rather lower level , and meanwhile NO2" can never be found.

厌氧氨化过程中NO_3始终处于较低水平，而NO_2则始终未检出。

In comparison, the period of aerobic ammoniation is shorter and NH3-N peak value is lower (the rate of net increase can reach 33 % only).

厌氧氨化时间较长，氨化彻底，NH_3-N峰值高(净增率可达196%)，而好氧氨化时间短，峰值低(净增率仅33%)。

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。

Water quality indexes in the course of ammoniation reaction was analysed to provide theoretical guiding for the biological denitrification of meat processing wastewater .

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。

It was discovered that when optimal HRT for anaerobic ammoniation of slaughter wastewater was 6～8h,NH3-N net increasing rate ranged within 90%～196%;the anaerobic ammoniation was in the form of the first class reaction;according to this,the present authors first e.

试验发现，屠宰加工废水厌氧氨化最佳水力停留时间为6～8h，NH3-N净增加率在90%～196%之间。

The results indicate that, with HRT of 8?h and temperature of 35℃, the COD removal rate is beyond 80%, the removal rate of TN about 8%, the ammonification rate of organic nitrat.

试验表明：厌氧附着膜膨胀床反应器处理乳品废水，在水力停留时间为8h、中温35℃条件下，COD去处率达到80%以上，对总氮的去除约为8%，出水有机氮的氨化率达70%以上，ρ/ρ由进水的0 5提高到0 8以上。
