Five different selective culture medium were used for sewage microorganisms directional isolated cultivate, advantage compound bacteria of photosynthetic bacteria, ammonifying bacteria, nitrifying bacteria, denitrifying bacteria and phosphate solubilizing bacteria could be gained through enrichment cultivate, then compounded them and used in test wastewater static treatment.

采用5种选择性培养基对水样中的微生物进行定向分离，通过富集培养，可以得到光合细菌、氨化菌、硝化菌、反硝化菌和磷细菌的优势菌群，进行复合后，再对试验污水进行静态处理。

The denitrification and methanogenesis are simultaneously conduced in the UASB reactor, and almost 100% denitrification has been achieved.

在单一UASB反应器内，发生了缺氧反硝化和厌氧产甲烷的双重生化反应，UASB反应器内获得了几乎100%的反硝化率。

The concentrations of NH+4-N,pH and NO-3-N first increased,but later they decreased smoothly. During the biodegradation process, AM was first hydrolyzed,then nitrified and denitrified,and the final products were oxidized into N2,CO2 and H2O.

不同时间段体系内NH+4-N、pH和NO-3-N都随着降解时间的增加逐步上升，但是达到一定时间后会下降，表明AM在降解过程中先水解，然后发生硝化反应，进而发生反硝化反应，最终AM降解成N2、CO2和H2O。

The mechanisms, main influencing factors and new available approaches of denitrifying dephosphatation were elaborated.

Steps of the invention are that an agitator in a main reaction region is started while water enters to implement the nitrification process under the hypoxic condition. When a maximum value appears on a pH value curve and an inflection point appears on an ORP curve, the stirring is stopped. When the last stirring stage is stopped, oxygen is added in the mixture for the degradation of organic compounds and the nitrification of nitrogen compounds. When a minimum value appears on the pH value curve, the aeration is stopped. The steps are repeated till the water inletting stage is finished. And an aerobic aeration stage is taken as an ending stage of a reaction period.

本发明步骤：进水同时开启主反应区搅拌器，进行缺氧条件下的反硝化过程，当pH值曲线上出现极大值且ORP曲线上出现拐点停止搅拌；上一搅拌阶段停止后，向混合液中供氧，进行有机物的降解和含氮化合物的硝化作用，当pH值曲线上出现极小值停止曝气；重复以上步骤，直到进水阶段结束，并以好氧曝气阶段为反应期的结尾阶段。
