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。
