Method and device for enhancing short-range nitrification and denitrification of wastewater through swirling autorotation

The invention relates to a method and a device for enhancing short-range nitrification and denitrification of wastewater through swirling autorotation. The invention provides the method for enhancingthe short-range nitrification and denitrification of the wastewater through the swirling autorotation. The method comprises the following steps: (A), performing swirling treatment to circulating mud-water mixed liquid reflowing in a biochemical tank; (B), performing swirling cracking on a suspended solid in coal chemical wastewater treatment tail water; (C), returning the tail water after swirlingcracking treatment in the step (B) to the biochemical tank for circulating degradation treatment. The invention further provides the device for enhancing the short-range nitrification and denitrification of the wastewater through the swirling autorotation. 本公开涉及旋流自转强化废水短程硝化反硝化的方法和装置，提供了一种旋流自转强化废水短程硝化反硝化的方法，该方法包括以下步骤：(A)旋流处理生化池中回流的循环泥水混合液；(B)旋流破解煤化工废水处理尾水中的固体悬浮物；以及(C)步骤(B)中经旋流破解处理的尾水返回至生化池循环降解处理。还提供了一种旋流自转强化废水短程硝化反硝化的装置。
