Description

一种阻水透气间歇曝气的模块式人工湿地 技术领域
本发明涉及人工湿地技术领域，具体地说涉及一种阻水透气间歇曝气的模块式人工湿地。

在一实施例中，所述驱动块2044的截面呈平行四边形，两个所述插块2043的一侧分别呈倾斜状且分别与所述驱动块2044的两个倾斜面相接触，且两个插块2043还分别与所述驱动块2044通过连杆2046滑动铰接。这样设计，通过简单倾斜面以及连杆2046的设计实现同步滑动效果，结构巧妙且制作简单。
在一实施例中，所述螺纹杆9的螺纹呈两段分布，且位于上方的螺纹螺距大于位于下方的螺纹螺距。这样设计，使得螺纹杆9转动时，第三料框301上移的距离大，避免由于重力，第三料框301结构下沉贴于第二料框201，使得第二料框201也下沉，使得需要转动螺纹杆9圈数较多才能实现第二料框201沿水平方向的自由滑动。
在一实施例中，所述模块架7内还设置有输出端与一个所述螺纹杆9相连接的电机11，且两个所述螺纹杆9上均还设置有皮带轮12，两个所述皮带轮12间还连接有皮带13。这样设计，通过电机11、皮带轮12以及皮带13的配合，实现两个螺纹杆9同步转动，使得第三料框301以及第二料框201上升以及下降稳定。

2.通过设置透气阻水层5以及隔气层6，将夹持在两层之间由曝气管4产生氧气锁住以及将好氧反应区内的污水锁住，进一步增强了污水在好氧反应区1内的硝化反应以及其他有机物去除反应；
3.通过增强硝化反应、其他好氧异氧菌的其他去除有机物的反应以及反硝 化反应降低了污水内含氮污染物的浓度，避免了污水内含氮污染物浓度较高导致湿地植物根系腐烂的情况发生，即增强了植物根系的活性，由于植物根系可将一部分含磷污染物吸收和同化，故也增强了除磷效果；
4.通过设置自下而上出水，实现硝化反应、反硝化反应以及植物净化依次有序进行，确保每个区间可完全被污水覆盖进行反应，提高湿地利用率；
