    • Rotating biological contactor-type sewage treatment equipment of the present invention comprises a treatment tank 4 for storing sewage to be treated, a rotation shaft 3 which extends across opposed side walls 4a, 4b of the treatment tank 4, a plurality of rotating discs 1 mounted at a predetermined interval on the rotation shaft 3 in such a manner that each disc is partly submerged in the sewage stored in the treatment tank 4, and a driving means for supplying a driving force to the rotation shaft 3 in order to rotate the rotating discs 1. This equipment treats sewage by rotating the rotating discs 1 on which aerobic bacteria are attached, thereby allowing the aerobic bacteria to contact the sewage and aerobically decompose pollutants in the sewage. Each of the rotating discs 1 is composed of n portions of sector-shaped segments 11, wherein n is an integer not less than 1, and each of the sector-shaped segments 11 is composed of two equally divided sector-shaped pieces 11a, 11b. Each of the sector-shaped pieces 11a, 11b has thin elements 19a, 19b which form square grid-like meshes 191 of the same size, except in the neighborhood of a periphery surrounding each sector-shaped piece 11a, 11b; and the thin elements 19a, 19b extend vertically and horizontally relative to one side of each sector-shaped piece 11a, 11b, with crossing each other.
    • 本发明的旋转式生物接触器式污水处理设备包括:用于储存待处理污水的处理槽4,延伸穿过处理槽4的相对侧壁4a,4b延伸的旋转轴3;多个旋转盘1, 在旋转轴3上以预定的间隔,使得每个盘部分地浸没在存储在处理槽4中的污水中;以及驱动装置,用于向旋转轴3提供驱动力,以便旋转旋转盘 1.这种设备通过旋转附着好氧细菌的旋转盘1来处理污水,从而使需氧细菌接触污水并对污水中的污染物进行有氧分解。 每个旋转盘1由扇形段11的n个部分组成,其中n是不小于1的整数,并且每个扇形段11由两个等分的扇形块11a,11b组成 。 每个扇形片11a,11b具有除了围绕每个扇形片11a,11b周围的周围的相同尺寸的方格栅格状网格191的薄元件19a,19b; 并且薄元件19a,19b相对于每个扇形片11a,11b的一侧相互垂直和水平地延伸。
