    • PROBLEM TO BE SOLVED: To provide a settling tank capable of massively treating wastewater or the like containing nitrogen-containing and/or sulfur-containing organic materials without diffusing malodor circumferentially.SOLUTION: The settling tank includes: a tank body 1 which is provided with a wastewater introduction port 11 and a supernatant fluid discharge port 12 and has an approximately cylindrical shape with an upper surface opening; a cover member 2 covering the upper surface opening of the tank body 1; a rotating shaft 3 provided along the central axis of the tank body 1 and having an upper part protruding from the cover member 2; the agitating blades 4 provided to the lower part of the rotating shaft 2; a roller 51 self-propelled along the upper end of the outer peripheral wall of the tank body 1; and an arm 5 connecting the roller 51 and the rotating shaft 3. By propelling the roller 51 for itself along the upper end of the outer peripheral wall of the tank body 1, the arm 5 is turned to rotate the rotating shaft 3, and the agitating blades 4 provided to the rotating shaft 3 are rotated.
    • 要解决的问题:提供一种能够大量处理含有含氮和/或含硫有机材料的废水等的沉降槽,而不会周向地扩散恶臭。 解决方案:沉淀池包括:罐体1,其设有废水引入口11和上清液排出口12,并具有大致圆筒形的上表面开口; 盖体1,其覆盖着罐体1的上表面开口; 沿着罐体1的中心轴线设置并具有从盖部件2突出的上部的旋转轴3; 设置在旋转轴2的下部的搅拌叶片4; 沿着罐体1的外周壁的上端自行推进的辊子51; 以及连接辊51和旋转轴3的臂5.通过沿着罐体1的外周壁的上端推动辊51自身,使臂5转动以使旋转轴3旋转, 设置在旋转轴3上的搅拌叶片4旋转。 版权所有(C)2013,JPO&INPIT
