| abstract | (57) [Summary] [Problem] To enable online monitoring of Al ion concentration in acid-added returned sludge in coagulation solid-liquid separation of suspended water, and to always reduce the amount of acid-added returned sludge to an appropriate amount. Give them control. SOLUTION: An aluminum or iron-based inorganic coagulant is added to water containing a suspension to coagulate the water suspension, the flocculated floc is solid-liquid separated, and a mineral acid is added to at least a part of the separated sludge. In the coagulation / separation equipment for adding and dissolving the metal hydroxide and returning it to the water, SS To the acid solution from which was removed, an alkali agent was added to precipitate a metal hydroxide, and the turbidity of the deposited solution was measured optically. A coagulation solid-liquid separation facility comprising means for controlling the flow rate of a return pump. |
