| titleOfInvention | Wastewater coagulation sedimentation method |
| abstract | Addition of a flocculant and / or a neutralizing agent that measures the concentration of each ion in wastewater containing phosphate ions and / or sulfate ions and reacts with each ion to form a precipitate based on the measurement result By controlling the amount, we provide a method for coagulating and precipitating wastewater that can minimize the amount of flocculant and / or neutralizing agent used and the amount of sludge generated, and stably maintain the quality of the treated water. To do. SOLUTION: The pH of water to be treated is adjusted to two predetermined levels, and an aqueous solution containing barium ions is added to the water to be treated at two points adjusted in pH to form a suspension in which an insoluble barium salt is formed, Measure the physical quantity that is the concentration index of the suspension at the two points, and use the slope of the calibration curve prepared for water with known ion concentration as a coefficient, and the binary simultaneous equations with each ion concentration in the treated water as unknown The amount of each coagulant and / or neutralizing agent that forms a precipitate by reacting with phosphate ions and / or sulfate ions according to the obtained ion concentration is obtained by solving A method of coagulating sedimentation treatment of waste water.
