SS SVI Real-time control system of weighted coagulation additives using measured value of SS and SVI

摘要

The present invention relates to a weighted coagulant real-time control system using SS and SVI measurement values. The present invention is able to inject an optimized weighted coagulant by determining the type and dosage of the weighted coagulant from the SS and SVI of raw water in a bioreaction tank and the SS value of discharged water, and reduce maintenance costs by recycling the injected weighted coagulant. The present invention includes: a first SS measurement device which is included in the bioreaction tank and measures the SS of raw water in the bioreaction tank; an SVI measurement device which is included in the bioreaction tank and measures the SVI of raw water in the bioreaction tank; a sedimentation basin which receives raw water from the bioreaction tank and precipitates sludge; a second SS measurement device which measures the SS of supernatant water discharged from the sedimentation basin; a weighted coagulant injection device which is included in a raw water inlet path of the sedimentation basin and the bioreactor, and supplies and mixes the weighted coagulant to raw water; and a control unit which determines the type and dosage of the weighted coagulant by receiving measurement values in real time from the first SS measurement device, the second SS measurement device, and the SVI measurement device.
