- Abstract:
- To address the issue of evaluating flocculation settling performance, new parameters characterizing floc settling behavior were proposed, including floc settling ratio (FV), floc sludge concentration (FLSS), floc partition coefficient (FLD), and floc settling index (FVI), and the interrelationships among these parameters were derived. Furthermore, a matching online testing device was developed based on optical principles. The device is equipped with functions such as automatic sampling, automatic testing, periodic measurement, deep cleaning, and cyclic monitoring, with a measurement accuracy of 0.5%, meeting practical application requirements. Based on this device, the simultaneous determination and dynamic analysis of the above parameters were achieved, and a floc settling characterization model was established, providing multi-dimensional quantitative basis for flocculation process optimization. The device was applied in a power plant in Inner Mongolia to monitor the fitted parameters and real-time turbidity during operation. Through these parameters, the flocculation settling effect can be reflected in real time and the effluent turbidity can be predicted in advance. The device exhibits a certain monitoring and early warning function for the clarification system.
