- Abstract:
- In conventional water treatment processes, coagulation and sedimentation is multi-parameter, nonlinear and large time-delay process. An intelligent coagulant dosing system is constructed by using machine vision technology and related AI algorithm during the coagulation stage in a large waterworks. The system adopts macro imaging and utilizes underwater cameras to capture the macro features of alum floc formed during the coagulation stage, and applies image recognition technology to quantify the alum floc features. At the same time, combined with segmented ensemble learning, multi- dimensional production parameters related to coagulation and sedimentation are introduced to establish an intelligent dosing algorithm model. And then a multi-parameter coagulant dosing automatic analysis and evaluation decision-making system is developed. The application of the waterworks shows that precise control of intelligent coagulants dosing can reduce coagulant consumption and save production cost.
