摘要:
沉淀池作为除浊首选工艺设备，通过自然沉淀或者混凝沉淀去除水中多种杂质，但因其自动化程度低、人工操作工作量大的特点，运行效果往往差强人意。采用AI图像识别技术将水体中的矾花特征进行计算、分析、分类、转化，实现混凝剂烧杯最佳加药量试验在线化、水体矾花特性（粒径、数量）全流程监测和泥位高度可视化控制，结合沉淀池构（建）筑物水力条件优化，实现智能调整沉淀池运行状态。研究及应用结果表明，通过沉淀池整体优化智能控制体系调整能够大幅提升处理能力，降低出水浊度，减少药剂投加量，降低下游膜设备的污堵风险，降低膜系统的清洗频率，对提高水处理车间的产水量、产水品质均有促进作用。
Abstract:
As the preferred process equipment for turbidity removal, sedimentation tanks remove various impurities from water through natural sedimentation or coagulation sedimentation. However, due to their low degree of automation and heavy manual operation workload, the operating effect is often unsatisfactory. AI image recognition technology is used to calculate, analyze, classify, and convert the characteristics of alum flocs in water body, achieving online testing of the optimal coagulant dosage, full process monitoring of alum floc characteristics (particle size and quantity) in water, and visual control of sludge level. Combined with the hydraulic condition optimization of sedimentation tank structures, intelligent adjustment of sedimentation tank operation status is achieved. The research and application results show that the overall optimization and adjustment of the sedimentation tank through the intelligent control system can effectively improve the treatment capacity, reduce the turbidity of the effluent, the dosage of chemicals, the risk of fouling and blockage of downstream membrane equipment, the cleaning frequency of the membrane system, while promote the production and quality of water in the water treatment workshop.
