摘要
针对F-A-20 T/H压差式全自动净水装置絮凝沉淀过程中进水浊度波动与药剂投加量难以精确控制等问题,提出基于数字孪生的预测控制方法,通过构建包含进水口(DN10)、排泥口(DN65)、放净口(DN65)与出水口(DN25)的完整数字孪生模型,实现从原水浊度1000 mg/L到出水浊度100 NTU的全流程预测控制。结果表明,该方法使絮凝剂投加精度提升,反冲洗周期从80~100 min优化至最佳值,实现了净水装置的智能化运行。
To address issues such as fluctuations in influent turbidity and difficulties in precisely controlling chemical dosing during the flocculation and sedimentation process of the F-A-20 T/H differential pressure-type fully automatic water purification device,a predictive control method based on digital twin is proposed.By constructing a complete digital twin model that includes an influent port(DN10),a sludge discharge port(DN65),a drain port(DN65),and an effluent port(DN25),full-process predictive control is achieved from raw water turbidity of 1000 mg/L to effluent turbidity of 100 NTU.The results show that this method improves the dosing accuracy of flocculants,optimizes the backwash cycle from the range of 80 minutes to 100 minutes to an optimal value,and enables intelligent operation of the water purification device.
