For improving wastewater quality, one of the dare of steelworks is reducing cyanide in wastewater of gas washing treatment of blast furnaces. Costs of existing treatments, stringent environmental regulations and changeable composition of water from gas treatment, have led to study how available treatments can be modified and to examine new ones. Ozonation is one of cyanide treatments, tested within a European project. A process model was set up with Aspen Plus®, to assess operating conditions and wastewater distinctive characteristics and to demonstrate treatment robustness. Process was modeled by theoretical reactors, taking into account all more affecting reactions. A genetic algorithm was exploited to find kinetic parameters of these reactions. After validation, the model was used to analyse scenarios, by considering also real contexts. Pilot tests were extended, process knowledge was enhanced and suggestions were obtained. To promote cyanide removal with ozone, temperature and pH values were 30°C and 10, respectively. With an ozone (mg/h)/water (L/h) ratio of 100 mg/L, batch mode ensure reaching cyanide regulation limit (0.2 mg/L) after maximum 4.5 h, if initial amount was less than 20 mg/L. Higher removal was obtained than in continuous mode due to constraints related to this last run. Higher wastewater contamination needed further time and more ozone.

工业过程多目标优化研究因算法和设备的不完善,已经大幅限制了工业过程的智能化发展。为了提升流程工业过程的操作水平,本文提出了一种基于云服务平台和分布式系统的混合智能优化框架。在这个智能优化系统中,工业实时数据首先暂存于本地服务器,经过清洗整理后上传至云数据库中;然后在可拓展的云平台上部署分布式系统用于运行智能优化算法;最后将基于深度学习和进化算法的多目标混合优化算法打包上传至云计算平台。通过将多目标优化服务运行于数字孪生云上工厂,钢铁厂高炉铁水产量增加了83.91 t·d﹣1,焦炭比降低了13.50 kg·t﹣1,硅含量平均降低了0.047%。
