- 摘要:
- 针对人工经验型碳源投加导致的浪费问题,设计开发了碳源投加智能控制系统,考察了碳源投加量与氮负荷变化及脱氮效果的关系。结果表明,改进型时间卷积网络能够有效捕捉变量间以及时间维度上的依赖关系,筛选出了以出水总氮、水温和过程硝态氮为主的关键因素,以此为框架构建了耦合“前馈补偿+定量核算+反馈调节”等过程的智能控制系统。在碳源投加智能控制系统应用后,达到了碳源投加泵流量与氮负荷呈正相关的目的,在出水总氮平均削减量同比提高15.7%、出水总氮浓度控制在7 mg/L以下概率达到96.7%的情况下,碳源平均投加量从218.4 g/m3下降至142.2 g/m3,降幅为34.9%。该碳源投加智能控制系统综合了进水、过程参数和出水水质,考虑了脱氮过程的各个阶段,克服了单一过程调控难以应对水质变化的难题,显著降低了运行药耗。
- Abstract:
- Addressing the waste carbon source addition issue caused by manual and empirical control, an intelligent control system had been designed and developed. Research had been conducted on the relationship between carbon source addition quantity and changes in nitrogen loading, denitrification efficiency. The results indicated that the improved convolution network could effectively capture the dependencies between variables and on the time dimension, and identified the main influencing factors as total nitrogen of effluent, water temperature, and process nitrate. Based on this framework, an intelligent control system centered around “feedforward compensation + quantitative accounting + feedback regulation” was constructed. After application of the intelligent control system, the objective of achieving a positive correlation between the flow rate of the carbon source pump and nitrogen loading was met. With a increase of 15.7% in the average reduction of total nitrogen in effluent and a probability of 96.7% for the total nitrogen in effluent to be controlled below 7 mg/L, the average carbon source dosage decreased from 218.4 g/m3 to 142.2 g/m3, with a decrease of 34.9%. The intelligent carbon source addition system established in this study integrates the influent, process parameters, and effluent, comprehensively consideres the various stages of denitrification process, and overcomes the difficulty of single process regulation in dealing with water quality changes,which significantly reduces carbon source consumption.
