针对地下水污染的“抽排-处理”方法，提出了基于ICT的知识信息管理修复技术。ICT的有用性进行了讨论，监测污染物和地下水位，传输数据之间的修复以及远程修复中心，以及控制修复以及决策支持分析。开发了一个原型系统，并应用于现场测量。原型系统可靠运行约600天。作为决策支持分析，模糊推理模型进行了讨论。根据简单可靠度理论确定了隶属函数。通过数值模拟评估了该方法的有效性。仿真结果表明，所提出的方法是可能减少泵送量相比，PID控制或工程师的经验知识。分析结果还显示了污染物的癌症风险和过量抽取地下水造成的地面沉降风险。
ICT-based remediation with knowledge information management is presented for the pump-and-treat method of contaminated groundwater. The usefulness of ICT is discussed for monitoring contaminants and groundwater level, transferring data between the remediation well and the remote remediation center, and decision support analysis for controlling the remediation well. A prototype system was developed and applied to field measurement. The prototype system performed reliably for ~600 days. As a decision support analysis, a fuzzy inference model is discussed. The membership functions were determined based on simple reliability theory. The effectiveness of the proposed method was assessed by numerical simulations. The simulation results suggest that the proposed method is likely to reduce the pumped quantity compared to PID control or an engineer’s empirical knowledge. Analysis results are also shown for cancer risks from contaminants and ground settlement risks due to excess pumping up of groundwater.
