多泥沙水质自动监测站在黄河水资源保护中的应用

Application of sendiment-laden water quality automatic monitoring stations in water resources protection of the Yellow River

在黄河建设水质自动监测站面临诸多困难,需要重点研究多泥沙河流水质自动监测水样采集、样品前处理、系统远程监控等关键技术问题。黄河流域水资源保护局开发了带拦污栅的采样双体船和可吊装箱体,研制了具有故障自动报警和泥沙反冲洗功能的五级可调式水样前处理装置以及自动除藻装置、水下传感器自动冲洗装置、断水断电的自动保护装置等,引进了国外先进技术和设备,成功地建设了水质自动监测站。在黄河水量调度、引黄济津和突发性水污染事件中,自动站发挥了人工监测不可取代的作用,做到了对水污染抓得住、测得准、传得快。

During the construction of water quality automatic monitoring station in the Yellow River, we encounter many difficulties, such as key technical issues of sediment-laden water quality automatic collection, sample pre-treatment, remote controling system. Water resources Bureau of Yellow Water Conservancy Commission developed a twin-body boat with trash screen for sampling and overhang boxes, and other equipment of five-cascade adjustable water sampling pretreatment device with fault automatic alarm and sand backwashing functions, automatic algaecide and underwater sensor automatic washing devices, automatic protection installations for water and power break. Advanced technology and equipment were introduced from other countries for successfully building water quality automatic monitoring station. The automatic station has a unreplaceable role in water dispatching, water diversion operation and observing accidental pollution incident with fast speed, high accuracy and fast transformation.
