小型移动式水站在环境监测中的应用及后续展望

Application and prospect of the small-scale water monitoring station

相比目前大量的站房式水质自动站,小型移动式水站具备占地小、投资少、站房可整体吊装灵活移动等特点,正成为水质自动监测网络的一个重要组成部分。小型移动式水站特别适用于城市内小型河流、景观河流和部分典型污染因子的河流。通过科学构建、合理组合,其优化的仪器设备和供电、采配水系统能满足水质实时监测监控、预警预报、评价考核等多方面工作。为拓展应用领域,小型移动式水站今后还应该进一步在研发组合式新仪器、优化仪器测试方法、降低设备能耗、提高国产化率等方面努力。

Compared with the fixed water quality monitoring stations that widely- used,the portable water monitoring stations are becoming important parts of online water quality monitoring system for their characteristics such as small space occupied,low cost,convenient of integral installation and mobility etc. They are especially appropriate for the monitoring of small inner city rivers,scenic rivers and the parts of river with typical pollution factors. Scientifically structured and well- organized portable stations with optimized power- supply and water sample collection and distribution system can fulfill different works of real time water quality monitoring,warning and forecasting,as well as appraisement. To broaden the applications of the portable stations,there is still more to be done in developing combined instruments,optimizing the testing method,reducing their energy consumption and ever- increasing the import substitution rate.
