Abstract
A field groundwater filtering sampling and moving-water flow index measuring device comprises a precipitation tank, an electrode measuring column of moving-water flow, a suction filter unit and a control unit; also provided is a measuring method by adopting the index measuring device. Sample filtering and electrode measuring work in the field groundwater sampling process can be integrally solved, sampling time point selection after well washing is scientifically and automatically achieved, and the sample filtering and collecting efficiency is remarkably improved; and meanwhile, the accuracy of testing various in-situ indexes such as pH value, oxidation reduction potential and the like in groundwater is remarkably improved in the design of moving-water flow electrode measurement. The method has good application prospect and value for carrying out groundwater monitoring and evaluation, remediation and governance, and the like.
