Field sampling method for surface water

Abstract

The invention discloses a field sampling method for surface water. The field sampling method comprises the following steps of 1, dividing a field sampling operation region into a plurality of operation sub-regions; 2, arranging a safety pile, and placing a sampling device in each operation sub-region; 3, enabling a first sampler to carry out sign-in and photographing operation, enabling a second sampler to carry out water sample collection and other operations, and then performing sedimentation and centrifugation; 4, enabling the first sampler to detect a pH value, dissolved oxygen and the like of a water sample, and enabling the second sampler to carry out heavy metal suction filtration operation and other operations; putting the water sample into a plurality of sampling bottles; and 5, enabling the first sampler to add a fixing agent into the sampling bottles and perform character description; enabling the second sampler to perform bottle opening plastic packaging operation, and perform counting-boxing and box-sealing strip-pasting operations; and then, enabling the first sampler to upload related data. The field sampling method provided by the invention can effectively reduce misoperations, and has the outstanding advantages of being clear in sampling process, intuitive and effective, high in efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of surface water sampling, and more specifically, the invention relates to an on-site sampling method for surface water. Background technique [0002] At present, the separation of collection and measurement means that the collection, analysis and testing of cross-section water samples to be assessed are assigned to different units, so as to change the current territorial monitoring model and link up with stakeholders from a mechanism. After the unified implementation plan is formulated, the third-party organization will sample according to the unified technical specifications, encrypt and mix the water samples and randomly distribute them to various analysis laboratories. The analysis laboratories will analyze the water samples, and the original monitoring data will be directly transmitted to the monitoring station. After completing the data summary review, share it with local governments in a timely manner...

Problems solved by technology

[0006] In order to solve the problems existing in the existing on-site collection process, such as over-reliance on the experience of the samplers, poor tacit understanding between the samplers, low work efficiency, and long sampling time, the invention provides an innovative on-site sampling method for surface water, from The on-site sampling process is optimized from the two dimensions of space and time, and the division of responsibilities between the two samplers is clearly defined as operations related to the software APP and operations related to water sample collection, so that the samplers can efficiently divide and collaborate, and the on-site Reasonable distribution of equipment and instruments can effectively solve many problems in the existing technology
