Kind Code:
A1
Abstract:
A micro-plastic synchronous enrichment apparatus and method for a river. The apparatus comprises a filtration and collection unit, a sample point positioning unit and a sampling start and stop unit, wherein the filtration and collection unit is internally provided with stainless mesh steel rings (13), a plurality of groups of funnel-type micro-plastic filters (14) and sample collection bottles (15), and is used for rapid synchronous enrichment of micro-plastic samples of multiple sizes; the sample point positioning unit is composed of four positioning rods, and fixes the filtration and collection unit by means of hooks (5), which are arranged on traction ropes (1), and when the sample point positioning unit is used with fixed pulleys (4) and lifting control buttons (3), accurate positioning at different horizontal positions and vertical depths of a section is realized; and the sampling start and stop unit is used for controlling a time node of micro-plastic filtration and collection of a water sample, so as to realize the reliability and accuracy of sampling data.
