Problems solved by technology

[0003] However, phytoplankton, zooplankton, and suspended particulates in large rivers are often mixed together, and the small-sized particles are the degradation of macromolecular organic matter in the upstream or along the coast, such as dead plants and animals. The particle sizes are all in a similar range (45 µm to 1000 µm), and the samples collected by traditional plankton nets are basically mixed together, making it difficult to further separate
[0004] At present, the existing methods for separating phytoplankton, zooplankton, and organic particles are very complicated and...

Embodiment 1

[0035] Example 1 Separation of plankton and particulate matter in Liuxi River-Pearl River water body

[0036] In this example, the collection and separation of plankton and suspended particulate matter in the water body from the lower reaches of the Liuxi River in Guangzhou to the Pearl River will be described. The sample points were selected according to the "Research Methods of Freshwater Plankton", and the sampling method was based on the requirements for sample collection of plankton and suspended particulate matter in "Water and Wastewater Monitoring and Analysis Methods (Fourth Edition)".

[0037] The operation steps are as follows:

[0038] S1. Put the water body mixed with plankton and suspended particles into static settlement, and collect the middle and lower layers of water containing particles and the near-surface water containing suspended plankton;

[0039]S2. add separation liquid to the near-surface water body containing suspended phytoplankton and plants coll...

Embodiment 2

[0049] Example 2 Collection and separation of plankton and particulate matter in the water body of Dashahe Reservoir

[0050] This embodiment is illustrated by collecting and separating plankton and suspended particulate matter in the water body in Dashahe Reservoir, Jiangmen City. The sample points were selected according to the "Research Methods of Freshwater Plankton", and the sampling method was based on the requirements for sample collection of plankton and suspended particulate matter in "Water and Wastewater Monitoring and Analysis Methods (Fourth Edition)". The specific operation process of collection and separation is the same as that in Example 1. Different from the section from Liuxi River to the Pearl River, there are fewer suspended particles in the water body of Dasha River Reservoir, and the density of phytoplankton (cyanophyta, chlorophyta) and zooplankton is higher. The collected high-density plankton is dark green, mainly Microcystis that caused a slight "bl...

Abstract

The invention discloses a method for separating particulate matters and plankton from a water body efficiently and quickly. According to the method, the plankton and suspended particulate matter samples are successfully subjected to a separating treatment operation, so that zooplankton, phytoplankton and the suspended particulate matters are continuously and effectively separated from the water body of a river in sequence. The method disclosed by the invention has the advantages of wide application range, simple operation, quickness and the like, and provides an important technical means for research on environmental ecology of a large-scale open water body.

Description

technical field [0001] The invention relates to the technical field of ecological research on plankton in river water bodies, and more particularly relates to a rapid separation method for plankton and plants in water bodies and its application in quantitative analysis. Background technique [0002] There is a predation relationship between plankton, and the predation effect of zooplankton on phytoplankton and particulate matter causes differences in trophic levels among the three, which will directly lead to the detection of isotopes, organic pollutants, and heavy metal residues. The detection results among plants, zooplankton and particulate matter will have large differences, for example, the fractionation of isotopes from high trophic level to low trophic level makes the nitrogen isotope value of zooplankton much higher than that of phytoplankton and particulate matter, while in organic matter dyeing detection Due to the bioaccumulation effect of different trophic levels...
