Method and system for judging micro-plastic source in urban wetland environment, terminal and medium

Abstract

The invention belongs to the technical field of wetland protection, and discloses a method and a system for judging a micro-plastic source in an urban wetland environment, a terminal and a medium, and the method comprises the following steps: uniformly stirring water in a wetland by utilizing a sampling program; using the main control computer for controlling each module to operate normally; filtering the collected water sample by using a sample filtering program; centrifuging the solid substances injected into the centrifugal machine by using the centrifugal machine, removing residual water in the solid substances, and collecting the solid substances in the centrifugal machine; imaging under a micro-plastic microscope by using a microscopic image acquisition program to obtain a micro-plastic microscopic image; and determining the types of the micro-plastics with the same spectral information by using a micro-plastic type determination program to obtain the source of the micro-plastics. According to the invention, the microplastics in the water sample can be obtained; preliminary classification of the micro-plastics is realized through acquisition of the microscopic images of the micro-plastics, the operation is simple, effective judgment can be realized, and a way is provided for treatment of the micro-plastics in urban wetlands.

Description

technical field [0001] The invention belongs to the technical field of wetland protection, and in particular relates to a method, system, terminal and medium for determining the source of microplastics in an urban wetland environment. Background technique [0002] At present: Wetlands are lands and waters inundated with cups of water throughout the year or intermittently. They are the transition zone between terrestrial ecosystems and aquatic ecosystems and are a complex ecosystem. Plastics and their products have been widely used in industry, agriculture and daily life due to their lightness, good elasticity and durability. my country is the world's largest plastic producer and consumer, and it is the country that produces the most marine plastic waste. The widespread use of plastic products will inevitably cause a large amount of plastic waste to enter urban wetlands. Microplastics with a diameter of less than 5mm are new environmental pollutants that have attracted inte...

AI Technical Summary

Problems solved by technology

The monitoring of microplastics in my country is more concentrated in the ocean, and the monitoring data of microplastics in urban wetlands is still very scarce; and the monitoring of microplastics in urban wetlands has not been traced to the source, so it is difficult to control

[0003] Through the above analysis, the existing problems and defects of the existing technology are as follows: the monitoring of microplastics in my country is more concentrated in the ocean, and the monitoring data of microplastics in urban wetlands is still very scarce; and the monitoring of microplastics in urban wetlands does not carry out source tracing and, it is more difficult to manage
