A purification method for eliminating fine particle pollutants in coastal sea area

Abstract

The invention discloses a purification method for eliminating fine particle pollutants in near-coastal sea areas, which is set in the field of environmental treatment. The method comprises the following steps: throwing purification components in the waters of near-coast sea areas, and connecting adjacent purification components with connecting anchor ropes And on the land near the shore, there are fixed piles connected with the anchor ropes. The purification component includes a buoyant purification base. The purification base has a disc-shaped bottom plate. The first filter screen is set around, the bottom plate of the inner middle part of the cylindrical sleeve-shaped body is provided with a disc-shaped protrusion, the upper part of the disc-shaped protrusion is provided with a rotating base, and the disc-shaped protrusion and the middle part of the assembled disc Coaxial first flow holes are all provided. The invention realizes the automatic purification of nearshore water bodies, rapidly separates microplastic particles of different particle sizes in the water body and intercepts the microplastic particles for centralized treatment, and effectively improves the light transmittance of nearshore water layers.

Description

A kind of purification method for eliminating fine particle pollutants in coastal sea area technical field The invention belongs to the field of environmental management, be specifically related to a kind of purifying method that eliminates fine particle pollutants in near-shore sea area Law. Background technique [0002] "Microplastics", as the name suggests, are microscopic plastics. There is currently no precise definition of microplastics in academia, but Generally considered to be plastic fibers, particles or films with a particle size of less than 5mm, it is vividly referred to as "PM2.5" in the ocean. The important components of microplastics are represented by low-density polyethylene and high-density polyethylene. According to the particle size of microplastics, it can be divided into Large-scale microplastics and small-scale microplastics, relevant scholars have discovered through surveys of rivers, bays, islands and offshore waters around the world. Nowa...

AI Technical Summary

Problems solved by technology

[0003] Microplastics have a large specific surface area and hydrophobic properties, which can adsorb persistent organic pollutants and heavy metals such as PCBs, DDT, and polycyclic aromatic hydrocarbons in seawater. They are toxic to marine organisms and can enter the human body through the food chain, endangering Human health, and the near-coastal sea area is often the area where the aquaculture industry is developed. There are many microplastic particles in the water in such areas, which will lead to a large amount of microplastics in the aquaculture, which is not conducive to human health and consumption of aquaculture.
