[Scientific and Technological Achievements Promotion] Marine Purifier-Marine Oil Spill Purification Series Products
In recent years, reports of marine pollution have been frequently reported, and China has paid more and more attention to the protection of the marine environment. China is a large marine country, with a continental coastline of more than 18000 kilometers and an ocean area of nearly 3 million square kilometers. With the rapid development of marine economy, marine oil spill accidents occur frequently. After the leakage accident, the oil film floating on the surface of the water body will consume the dissolved oxygen in the water body and destroy the balance of the water ecosystem. At the same time, the organic matter in the oil film that is difficult to degrade will be absorbed by aquatic organisms, it will be enriched in aquatic organisms into the food chain and eventually endanger human health. At present, marine oil spill has become a major issue of concern to the world.
How to solve the urgent needs in the field of marine and river water pollution emergency disposal technology, the following small editor will introduce the core products of our institute's digital intelligent equipment research institute: expanded graphene high-efficiency adsorption products for oil spill and hazardous chemicals emergency disposal.
Marine environment and organisms polluted by oil spill
Before introducing our product
Let's first understand the current situation of oil spill disposal
After the oil spill accident occurs, the oil fence is first used to surround it to prevent it from spreading on the surface of the water body, and then the mechanical treatment method, chemical treatment method, bioremediation technology method, combustion treatment method, adsorption treatment method and other technologies are used to clean up the floating oil film on the surface of the water body.
Traditional adsorbent materials fall into two main categories:
(1) natural adsorption materials: sawdust, straw, chaff, feathers.
(2) Synthetic adsorption materials: polypropylene, polyurethane foam, oil-absorbing resin.
Synthetic adsorption materials have better adsorption performance than natural adsorption materials, but they still have obvious shortcomings in the adsorption process:
