World’s first! Our country has invented a graphene photocatalytic mesh that can restore stinky sewers to clarity in just half a month

With the rapid advancement of technology today, while it brings convenience to our lives, it also has irreversible effects on our environment. The green hills and clear waters of childhood have long been replaced by sewage ditches and high-rise buildings. These sewage ditches are not only unsightly but also deadly to aquatic life and can contaminate drinking water sources, which causes great concern for people. As a result, researchers from the Jiangsu branch of the China Academy of Science and Technology invented a graphene photocatalytic mesh. By placing this mesh in sewage ditches, the water can be purified within just a few days, restoring it to a clean state. Is that hard to believe? It is understood that its base material is just an ordinary polypropylene woven mesh; its ability to purify wastewater comes from the addition of materials such as graphene, photosensitive substances, and quantum materials to this mesh
Just visible light is sufficient to break down harmful substances in water, produce oxygen through water splitting, restore the water source’s self-purification ability, and make polluted water clean again. It is worth mentioning that experiments have shown that the graphene photocatalytic mesh is eco-friendly and reusable; it is the only product in the world currently capable of being used for large-scale water treatment, and it has successfully passed **-level certification
After the graphene photocatalytic mesh is installed, aerobic microorganisms in the water will gradually grow over time, consuming the excess nutrients present in the water. In about a week, the water quality will gradually return to clarity, without the need for any additional energy sources, chemical agents, or microbial strains. Today, graphene photocatalytic nets have been successfully installed in polluted water sources in areas such as Jiangyin and Dongying
Pollution control is the key at the source; we cannot follow the old path of polluting first and then dealing with it. . .
It’s probably not related to graphene, except for the word “graphene” itself. First it was nanomaterials, then functional polymer materials; now it’s graphene. Because by using trendy new terms, it’s easier to deceive people or make money, and it’s also easier to get those who don’t understand the situation to pay for so-called \"smart\" products.
I feel the same way; in a city in Jiangsu, the whole city is made of graphene – those foreigners are really ridiculous! I didn’t know that Chinese people have already integrated graphene into their daily lives! https://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1927781 (Source: Haichuan Chemical Industry Forum Website)
