Protect the environment - for the future of Long Island

There is garbage everywhere in life, and garbage not only occupies the place, but also pollutes the environment and seriously endangers people's physical and mental health. Although there are garbage bins on the roadside, most people are reluctant to dump the garbage into the garbage bin, but they are littered everywhere.

I think that if Long Island wants to build an international holiday and leisure island, environmental protection should be placed first. In order to protect the environment and for our health, I think we should design a smart "environmental classified garbage bin".

Function 1: This kind of garbage bin is a sorting bin. Secondly, the biggest advantage of this kind of bin is smart. The bin is equipped with a computer chip. When someone dumps the garbage, the heat sensor installed in the bin is used. The lid on the trash can opens immediately, and when you throw it in, the smart chip inside it identifies recyclables and non-recyclables. This means that if you throw recyclables into a non-recyclable bin, it will automatically sort the trash. Computer chips also classify garbage.

Function 2: If you look closely, you will find two “compressors” on the wall of the barrel. It keeps the garbage pressed and shrinked, and the space occupied by the garbage is very small.

Function 3: If the classmates who dump the garbage are very short and can't touch the edge of the bucket, the “retreat” of the trash can can be shortened automatically, so that a short student can easily dump the garbage into the bucket.

Function 4: Where the sewage is flowing, the use of “environmental waste bins” is even greater! Put it in a place that is far from the water, plug in a pipe that goes straight into the water, press the button, the garbage bin is controlled by the computer, using the chemical principle, just like a magical magician, the dirty water and sewage are completely disinfected and filtered. Into pure water, flowing out of another tube for human reference. By that time, people will not have to take heart water and sewage everywhere.

With the "environmental sorting bins" people no longer have to worry about garbage and sewage. Look, the flowers are blooming everywhere and the trees are shaded. The place where the garbage is released can no longer see the flying mosquitoes; the odor of the pungent smell can no longer be heard; the passing pedestrians no longer have to lick their noses and frown. With this kind of trash can we will live in the world of birds and flowers...

We know that most of the domestic waste is organic waste and plastic waste. They burn and produce steam, which can drive car engines to generate electricity. In this way, every thousand tons of garbage can be burned, and 20,000 kWh can be obtained. After the remaining garbage residue is crushed, it is a good paving material by reheating 300 ° C in the boiler.

At this time, some special vehicles with organic and plastic garbage came over. How do these used cars tell if they are organic waste and plastic and use them accurately?

Because they have a light that can distinguish garbage, called "resolving light." When the light shines on the trash can, it can be distinguished whether it is organic waste and plastic waste. When shipped back, it can secrete a liquid called "decomposition liquid." This liquid kills all bacteria and pests. At the same time they kill, they can secrete a liquid called "protective liquid". In addition to killing bacteria and pests, this "protective liquid" can protect the remaining things from being melted.

Then there is outside the boiler room. Wearing a pair of special glasses, suddenly in addition to the factory building and chimney, the rest is dark. The professional told me: "The darker the air, the more pure the air, the lighter it means the more polluted." Looking at the chimney is the darkest part of the factory, taking off the glasses and wondering: "Why the air on the chimney Is it the purest?” In the past, ordinary factories emitted up to 500 million tons of particulate matter from factories every year. The particulate matter adsorbed many toxic and harmful substances, and the composition was very complicated. But this power station is very different. Install a mouth that can absorb waste every two meters on the chimney, called the smoking port. After the smoking port is put in place, all the waste is sucked in by the mouth, and then the mouth that filters the exhaust gas is called the filter port. It first kills the toxic substances and carcinogens contained in the exhaust gas, and then uses a kind of light to heat the particles to 3000 ° C, it becomes pure air.

Let us act, pick up the rubbish at the feet, throw it into the trash can not far away, let our mother of the earth reproduce the glory of the past! Let us create Long Island together to become an international holiday resort island!
