Wittgen takes you to understand environmental protection big country Germany
As everyone knows, Wirtgen brand from Germany, and Germany is the world's leading industrial countries, many engineering machinery well-known brands and brands from here, therefore, environmental issues here are very important to people. The following brand Wirtgen introduce you to Germany's environmental policy.
From northern Germany to the south, from mining to the countryside, the scenery is charming and the air is fresh. Without stop in the forest, open grassland, pollution-free wind power windmill and clear rivers flowing, embodies all caused by environmental protection and peaceful and quiet.
Industrial waste gas: install filters for chimneys
As early as 40 years ago, Germany began to control air pollution. From the end of the 70s of last century, Germany requires that power stations and waste incineration plants must filter their waste gas to reduce the content of nitrogen oxides and sulfur dioxide, and prevent the formation of acid rain, pollution of forest soil and other hazards.
Automotive exhaust: catalytic converters and environmental zones make breathing more comfortable
Urban air pollution not only comes from factories and power stations, but also increases the number of cars every year, which makes automobile exhaust become the main cause of air pollution. As early as 1973, catalytic converters designed for reducing emissions from automobiles were already on the market. Although it was not widely used until 1989, the effect was immediate, and the emission of toxic gases such as carbon monoxide and nitrogen oxides was significantly reduced.
Lead pollution: replacement of new water pipes to promote unleaded gasoline
The use of leaded gasoline and leaded drinking water can also pose a serious threat to people's health. In the 70s, the average level of blood lead in Germany was 140 milligrams per liter, which has now dropped to 50 milligrams per liter. Because blood lead levels exceed 100 milligrams per liter, it is likely to cause nervous system damage in children, so for the health of children, Germany pioneered the lead free gasoline and the replacement of lead-free water pipes. The promotion of unleaded gasoline is also 11 years ahead of europe.
Garbage disposal: champion of garbage recycling Germany
The details of Germany's detailed garbage classification system were introduced in detail. In early 1904, Germany began to implement the classification and collection of city garbage, people's life is rubbish must be classified, a kind of waste paper, food waste is a kind of waste glass, and is a kind of glass; which is divided into waste glass, yellow glass and green glass three, the formation of a garbage classification mature and reasonable system in Germany already.
River pollution control: the former smelly pond became today's swimming pool
For a long time, the river was once a shortcut for people to dump rubbish, and factories along the rivers discharged the untreated sewage directly into the rivers, causing serious pollution to the rivers. In 2000, a law enacted by the European Union greatly improved the water quality of European oceans, rivers and lakes. Today, such as the Elbe River has a large number of biological reproduction vitality, water disappeared again.
In 1992, scientists discovered that only 50 species of fish in the river Elbe in 2010, this number increased to 112. Extinct salmon also appeared in the Rhine in the early 50s. Those who have the opportunity to travel to Germany must not forget to take a look at the Rhine, and feel the water quality that is clear enough.
Also worth mentioning is that Germany attaches great importance to the city's green, everywhere you can see fine parks, buildings and transportation is circling back trees, flowers blooming like a piece of brocade Qing Huancui around, the whole city, such as the Greenwood garden in general.
As for the environmental protection of our country, we should learn a lot, although China's economy in the continuous development of environmental protection, but has a long way to go, I hope you can share.
