Many countries use "environmental labels" to indicate the environmental protection of products. An environmental label is a graphic mark that is printed or affixed to a product or its packaging. The environmental label indicates that the product not only meets the quality standards, but also meets the environmental protection requirements in the production, use, consumption and treatment process, and has no major damage to the ecological environment and human health.

This is Chinese.

Save electricity, conserve resources, and reduce pollution.

1 Try not to use disposable lunch boxes when eating out.

There are a lot of bai, now.

DU advocates green environmental protection in the country and reduces zhi

The emission of carbon dioxide DAO is a lifestyle with low energy volume, low consumption and low expense. Take the initiative to restrain yourself in life and improve your living habits. Do not waste, save.

Reduction of pollutant emissions in industry. Produce some energy-saving, environmentally friendly new materials.

1 Basic non-toxic and harmless type. It refers to the decoration materials that are natural, have no or very few toxic and harmful materials, and have only been simply processed without purification. Such as gypsum, talc, sand, wood, some natural stones, etc.

2. Low toxicity and low emission. It refers to the decoration data that has been processed and decomposed to grasp the accumulation and slow release of toxic and harmful substances, because of its subtle toxicity and does not pose a risk to human debilitation. For example, the formaldehyde release amount is low, and the large core board, plywood, fiberboard, etc.

3 Current scientific techniques and testing techniques do not allow for the identification and evaluation of the impact of their toxic substances. Such as environmentally friendly latex paint, environmentally friendly paint and other chemical decomposition materials. These materials are currently non-toxic and harmless, but with the development of scientific techniques, it will be possible to re-identify them in the future.

What are the current prevalent environmental protection decoration materials: 1 Environmental protection floor materials: grass planting pavement bricks are one of the various porous paving products, made of recycled high-density polyethylene.

It can increase storm runoff, increase surface water purification, and drain air water. It is mostly used in public equipment. 2 Eco-friendly wall materials:

The newly developed aerated concrete brickwork can be cut and formed with woodworking tools, masonry with a thin layer of mortar, and the appearance is powdered with special brushed pulp, which has the effect of heat resistance and energy storage. 3。Eco-friendly wall decorations:

Straw wallpaper, hemp wallpaper, gauze wallcovering and other products have a variety of functions such as moisturizing, insect repellent, and health care. The anti-mold wallpaper has been chemically solved to eliminate the mildew, foaming, and mildew growth that occurs when the air is moist or when the temperature difference between indoor and outdoor is large, and the appearance is soft and breathable. 4 Environmental protection materials:

Plastic-metal composite pipe is a high-tech product that replaces metal pipe, and its inner and outer layers are high-density polyethylene materials, and the two ends are aluminum, which has the excellent properties of plastic and metal, and is not rusty and purified. 5. Eco-friendly paint: bio-latex paint, in addition to easy construction, has a variety of colors, which can bring brilliant colors to the home.

After painting, it will emit a faint fragrance, and it can also be re-brushed or solved with a cleaning agent, which can restrain mold in the wall. 6. Environmental Lighting: This is a lighting system with the goal of thrifting electricity and protecting the environment.

Through scientific lighting design, the application of efficient, safe and high-quality lighting electrical products, to create a warm, economical and beneficial lighting environment. The concept of "light decoration and heavy decoration" can be said to be the same as the environmental protection career, and the rational use of waste items in the home life is also of great significance to create a low-carbon career environment. For example, use waste paper shells to make ashtrays, and throw them away at any time, which is trouble-free and inconvenient.

Remember to adopt it.

The raw materials of polystyrene particle light aggregate concrete blocks of Global BRICS Environmental Protection Technology Co., Ltd. are solid waste, construction waste and other wastes that need to be treated. The product can not only process waste in the production process and turn waste into treasure, but also has the function of thermal insulation, which can save energy and reduce emissions.

The current state of water resources in China.

1. Classification of water resources basins in China.

China is divided into ten major river basins according to river systems

Heilongjiang River Basin, Liaohe River Basin, Haihe River Basin, Yellow River Basin, Huaihe River Basin, Yangtze River Basin, Pearl River Basin, Southeast River Basin, Hainan River Basin, Inland River Basin.

2. Assessment of China's water resources.

In the early 80s of the 20th century, with the support of the Ministry of Water Resources, the first water resources assessment was carried out in the country, and according to the hydrometeorological data from 1956 to 1979, the national water resources were evaluated, and the results are shown in Tables 5 and 6.

1) Total precipitation. The average annual precipitation between 1956 and 1979 was trillions of cubic metres, equivalent to a depth of 648 mm, about 20 per cent below the global land average. Due to the influence of climate and topography, the regional distribution of precipitation is extremely uneven, decreasing from the southeast coast to the northwest inland.

The average annual precipitation in Taiwan Province is 2535 mm, while the average annual precipitation depth in the Tarim Basin and Qaidam Basin is less than 25 mm.

2) River runoff. In our country, about 56% of precipitation is returned to the air through evaporation from the land surface, and the remaining 44% is runoff. The national river runoff is trillions of cubic meters, and the equivalent runoff depth is 284mm.

Among them, the groundwater discharge is 678 billion cubic meters, accounting for about 27%; The recharge of glacial meltwater was 56 billion cubic meters, accounting for about 2%; About 17.2 billion cubic meters of water flowed from outside the country.

3) Soil water flux. According to the estimation of land surface evapotranspiration and groundwater discharge, the national soil water flux is about one trillion cubic meters (about 67% of the total precipitation), of which about 16% is recharged by gravity to the underground aquifer, and finally discharged by the river channel to form the river base flow, and the remaining trillion cubic meters are consumed by the evapotranspiration of soil and vegetation.

4) Groundwater resources. Groundwater resources refer to the total amount of groundwater recharge that is directly related to precipitation and surface water. According to the current situation of water resources development and utilization, the average amount of groundwater resources in China for many years is about 828.8 billion cubic meters, of which 676.2 billion cubic meters are distributed in hilly areas, 187.4 billion cubic meters are distributed in plain areas, and the repeated exchange between mountainous areas and plain areas is about 34.8 billion cubic meters.

5) Total water resources. After deducting the duplication of surface water and groundwater conversion, China's total water resources are trillions of cubic meters; Its 100.9 billion cubic meters of water more than river runoff is part of the amount of water recharged by precipitation and surface water in plains, mountain valleys and basins. In the absence of groundwater extraction, this amount of water is consumed in the form of submersible evaporation, and through groundwater extraction, a portion of the water can be harvested from the evaporation and utilized.

The average annual phreatic evaporation is 84.4 billion cubic meters in the northern plains and 11.9 billion cubic meters in the southern plains.
