What is the connection between steel and environmental protection

Another benefit brought by the lightness of steel structures involves the foundation of buildings.

Obviously, when the overall weight of a building is reduced by half, the foundation of the building is also correspondingly lightened. Therefore, the demand for materials used in these foundations (mainly concrete) also decreases, and the excavation of foundations and the treatment of soil layers are correspondingly reduced, which also saves the use of land.

Personal safety is a significant topic in the housing construction and building industry, as complex scaffolding is used for high-altitude operations during construction, and the fall of objects from heights often leads to engineering accidents. The death rate at construction sites is much higher than the industrial average rate.

However, the steel structure process is different. Before installation, 80% of the work is carried out on the ground or in the factory, which is a good example to ensure safety.

2. What kinds of waste are produced in the steel industry

The steel industry discharges a large amount of waste gas, waste water and solid waste (such as slag) during production.

This not only wastes resources and energy, but also causes serious pollution to the environment and directly endangers people's health. At present, the main types of pollution in the steel industry are as follows: 1. Wastewater pollution.

The steel industry is a major water consumer, accounting for 19% of the national industrial water consumption and 11% of the national industrial wastewater discharge. 3%.

The wastewater from the steel industry contains a variety of pollutants, including a large amount of volatile phenols, fluorides, petroleum, suspended solids, arsenic, lead and other harmful substances. 2. Air pollution.

It refers to the situation where the concentration of pollutants in the air has reached a harmful level. Pollutants include solid, liquid, gaseous forms, lactic acid, and harmful gases, etc.

Air pollution has a significant impact on human health, plant growth and so on. The large-scale emission of sulfur dioxide can cause "acid rain", damage trees, slow down plant growth, and even lead to withering and leaf drop. 3. Steel slag pollution.

From mining, metal smelting to processing and manufacturing, waste residues are produced, such as waste rocks, tailings, smelting slag, dust, sludge, etc., all of which are solid wastes. The pollution of residues to the environment is caused through three pathways: the atmosphere, water and the solid wastes themselves. In addition to the aforementioned pollution, noise pollution in the steel industry cannot be ignored either. It can affect people's normal life, damage hearing, induce various diseases, reduce labor productivity, and even cause accidents.
