In the process of building construction, we will produce some harmful substances which cause certain pollution to the indoor environment. What are the indoor environmental pollutants in civil construction projects?
The prevention and control of building pollution mainly includes the following three aspects:
First, material selection. Proper selection of engineering materials is an important part of affecting indoor environmental quality. The selection of environmental protection materials and low-level radioactive materials requires the inspection certificate of the state and relevant departments and environmental protection marks. Otherwise, no matter what means or methods are adopted later, it is difficult to eliminate harmful substances.
Second, construction methods. The selection of construction methods is generally determined by the selected materials, but the construction methods of each material and the auxiliary materials used in construction are also different. For example, wallpaper has self-adhesive, white latex, organic glue and so on. Various construction methods are also related to the basic condition of the building. Of course, the price is also different. If the environmental requirements are high, organic glue should be used.
Third, construction time. Generally, the requirements of interior decoration time are not strict. In fact, whether in the South or in the north, the different seasons and humidity of decoration construction have a great impact on the finished decoration products. Some normal temperature construction technology will take measures because of low or high temperature, such as adding auxiliary materials to meet the construction quality, invisibly will increase the use of non-environmental protection materials.
In the process of civil construction, in order to prevent and control the indoor environment of civil construction projects, from the point of protecting people's health or public interests, it is necessary to strengthen the management of civil construction projects, which must be based on technical standards and economic rationality, so as to ensure the principle of safety and applicability, and formulate corresponding norms. Strengthen implementation.
