What are the common pollution sources in architectural decoration engineering?

1, the pollution caused by the initial decoration of the house. After the house is built, it usually needs simple initial decoration. Radon is the most harmful indoor environmental pollutant in the early stage of house decoration. Brick, lime, cement and other building materials mostly contain a certain amount of radioactive elements, which can easily release radon. At the same time, due to the different understanding levels of radon among the construction parties, some construction parties did not do a good job in radon monitoring during the geological exploration stage, and the indoor radon concentration increased greatly, especially in the basement, which seriously endangered the health of workers and residents.

2. Indoor decoration pollution. In the fine decoration stage, due to the requirements of building decoration, decoration materials containing harmful substances such as formaldehyde and benzene are often used in decoration projects, and the pollution concentration in this stage is much higher than that in the initial decoration stage. The concentration of each pollutant is influenced by different decorative materials. If the indoor equipment mostly uses blockboard, the indoor formaldehyde concentration is easy to exceed the standard; If natural stone is used for indoor decoration, indoor radon concentration will easily exceed the standard.

Control of environmental pollution in architectural decoration engineering;

1, insufficient control of decoration materials. It is very important to control the quality of materials in architectural decoration engineering. The quality of building decoration materials determines the quality of building engineering to a certain extent, which directly affects the health and even life safety of building decoration workers and house residents. In order to effectively ensure the quality of building decoration materials, not only the management and control of relevant state departments are needed, but also the conscious maintenance of material suppliers and constructors. Nowadays, counterfeit and shoddy products are constantly appearing in the market, which is not only the temptation of economic interests, but also the demand of the market to a certain extent. As far as building decoration materials are concerned, material certification and quality management can not completely eliminate market demand, but also provide a certain basis for local protection. In order to completely eliminate the use of polluting materials in architectural decoration engineering, the control of materials is the most important, and strict quality inspection should be carried out when materials enter the site.

2. Limitations of pollutant detection. At present, the monitoring of pollutants is usually carried out seven days after the completion of the decoration project, and most of them are detected at the construction site. Although the detection standard explains the detection method of pollutants, many detection equipment can not be applied in the field due to the limitation of conditions. However, the equipment and instruments that can complete the detection work in the construction site are not perfect, and the actual measurement accuracy cannot be achieved.

3. The rectification plan is difficult to implement. In the actual building decoration project, it is often after the house decoration is completed that the indicators are measured, and the measurement results obtained at this time are often unchangeable. Many householders have invested a lot of money in house decoration, and there is almost no possibility of rework after completion, unless the pollution is seriously exceeded. Therefore, even in the house decoration project, because some pollutants exceed the standard, only some measures can be taken afterwards, such as planting green plants, and the rectification plan is almost never put into practice.
