On June 28, Beijing started the public welfare activity of "Reduce haze in Action", and released the five sub-activities of the whole people common revise "Three Character Classic of Green Life" and so on. However, the most striking is that the Netherlands haze purification tower which once set off red-hot in the circle of friends is expected to be introduced to China in July, and begin to handle haze in Beijing at the beginning of September. It is reported that this haze purification tower which is up to 6.5 meters is inspired by the Beijing haze, it can absorb 75 to 80% or more of the haze in the air; and each 30,000 cubic meters of air purification only needs to consume 30 watt of electricity with safety and energy saving. Interestingly, the inventor was whimsy, he collects the gray haze and then makes it a ring by compressed the carbon into a black gem, which is really turning waste into treasure!

Beijing haze is the most serious area of China, since the haze was put on the issue, it has been cause for many concern. In June, the Ministry of Environmental Protection released the air quality during April and May of Beijing, Tianjin, the Yangtze River Delta, Pearl River Delta region and the overall country's; data shows, PM2.5 concentration decreased year on year in Beijing, which is a good performance.

 

Haze governance is an important part of air purification, nitrogen oxides and sulfur oxides are a major source of air pollution. Since China is a country of coal energy sources, coal burning flue gas desulfurization and denitration projects have become the key of environmental protection. At present, the most commonly used of denitrification project is SCR technology, and it takes WO₃ denitration catalyst as the core part, which accounts for about 30% of the denitration system investments. The activity of WO₃ denitration catalyst played a direct impact on SCR denitration efficiency, and WO₃ is mainly playing the supporting role of anti vulcanization, anti-toxic, anti-sintering of carrier ect. in the denitration catalyst, existing as a catalyst promoter. With the ongoing in-depth and transformation of denitration projects, as well as the improving of the denitration catalyst, WO₃ will play an increasingly high effectiveness in SCR systems.
