The result for British voters elected to leave the European Union(EU) has been announced today, which will have far-reaching repercussions both domestically and internationally, and immediately plunged the 28-member political and economic union into its worst crisis since it was founded.
The vote result was at times bitter and acrimonious. The Leave campaign, headed by former London Mayor Boris Johnson, took 51.9% of the vote to the 48.1% that the Remain campaign, headed by Prime Minister David Cameron. According to British Broadcasting Corporation, 72% of the electorate voted.
The result had an immediate effect on the financial markets, with the pound plunging to a 30-year low against the US dollar and the Euro, Europe’s single currency, slid 3% against the US currency. The US has for years had British membership of the EU a core part of its European policy, while the UK and China are experiencing what Cameron and President Xi labeled “a golden era” after the Britain last Oct., when deals worth 40 billion sterling were announced. Now the referendum result to leave the EU is affecting the gold market greatly, which will lead the gold price to a increasing tendency apparently. It is said that gold, as a favorable hedge investment, will be more and more popular by the investors, which will push the gold price moving up.

Recently, the Ministry of Environmental Protection decided to organize the steel and coal industry sewage charges levied special inspection work. This work will be carried out in violation of state regulations approved pay reduction, or postponement of the sewage charges or exemption from sewage charges will be according to the law and the State Treasury does not fulfill management responsibilities sewage charges levied competent environmental protection department staff carrying out checks, if the circumstances are serious, someone shall be given administrative sanctions according to the law; and if constitutes a crime, someone shall be held criminally responsible according to the law.
It is understood that, this time of the inspection, the sewage charges levied situations of the sulfur dioxide, nitrogen oxides, dust, soot and other pollutants of the steel and coal industry are the focus. This time, if the company which is found to be necessary to collect the sewage charges during the inspection, but actually don’t; or the actual emissions are clearly incompatible with the approved emissions, then the on-site verification should be carried out, and relative evidence shall be collected, and to re-approve the emissions, re-collect sewage charges. Furthermore, the state requires all localities use this opportunity of special inspection to re-establish and account the discharging pollutants’ types and quantities of the steel and coal industry of their own administrative area, and effectively improve the collection rate of the sewage fee.
From a macro look, this time, China is taking the "real thing", and really determining to deal with the problem of pollution of sulfur dioxide, nitrogen oxides, thus, tungsten trioxide denitration catalyst at this juncture will have excellent prospects. In industrial, the currently widely used of denitration process is SCR technology, which the core technology is the denitration catalyst. This catalyst takes vanadium pentoxide as the main active component, titanium dioxide as the carrier, and tungsten trioxide as the additive to play the role of anti-sulfide, anti-sintering of the carrier. Tungsten trioxide denitration catalyst is known as the most widely used SCR catalyst with the relatively high efficiency of denitration and the most stable performance, therefore, it has very extensive application on the flue gas denitration of the steel industry and coal-fired plants. In addition, tungsten trioxide is also often involved in the production hydrodesulfurization catalyst, as a main active material to performance an efficacious effect.

With the more stringent standards of Chinese air pollution regulations, the next 5--10 years will be the key period for Chinese air pollution control, the growth rate of market capacity will continue to maintain of around 10%. Statistics show that, in 2015 China's air pollution control industry scale was over 130 billion RMB, of which about 18.7 billion RMB belongs to desulfurization industrial, the scale of denitration industrial was about 75 billion RMB, industrial scale of dust removal was about 430 billion RMB. In 2014, the thermal power industry desulfurization market size was 168 billion RMB, building materials, chemicals, nonferrous metals, petrochemical, and other non-thermal power desulphurization industry market size was about 54 billion RMB.
Judging from the emission source of sulfur, China mainly emissions the sulfur dioxide, "2015--2020 of China desulphurization industry market supply and demand forecasting and market special research report" showed that the Chinese sulfur dioxide emissions was 20.439 million tons, which reduced by 3.5% compared to the previous year. At present, the desulphurization business is mainly directly expanded to the industries of thermal power plants, steel and cement ect.. China currently has nearly 80% of the electric power is coming from thermal power which takes coal as the raw material, large amounts of harmful gases (such as sulfur dioxide, nitrogen oxides, etc.) discharged into the atmosphere through the chimney, causing the pollution of the surrounding environment, resulting in human respiratory diseases and crop failures, etc. .
Desulfurization and denitrification technology is the best way now available to effectively control sulfur dioxide and nitrogen oxides and other harmful gases, in which desulfurization catalyst is used as a core technology in desulfurization technology. The surface of tungsten trioxide desulfurization catalyst has tension, which can reduce the surface tension of the limestone slurry and the radius of the critical nucleus, thereby strengthening the bisulfite to be oxidized and to precipitate gypsum, thus to realize reducing emissions. Hydrodesulfurization catalyst is presently the most widely used in this industry, which is added the mainly active components of tungsten trioxide, cobalt oxide ect., and aluminum oxide as the carriers, and then prepared by drying and calcining; it plays an extremely important role in industrial gas desulfurization, diesel cracking, gasoline hydrotreating and other areas, therefore, tungsten trioxide catalyst desulfurization market will continue to expand.

On June 23rd, the fourteenth session of the Shanghai Municipal People's Congress of the thirtieth session "(Revised Draft) Shanghai Environmental Protection Ordinance" for the water pollution problem, the Committee believed that, at presently the phenomenon of secretly pouring and discharging of the production waste-water in the shipping out is quite serious, and seriously affecting the safety of drinking water. People can not live without water, the production waste-water directly discharge may not only cause groundwater pollution, but also cause serious soil pollution. In view of the current Shanghai sewage pipe network construction is quite completely, the forbidden on the production waste water treatment by shipping out has practice feasible.
Recently, with the soil pollution around schools and other news was broken, soil pollution has already caused public concern. Soil pollution can be divided into two categories of inorganic and organic pollutants. Inorganic pollutants include acids, alkalis, heavy metals, and radioactive elements; organic pollution is mainly organic pesticides, petroleum and urban sewage, sludge and so on. Compared to the atmosphere, water pollution, the soil problem has the properties of hidden, hysteresis, accumulation, regional and irreversibility, therefore, its governance is difficult, and requires a long term. However, I think the key in the soil pollution is the prevention, what is to say the source control. Production and domestic waste water, sludge and other emissions are the major cause of soil pollution.
Tungsten trioxide has a narrow band gap, can effectively respond to visible light; as a photocatalyst, it can be used to treat the polluted water which contains organic and inorganic pollutants. Studies have shown that the photocatalytic of tungsten trioxide photocatalyst can solve the problem of pollution chromium, mercury, lead and other heavy metals; moreover, it also plays an extremely high utility in COD removal and organic matter degradation of the polluted water.

According to E20 Institute survey shows that, in the end of 2015, China has 607.6 million rural population, more than 2.7 million distributed in natural villages, the annual generated polluted water has amounted to about 10 billion tons. Because the village polluted water treatment facilities has the problems of ubiquitous network construction imperfect and low levels, so the rural polluted water treatment rate is still less than 10%, which means that there are still a large number of untreated polluted water random emissions. When you walk through the village enough, you will find that most of the village even has no garbage, let alone what the polluted water treatment facilities; moreover, most of the villagers believe that it is enough to discharge the polluted water and other rubbishes directly into the river and just flow them away, no more action is excess? Furthermore, this concept is widespread in the village areas. Thus, compared to the current more than 90 percent of urban polluted water treatment rate, the countryside polluted water treatment works has a long way to go; it not only requires the government pay attention to it, and strengthen the construction of infrastructure, but also, the vast and most long-term project is to deeply root the environmental protection concept in the hearts of every citizen.
Column on behalf of the processing capacity (unit: cubic meters/day), line graph on behalf of the number of plant
Experiments using photocatalyst under light conditions, to carry out photocatalytic degradation of the life wastewater, and found that due to the COD concentration domestic polluted water are low, therefore, nano photocatalyst is more suitable for processing. Tungsten trioxide photocatalyst has been shown in using for degrading organic pollutants, and play a good effect, include: degradation of pesticides, bleaching treatment, water purification and so on. Furthermore, as a catalyst, the tungsten trioxide photocatalyst itself is not consumed, and can be long-term viability.
The crystal structure of the tungsten trioxide is monoclinic, the photocatalytic activity caused in this state has a good effect on the responsive of visible light, and being a good performance of the photocatalyst. In particular, nano tungsten trioxide because of its large specific surface area, the surface effect is remarkable, is a good catalyst, either can be suggested as the primary catalyst, but also as the co-catalyst, and has a high selectivity on the reaction.
