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.
