The Application Analysis Of Pollution Permits In The Environmental Management Of Fire Power Industry

Thermal power are an important force in China’s power industry,however,in the economic development at the same time,thermal power production also caused serious pollution to the ecological environment,the power plant emissions has become one of the major industrial pollution sources in our country.With deepening of electric power market reform and the change of government function,strengthen the supervision of power plant pollution is inevitable trend,is also the important measures to realize energy conservation and emissions reduction thermal power production.Since reform and opening-up,our country gradually perfect thermal emission regulation,from regulatory basis and the way of regulatory agencies and regulatory perspective,thermal pollution regulatory system preliminary established.But due to institutional defects still exist some problems,including laws and regulations and emission standard is not scientific,the imperfection of the mechanism of collaboration between regulators and supervision way unreasonable use,etc.To implement the control of pollutants emission permits system implementation plan requirements,accelerate the implementation of control of pollutants emission permits,environmental protection department issued a "discharge permit management interim provisions".The regulations is the national sewage discharge permission management first normative documents,according to the environmental protection act,the law on the prevention and control of water pollution the law on the prevention and control of atmospheric pollution"administrative licensing law" and other laws and the requirements of the "implementation plan",from national level the tradable permits management regulations,it is mainly used for guiding the current across the discharge permit issued by the application,such as work,is to realize the 2020 emission permits covering all important support of stationary sources,at the same time,countries establish pollution permission regulations lay the foundation for the next step.The emission permits the "one proof’ management in the management object,time period and content.We can effectively implement the "three simultaneous" system of the construction project required by the environmental protection law.A large thermal power industry pollutant emissions,and has a good base for environmental management,also representative pollutant characteristics,in the first plays an effective emission permits issued by the work of the pilot.1 x 350 mw supercritical unit with dragon coal comprehensive utilization of low calorific value of coal construction project cogeneration,for example,choose low calorific value of coal,coal ratio of coal gangue,coal washing,coal slime 5:4:1,coal for design 154.8 × 104 t/a,checking types of coal is 164.67 x 104 t/a,coal design sulfur coal,coal quality checkout 0.19%and 0.20%,52.11%52.11%design coal ash content of coal,coal quality checkout.It is calculated that the pollutant discharge will be the design of sulfur dioxide,the design of coal,523.03 t/a,the school nuclear coal quality 585.70 t/a,and the nitrogen oxide design the coal quality 572.58 t/a,the school nuclear coal quality 575.61 t/a.The limestone-gypsum wet flue gas desulfurization,achieve the desulfurization efficiency of 90%or more,the bag filter for dust removal in colleges and universities,to reach 99.92%or higher dust removal efficiency,with low nitrogen combustion technology and the method of SCR flue gas denitration technology of flue gas denitration,reach the denitration efficiency of 70%or higher.Chemical water treatment of wastewater using method and application principle of reverse osmosis treatment,acid and alkali neutralization process,etc.,so that when the sewage treatment can be used for dust suppression or ash humidification,green or road spraying,etc.Based on the project allows the discharge of sulfur dioxide emissions 523.03 t/a,smoke emissions of nox emissions by 572.58 t/a,162.62 t/a,and other useful information,during the reporting platform for commissioning,complete discharge permit application is provided,and for other enterprises and institutions to apply for discharge permit to demonstrate.Discharge permit is new management mode,can replace the existing environmental protection acceptance,for the environmental protection measures are in place to provide periodic supervision,the comprehensive environmental management is of great significance.
