火力发电行业是国民经济重要的组成部分,同时也是对生态环境有重要影响的行业。火力发电企业是我国二氧化硫、氮氧化物、烟尘等大气污染物的主要排放源。近年来,在国民经济高速发展的带动下,对电力的需求和对电力行业的投资快速增长。在这种形势下,能否有效地控制新增电力企业的污染物排放,同时解决现有电厂的环保欠账问题,是关系到国家环境保护事业成败的重大课题。污染物排放标准是国家的环境保护技术法规,是贯彻落实环境保护法律的技术依据,也是判定企业排污行为合法与否的基准。制定和实施适合于我国国情的国家火电厂排放标准是解决火力发电环境污染问题的重要手段。新修订的国家污染物排放标准《火电厂大气污染物排球标准》(GB13223—2003)已于2004年实施,新标准按火电厂建设时间划分为3个时间段,分别规定了大气污染物排放限值和开始实施时间。新排放标准的出台和实施,对于我国的经济发展和环境保护都具有重要意义,对我国环境保护产业和污染治理技术市场的发展必将产生重大影响。
Thermal power generation industry is an important part of the national economy, but also have an important impact on the ecological environment of the industry. Thermal power generation enterprises are the main sources of emissions of atmospheric pollutants such as sulfur dioxide, nitrogen oxides and soot in our country. In recent years, driven by the rapid development of the national economy, the demand for electricity and the rapid investment in the power industry have increased rapidly. In this situation, whether it can effectively control the pollutant emissions of newly-added electric power enterprises while solving the environmental problems of current power plants is a major issue that has a bearing on the success or failure of the country’s environmental protection undertakings. Pollutant discharge standards are the country’s environmental protection laws and regulations, is the technical basis for the implementation of environmental protection laws, but also to determine the legal basis for the enterprise sewage behavior. The formulation and implementation of national thermal power plant emission standards that are suitable for China’s national conditions are an important means to solve the environmental pollution problem of thermal power plants. The newly revised national pollutant discharge standard “Thermal Power Plant Air Pollution Volleyball Standard” (GB13223-2003) was implemented in 2004, the new standard by the thermal power plant construction time is divided into three time periods, respectively, the provisions of the air pollutant emission limits Value and start of implementation time. The promulgation and implementation of the new emission standards are of great significance to China’s economic development and environmental protection and will have a significant impact on the development of China’s environmental protection industry and the pollution control technology market.
