At the video conference on the verification and accounting of total emissions reductions in the first half of 2011 held in June 30th in China, Zhang Lijun said that in 2011, the task of emission reduction determined by the state was that the emissions of the four major pollutants were equal to those of 2010. Decline 1.5%. Considering the investment impulses in the beginning of the “Twelfth Five-Year Planâ€, the increasing recovery of the international economy, and the countermeasures that need time to deploy new binding indicators, the emission reduction task is quite arduous.
The Ministry of Environmental Protection recently conducted a preliminary survey on the reduction of major pollutants in the country from January to April, and found that COD and CO2 emissions have decreased year-on-year, while ammonia nitrogen and nitrogen oxide emissions have increased. The situation is not optimistic.
According to the analysis of the Ministry of Environmental Protection, the two newly added pollutants of ammonia nitrogen and nitrogen oxide increased, mainly due to the reduction in scale and intensity of elimination of backward production capacity, and the excessive increase in nitrogen oxides emitted from the process production due to energy consumption, coal-fired power plants. Denitrification projects such as cement plants have not been carried out on a large scale.
The analysis shows that from the calculation of chemical oxygen demand and ammonia nitrogen addition, the parameters such as GDP, industrial added value, and national urban population growth rate that determine the emissions are all significantly higher than those in the same period of last year, adding new emission pressures. Larger; From the calculation of the new amounts of dioxide* and nitrogen oxides, the output of motor, steel, non-ferrous metals, building materials, cement and other industries have shown a rapid growth trend, especially the large amount of thermal power generation. The increase has led to an excessive increase in the emissions of two air pollutants.
The reporter learned that the Ministry of Environmental Protection has requested full-caliber verification and accounting of key industries, in particular detailed investigations of the reduction of nitrogen oxides emitted by power plants.
