Ministry of Environmental Protection: The emission reductions of the five major power groups dropped by 45% in the “Eleventh Five-Year Planâ€
The Ministry of Environmental Protection announced on August 29th the assessment results of the total emission reductions of major pollutants in the “Eleventh Five-Year Plan†period, among which the total sulfur dioxide emission reductions of the five major power groups decreased by 44.76% compared with 2005, exceeding the requirements of the target liability book. The "Eleventh Five-Year Plan" dropped by 38.10%, and the desulfurization capacity of the Big Five reached about 90%.
According to the Ministry of Environmental Protection spokesman Tao Detian, 31 provinces, autonomous regions, municipalities directly under the Central Government and the Xinjiang Production and Construction Corps and the State Grid Corporation of China and Huaneng, Datang, Huadian, Guodian and China Power Investment Corporation have all successfully completed the “Ten The total control task issued by the National Plan for the Control of Total Discharge of Major Pollutants during the First Five-Year Plan Period.
Among them, Huaneng, Datang, Huadian, Guodian and China Power Investment Corporation’s five major power groups decreased by 37.17%, 45.05%, 49.72%, 46.19%, and 44.33% respectively compared with 2005, which is compared to the “Eleventh Five-Year Plan†required by the Ministry of Environmental Protection's target responsibility statement. The reduction ratios of 27.60%, 36.90%, 44.90%, 42.80%, and 35.00% all showed more improvement.
The reporter roughly calculated that the proportion of the desulfurization installed capacity of the five largest electric thermal power installations was around 90%. Among them, the highest proportion was Datang, which was 99.3%, and Huadian was the lowest, accounting for 89%. Of the other three companies, CPI was 97.8%, Guodian was 94.6%, and Huaneng was 93.3%.
"At the end of the 11th Five-Year Plan period, a total of 532 million kilowatts of desulphurization facilities for coal-fired power plants were built nationwide. The proportion of assembled capacity of thermal desulphurization machines increased from 12% in 2005 to 82.6%. The proportion of installed thermal power generators in the power industry that accounted for over 300,000 kilowatts accounted for the proportion of thermal power installed capacity. From 47% in 2005 to more than 70%.†Tao Detian said.
In addition, according to statistics from the Ministry of Environmental Protection, the Ministry of Environmental Protection statistics show that as of the end of 2010, a total of 768.25 million kilowatts of small thermal power units were shut down, completing the task of closing 50 million kilowatts in one year and a half in advance. At the same time, steel, cement, coking and papermaking, and alcohol High-energy-consuming and high-emission industries such as MSG, citric acid, and the elimination of outdated production capacity also completed their mission objectives.
In terms of total amount, the assessment results showed that last year, the country’s total discharge of chemical oxygen demand was 12.381 million tons, which was 3.09% lower than in 2009, and the total amount of sulfur dioxide emissions was 21.851 million tons, which was 1.32% lower than in 2009. Compared with 2005, the total COD and SO2 emissions dropped by 12.45% and 14.29%, respectively. In other words, the two mandatory constraints of the chemical oxygen demand and sulfur dioxide are more than 10% of the eleven five emission reduction targets.
Previously, the Ministry of Environmental Protection determined that two mandatory binding indicators, ammonia nitrogen and nitrogen oxides, will be added on the basis of the above two items this year, and it will be determined that the 12th five-year period will be reduced by 8%, 8%, 10% and 10% respectively. Emission reduction targets. Among them, the emission reduction task for 2011 was that the emissions of the four major pollutants mentioned above all decreased by 1.5% compared with 2010.
However, in early July, Vice Minister of Environmental Protection Liejun Zhang revealed at the video conference on total emission reduction audits in the first half of 2011 that COD and SO2 were found through the preliminary dispatch of major pollutants from January to April. Emissions have decreased year-on-year, while the two new pollutant reductions of ammonia nitrogen and nitrogen oxide have not been optimistic.
However, for reasons that are not optimistic, Zhang Lijun said that the main reason is that the energy consumption has led to an excessive increase in nitrogen oxide emissions from process production. Denitrification projects such as coal-fired power plants and cement plants have not been carried out on a large scale, and the scale of outdated production capacity has been eliminated. Strength weakened and so on.
“Currently, some localities rely on ideas, and some localities pursue economic growth one-sidedly, blindly consuming high energy-consuming projects. In the first quarter of this year, the growth rate of high-energy-consuming industries was on an upward trend. If this trend continues, it will not only affect pollution. The realization of emission reduction targets will also seriously affect the structural adjustment and the transformation of development methods." Zhang Lijun said.
