MEP Announces Reduction of Major Pollutants of China in 2011
Article type: Translated

MEP spokesperson Tao Detian announced today that Ministry of Environmental Protection has completed examination of total pollution reduction of all provinces, autonomous regions, municipalities and 8 state-owned enterprises in 2011. The results indicate discharges of COD, NH3 and SO2 nationwide have dropped compared to the same period of 2010 while the discharge of NOx has increased.
Tao said that the 12th Five-Year Program for National Economic and Social Development identified the measure of total pollution control on the four major pollutants, namely COD, NH3, SO2 and NOx. The year 2011 is the first year of the 12th phase. MEP launched examination of pollution discharges of 2011 on all provinces, autonomous regions, municipalities, Xinjiang Production & Construction Corps and 8 state-owned enterprises in order to get a full picture of the progress of pollution reduction and ascertain the total reductions across the country. According to the examination, in 2011, national discharges of COD totaled 24.999 million tons, down 2.04% against that of 2010, discharges of NH3 and SO2 reached 2.604 million tons and 22.179 million tons, declining by 1.52% and 2.21% respectively. The total discharge of NOx grew to 24.043 million tons, a jump of 5.74% compared to that of 2010.
Tao added that in 2011, all departments in different regions have been serious in implementing the arrangement of energy conservation and emission reduction made by the CPC Central Committee and the State Council. They employed legal, economic, technical and administrative tools to strengthen the work, achieving positive progress. Among all the provinces and cities, Beijing, Shanghai, Zhejiang and Henan Province head the list in terms of average reduction of the four pollutants. Specifically, Beijing reduced discharges of COD, NH3, SO2 and NOx by 3.53%, 2.98%, 6.22% and 4.75% respectively compared with that of the previous year and Shanghai also achieved emission reduction of all the above pollutants respectively by 6.26%, 3.40%, 5.90% and 1.66%. However, we should also notice that there are prominent problems with some areas in pollution reduction. For example, discharges of the four pollutants in Xinjiang have all increased compared with that of 2010 and Heilongjiang Province saw growing discharges of NH3, SO2 and NOx by 2.03%, 1.65% and 4.10% respectively.
In terms of major measures for pollution reduction, the country added new capacity for urban sewage treatment by 11 million tons in 2011and utilization of 1.3 million tons of used water per day. The new desulphurization units that have been put into operation had an installed capacity of 68 million kW, which brought the proportion of installed capacity of all desulphurization units to that of thermal units to 87.6% from 82.6 in 2010. The capacity of new denitrification units put into operation totaled 49.52 million kW and the proportion of installed capacity of all denitrification units to all thermal units increased from 11.2% in 2010 to 16.9% in 2011. There were 93 new flue gas desulphurization facilities for sintering machines, covering an area of 15,800 sq. m. Sintering machines with desulphurization facilities covered 32.8% of the total sintering area of iron & steel sector, a big increase compared with 19.3% in 2010. The role of automatic monitoring system built by the end of the 11th Five-Year Plan period was given full play with 95% of the desulphurization facilities putting into operation. Flue gas bypass of 56 desulphurization units with a capacity of 23.7 million kw. was removed, improving the desulphurization efficiency of thermal units to 73.2% from 68.7%. 5171 large scale raising farm and raising communities have improved their facilities for sewage treatment and solid waste disposal. Outdated production capacity was eliminated including 3.46 million kW small thermal units, 7,000 sq. m. sintering machines, 7.1 million tons in papermaking, 2.3 billion meters of printing and dying sector and 42 million tons of cement production. A group of companies or production lines concerning heavy metal pollution were also shut down.
