China drying wire mesh News Department of Environmental Protection spokesman Tao Detian today informed the media, the Ministry of Environmental Protection recently completed the verification of emission reduction accounting of the total amount of major pollutants by 2011 all provinces, autonomous regions and municipalities and eight central enterprises. The results showed that the national chemical oxygen demand, ammonia nitrogen and sulfur dioxide emissions achieved a year-on-year decline, and the nitrogen oxide emissions increased year-on-year.

Tao Detian said: The Twelfth Five-Year Plan for National Economic and Social Development proposes that during the “Twelfth Five-Year Plan” period, the state implements total discharges of four major pollutants including chemical oxygen demand, ammonia nitrogen, sulfur dioxide, and nitrogen oxides. control. 2011 is the first year of the “Twelfth Five-Year Plan”. To fully understand the progress of emission reduction work across the country and accurately verify the reduction of pollutants in the country, the Ministry of Environmental Protection of the provinces, autonomous regions, municipalities and Xinjiang Production and Construction Corps and 8 central enterprises The major pollutant discharges in 2011 were carefully checked and accounted for. The results show that: In 2011, the total discharge of chemical oxygen demand across the country totaled 24,999,000 tons, a decrease of 2.04% from 2010; the total amount of ammonia nitrogen emissions was 2.604 million tons, a decrease of 1.52% compared with 2010; the total amount of sulfur dioxide emissions was 22.179 million tons, compared with 2010. The annual decrease was 2.21%; the total amount of nitrogen oxides emissions was 24.043 million tons, which was 5.74% higher than that in 2010.

According to reports, in 2011, Beijing, Shanghai, Zhejiang Province and Henan Province ranked the top four in the average decline in the discharge of major pollutants. Beijing's chemical oxygen demand, ammonia nitrogen, sulfur dioxide and nitrogen oxide emissions all achieved a year-on-year decrease of 3.53%, 2.98%, 6.22%, and 4.75% respectively; Shanghai's chemical oxygen demand, ammonia nitrogen, sulfur dioxide, and nitrogen oxides emissions The total amount achieved decreased by 6.26%, 3.40%, 5.90%, and 1.66% respectively. However, there are still prominent problems in the pollution reduction work in individual regions. Among them, all four major pollutant discharges in Xinjiang Uygur Autonomous Region increased year-on-year; Heilongjiang ammonia nitrogen, sulfur dioxide, and nitrogen oxides emissions rose by 2.03%, 1.65%, and 4.10% respectively year-on-year.
