"Thirteen Five-Year" period, the water is more clear blue goal how to achieve? Yesterday, the Nanjing Environmental Protection Department issued the "Nanjing" 13 "five" environmental protection plan "draft (hereinafter referred to as planning), scheduled for the next five years environmental management list: ten binding targets for environmental governance delineation. From the sky to the ground, water quality, "temperament", soil quality, quality must be substantially improved; people are most concerned about "blue sky index" that urban air quality standards to achieve the proportion of the number of days, from the "second five" %, To 72% in 2020, the city heavily polluted weather and strive to reduce the 20%; clear industrial pollution before the land can not be used for residential rehabilitation and highly related to human health development.

       Status: air quality to more than the standard number of days that is commonly known as the blue sky, is the most popular indicators of environmental quality assessment. Yesterday's draft plan shows that the haze weather days accounted for a larger proportion, PM2.5 excessive serious, heavily polluted weather has occurred. In 2015, Nanjing PM2.5 annual average concentration of 57 micrograms / cubic meter, down 26.9% compared to 2013, Jiangsu Province, the first drop; air quality standards to reach the secondary level of 64.4%, compared to 55.3% in 2013, An increase of 9.1 percentage points.

       The future: Nanjing, "Thirteen Five" environmental protection, the main indicators mentioned in the year 2020, PM2.5 annual average concentration to be reduced to 45.6 micrograms per cubic meter. Urban air quality standards to reach the level of the number of days the proportion increased to 72%. Nanjing will strengthen the emergency warning and regional joint control joint control, by 2020, the city heavily polluted days strive to reduce 20%.

       Intensified measures: strict control of volatile organic compounds. To carry out the construction of monitoring and monitoring system of volatile organic compounds in key parks, to promote the investigation and comprehensive treatment of volatile organic compounds in key industries such as petrochemicals, organic chemicals, surface coating, packaging and printing, wood-based panel manufacturing, etc., and comprehensively promote the technology of "leakage detection and repair" Chemical parks (concentrated areas) and key enterprises of volatile organic compounds emission source remediation work. By 2020, the emission of VOCs in key industries will be reduced by more than 10%. The utilization rate of environment-friendly coatings such as water-based, high-solid and UV coatings for furniture manufacturing, engineering machinery manufacturing, electronic equipment manufacturing and automobile manufacturing will reach 50% the above.
