(一)china's "second five" environmental situation

"twelve five" period, china is still in the middle and late industrialization, heavy and chemical characteristics will become more apparent, urbanization and industrialization, promote interaction.

1. pollution abatement of pressures continue to increase. total economy remained high growth, but also to increase the consumption of energy resources, environmental capacity limited basic conditions will not change, pollution reduction targets at increasing the potential reduction in the digestive increment while continuing to reduce inventories, the task very difficult.

2. the pressure continued to increase environmental quality improvement. general environmental factors worsen momentum has been suppressed, heavy metals, persistent organic pollutants, soil pollution, hazardous waste and chemical pollution problems have become increasingly prominent in water, air and soil quality of the overall improvement of the environment is very complex task.

3. to prevent environmental risks pressures continue to increase. environmental violations have occurred, environmental emergencies was high momentum, natural disasters, environmental problems caused by the secondary can not be ignored, nuclear safety, radiation safety and environmental safety, increasing pressure, increasing uncertainties protect environmental safety.

4. address global environmental issues continue to increase the pressure. global environmental problems such as climate change and biodiversity, has become the focus of national interests of the game.

(二)"twelve five" major reduction targets

1. the major water pollutant emissions cuts continue, the total national emissions of chemical oxygen demand by 8% compared with 2010, the total ammonia emissions by 10% compared to 2010.

2. the total amount of major air pollutants continued reduction of the total national emissions of sulfur dioxide in 2010 than 8% of the national total nitrogen oxide emissions by 10 percent from 2010.

3. the unit of gdp energy consumption reduced by 1.6%, carbon dioxide emissions per unit of gdp by 17% reduction.

4.non-fossil fuels in primary energy consumption reached 11.4%

5. 30% reduction in water use per unit of industrial added value.

(三)areas and aspects of the urgent need for industry support

sludge treatment, soil pollution remediation, comprehensive prevention and control of heavy metal pollution, vehicle integrated control of nitrogen oxides, industrial furnace pit off (down) sulfur (nox) and ammonia control, pollution control technology in rural areas, decentralized sewage treatment, dust bag and voc control, resource utilization, including the total mineral resources, waste electrical and electronic products, auto parts, kitchen waste, forestry waste and environmental services.

(四)environmental protection industry development priorities

1. sewage treatment, new sewage treatment facilities. proposed construction of sewage treatment capacity 50 million tons / day of "twelve five" period; sewage treatment plant supporting pipe network construction. improve sewage treatment increased the load factor is about 25,000 km pipeline network, the existing sewage treatment plant pipe network improvement need to increase the 60,000 kilometers, the new sewage treatment plant to be supporting 75,000 km pipeline network. sewage treatment plant upgrade. "twelve five" period, all cities and counties in key watersheds sewage treatment plant required to achieve a b standard, focusing on watershed capital cities and key cities of the sewage treatment plant required to achieve an a standard, into the enclosed waters and across the seas water quality has a direct impact on the regional sewage treatment plant should be used with enhanced nitrogen and phosphorus removal function processes. wastewater reuse. focus on the implementation of dryland water recycling work. decentralized wastewater treatment facilities. encourage more than 1,000 towns in accordance with a b emission standards, building decentralized wastewater treatment facilities.

2. sludge treatment, 2015 national urban sewage treatment capacity will reach 150 million tons / day, producing about 120,000 tons of sludge / day. sludge treatment: incineration, land use, composting, landfill.

3. industrial pollution prevention and control, is expected to improve emission standards and industrial enterprises through restructuring, improving stability through regulatory compliance emission levels, reduction of cod and ammonia emissions.

4. non-point source pollution control, including comprehensive treatment of rural, livestock and agricultural nonpoint source pollution control pollution control.

5.desulfurization and denitrification, the power industry fgd. desulfurization power industry market is not standardized, but customs facilities still need to be standardized policies. the new "five-second" period of about one hundred million kilowatts 1.8-2.3 units (including replacing part of the elimination of small thermal power) will be fully desulfurization. power industry flue gas denitrification. still in its infancy, the operation is not good, the catalyst to be imported, technology, equipment localization rate is low. steel industry sintering flue gas desulfurization. "twelve five" should increase the sintering flue gas desulfurization efforts on the new sinter (pellet) facilities must synchronize the construction of flue gas desulfurization equipment; existing enterprises, the use of high-sulfur raw material sintering machine, located two control zones and major cities 90 square feet or more sintering machine should deadline to install flue gas desulphurization facilities. industrial boilers and cement industry denitration demonstration. "twelve five" period, the cement industry to carry out the nsp sncr demonstration project. other industries desulfurization. "twelve five" period, sulfur dioxide emissions for industrial boilers, and other non-ferrous metal smelting industry control.

6. dust bag, "twelve five" period, dusting the power industry to launch a new round of technological innovation, and dust removal equipment from classic to bag dust or change the direction of electric bag composite dust, emissions control in less than 30mg / nm3 (except coal gangue as the main fuel). to this end, the new unit to promote the use of efficient dust collector; iron and steel, nonferrous metal industry demand for large dust bag.p>

7. municipal waste, solid waste disposal capacity, "twelve five" period is expected to reach 350,000 tons / day, harmless treatment rate of not less than 80%, key environmental protection cities harmless disposal rate should reach 85% or more; achieving more than 90 percent of the county built a life garbage treatment facilities; complete existing msw landfill leachate treatment facilities complete the task of transformation; increases in densely populated waste incineration rate should not be less than 50%, in waste incineration in the western region of not less than 25%. while speeding up the municipal solid waste incineration fly ash utilization, new technologies and demonstration projects.

8. hazardous waste and medical waste disposal, "second five" hazardous waste and medical waste continue to carry out the main task for hazardous waste and medical waste disposal facilities, hazardous waste disposal capacity is expected to reach 4.17 million tons / year, medical waste centralized processing capacity should reach 2072 tons / day.

9. contaminated soil remediation, contaminated soil remediation including legacy site soil contamination caused by pollution control and remediation, soil pollution control and remediation of ecologically sensitive areas, soil pollution hotspots such as governance and repair.

10. environmental monitoring and emergency response capacity, cities and counties tianpingbuqi provincial environmental monitoring equipment, focusing on provincial and municipal levels to enhance environmental monitoring capacity. meet routine environmental monitoring capabilities, turning gradually strengthen detection, pm2.5, pops, greenhouse gases, voc and other aspects of detection capabilities, strengthen the whole source water quality analysis capabilities, the establishment of early warning detection system of border rivers, establish and improve the rural environmental regulation system.

11. the environmental services, to develop pollution control facilities, professional and social service operations. development of environmental consulting industry, focusing on the development of environmental supervision, environmental risk damage assessment, environmental technology assessment, environmental insurance, environmental audits, cleaner production audits, environmental management certification, environmental education, training and other emerging popularity of environmental consulting services. gradually advancing environmental monitoring service. encourage the development of integrated environmental services system solutions, and actively explore environmental services contract for environmental services and other new models. environmental services union and encourage regional industrial clusters, and encouraging alliances between enterprises in the form of an integrated overall service environment.
