two new air pollution prevention and control standards will be implemented in Beijing from March 1

March 1, 2017

[China paint information] with the approval of the Beijing municipal government, the Beijing Municipal Environmental Protection Bureau recently removed the glass of the table and issued the integrated emission standard of air pollutants (db11/) and the emission standard of air pollutants for organic chemical manufacturing industry (db11/), The standard will be implemented from March 1st, 2017

it is understood that the emission standard of air pollutants with tolerance values of group A and B in each tolerance group (db11/) issued this time has revised and replaced the integrated emission standard of air pollutants (db11/) and the emission standard of air pollutants for metallurgy, building materials industry and other industrial furnaces (db11/). The implementation of the standard is divided into two periods, the first period from the date of implementation of the standard to December 31, 2017, and the second period from January 1, 2018. By tightening the standard limit, the emission of organized particles within the standard coverage can be reduced by 2/3, and the emission of organized VOCs can be reduced by 37.5%

compared with the original standard, the new standard is applicable to the installation of fixed gas turbines and internal combustion engines, oil storage depots, oil tankers, gas stations, oil refining and petrochemical industry, casting and forging industry, cement industry, waterproof coiled material industry, domestic waste and hazardous waste incineration, crematorium, printing industry, wood furniture manufacturing industry, automobile maintenance industry, automobile manufacturing industry, industrial coating process, And the emission control of air pollutants from other fixed sources other than the catering industry

the new standard involves 51 pollutant projects, 9 pollutant projects without monitoring methods such as nitric acid fog are deleted, and 8 pollutant projects such as styrene are added. The maximum allowable emission concentration limits of 30 air pollutants such as acrylonitrile (i.e. organized emission) were tightened, and the concentration limits of 16 unorganized emission monitoring points around units such as cadmium and its compounds were tightened

the emission standard of pollutants for one-time input into the atmosphere of organic chemical manufacturing industry (db11/) is a newly formulated standard. The implementation of the standard is divided into two periods, the first period from the date of implementation of the standard to June 30, 2017, and the second period from July 1, 2017. The standard is applicable to the air pollutant emission management of existing organic chemical production enterprises, as well as the environmental impact assessment, design, completion acceptance and post completion air pollutant emission management of new, reconstructed and expanded organic chemical construction projects. After the implementation of the standard, through measures such as organized and unorganized emission limits and process control requirements, we will guide the whole production process to control the emission of VOCs and particles, and effectively reduce unorganized emissions
