1 Application Scope
This standard specifies the emission limit of water and air pollutants for typical processing and device in synthetic leather and artificial leather industrial enterprise.
This standard is applicable to the emission management of water and air pollutants for typical processing and device in existing synthetic leather and artificial leather industrial enterprise.
This standard is applicable to the environmental impact assessment, environment protection facility design, completion acceptance of environmental protection as well as the emission management of water and air pollutants after commissioning for synthetic leather and artificial leather industrial construction project.
This standard only applies to legal pollutants emission; the site selection of new pollution sources and the management of existing pollution source within special protected zone are in accordance with "Law of the People's Republic of China on the Prevention and Control of Atmospheric Pollution", "Law of the People's Republic of China on Prevention and Control of Water Pollution", "Marine Environment Protection Law of the People's Republic of China", "Law of the People's Republic of China on Prevention of Environmental Pollution Caused by Solid Waste", "Law of the People's Republic of China on Prevention and Control of Radioactive Pollution", "Law of the People's Republic of China on Environmental Impact Assessment".
The emission control requirements of water pollutants specified in this standard are applicable to the behavior of the enterprises discharging water pollutants to the environmental water.
In the case of enterprise discharging waste water to the urban drainage system equipped with wastewater treatment plant, the emission control requirements of pollutants is determined through negotiation of the enterprise and urban wastewater treatment plant according to the wastewater treatment capacity or according to the relevant standards, it then shall be submitted to the local environmental protection competent department for record; the urban wastewater treatment plant shall ensure that the emission pollutants reach the related requirements for emission standard.
Where the construction projects are intended to discharge waste water to the urban drainage system equipped with wastewater treatment plant, it shall be implemented by the construction organization and urban wastewater treatment plant according to the above provisions.
