GB 31572-2015Emission standard of pollutants for synthetic resin industry (English PDF)

Foreword

To implement the laws and regulations such as "Environmental protection law

of the People's Republic of China", "Water pollution prevention and control law

of the People's Republic of China", "Air pollution prevention and control law of

the People's Republic of China", to protect environment and prevent and control

pollution, to promote technological progress and sustainable development in

the synthetic resin industry, this standard is hereby developed.

This standard specifies the emission limits, monitoring, supervision and

management requirements for water pollutants and air pollutants in industrial

enterprises and their production facilities of synthetic resins (except for polyvinyl

chloride resins).

For the synthetic resin industrial enterprise's emission of odorous pollutants and

environmental noises, the corresponding national pollutant discharge

standards apply. For the identification, treatment and disposal of solid wastes,

the corresponding national solid waste pollution control standards apply. The

supporting boiler and heat-transfer oil-furnace follows the "Emission standard

of air pollutants for boilers".

This standard is the first release.

Starting from July 1, 2015 for the new facility, and from July 1, 2017 for the

existing facility, the emission of water pollutant and air pollutant shall be

controlled in accordance with the provisions of this standard, at the same time

it will stop implementing the relevant provisions of the "Integrated wastewater

discharge standard" (GB 8978-1996) and the "Comprehensive emission

standard of air pollutants" (GB 16297-1996). Each region may, in accordance

with the local environmental protection needs as well as the economic &

technical conditions, implement this standard in advance after being approved

by provincial people's government.

This standard provides the basic requirements for the control of emission of

water pollutants and air pollutants in synthetic resin industry. For the items

which are not specified in this standard, the local provincial people's

government may formulate local pollutant discharge standards; for the items

which have been specified in this standard, the local provincial people's

government may formulate local pollutant discharge standards that are stricter

than this standard. Where the requirements of environmental impact

assessment or the discharge permit are stricter than this standard or local

standard, it shall be implemented in accordance with the approved

environmental impact assessment or discharge permit.

This standard was formulated by the Science and Technology Standards

Department of the Ministry of Environmental Protection.

Drafting organizations of this standard. China Petroleum and Chemical

Exploration and Design Association Environmental Protection Design

Committee, China Tianchen Engineering Co., Ltd., Zhonglan Lianhai Design

and Research Institute.

This standard was approved by the Ministry of Environmental Protection on

April 3, 2015.

This standard is implemented from July 1, 2015.

For this standard, the Ministry of Environmental Protection shall be responsible

for its interpretation.

Emission standard of pollutants

for synthetic resin industry

1 Scope

This standard specifies the emission limits, monitoring, supervision and

management requirements for water pollutants and air pollutants from synthetic

resin industrial enterprises and their production facilities (including the

enterprises for synthetic resin processing and waste synthetic resin recycling

and processing as well as their production facilities).

This standard is applicable to the management of emission of water pollutants

and air pollutants in existing synthetic resin industrial enterprises or production

facilities, as well as the environmental impact assessment of synthetic resin

industrial construction projects, the design of environmental protection facilities,

the completion environmental protection acceptance, and the management of

emission of water pollutant and air pollutant after it is put into operation.

The monomer production equipment in the synthetic resin enterprise

implements the "Emission standards for pollutant of petrochemical industry",

the production equipment of polyvinyl chloride resin (PVC) implements the

"Emission standards for emission of caustic soda and polyvinyl chloride

industry".

This standard applies to the discharge of pollutants permitted by law. For the

selection of location of the newly-established pollution sources and the

management of the existing pollution source within the specially protected

regions, it shall follow the relevant provisions of such laws, regulations and rules

as the Water pollution prevention and control law of the People's Republic of

China, the Air pollution prevention and control law of the People's Republic of

China, the Marine environmental protection law of the People's Republic of

China, the Law of the People's Republic of China on environmental pollution by

solid wastes, the Law of the People's Republic of China on environmental

impact assessment.

3 Terms and definitions

The following terms and definitions apply to this standard.

3.1

Synthetic resin

A kind of artificially synthetic polymer, which is divided into two types of

synthetic resins, thermoplastic and thermosetting, according to the behavior

after being heated. Wherein.

3.2

Synthetic resin industry

An industry which uses the low-molecular compound-monomer as the main

raw material, to produce the synthetic resin through a polymerization

reaction to form macromolecule, or industry which uses the common

synthetic resin as the raw material, to produce new synthetic resin product

through such methods as modification. It also includes the industries which

use the synthetic resin as raw material to produce synthetic resin products

by such methods as extrusion, injection, pressing, calendering, foaming, etc.,

using the processes of mixing, blending, modification, etc., or the industries

which use the waste synthetic resin as raw material, to produce new

synthetic resin or new synthetic resin products through the methods of

regeneration.

3.3

Effluent volume
