Foreword
To implement the Environmental Protection Law of the People's Republic of
China, the Law of the People's Republic of China on Prevention and Control of
Water Pollution, the Law of the People's Republic of China on Prevention and
Control of Atmospheric Pollution, the Law of the People's Republic of China on
Marine Environmental Protection, and the State Council on Strengthening the
Environment Laws and Regulations on Protection and other "Opinions of the
State Council on the Preparation of National Main Functional Area Planning",
to protect the environment, to prevent pollution, to promote the progress of lead
and zinc industrial production processes and pollution control technologies, this
Standard was formulated.
This Standard specifies the emission limits, monitoring and monitoring
requirements for water pollutants and atmospheric pollutants in the production
process of lead and zinc industrial enterprises. It is applicable to water pollution
and air pollution prevention and management in lead and zinc industrial
enterprises. In order to promote the coordinated development of regional
economy and environment, promote the adjustment of economic structure and
the transformation of economic growth mode, and guide the development
direction of lead and zinc industrial production processes and pollution control
technologies, this Standard specifies particular emission limits for water
pollutants.
The pollutant discharge concentration in this Standard is the mass
concentration.
Lead and zinc industrial enterprises emit odorous pollutants and environmental
noises. The identification, treatment and disposal of solid wastes are applicable
to national solid waste pollution control standards.
This Standard shall be issued for the first time.
From the date of implementation of this Standard, the discharge of water and
atmospheric pollutants from lead and zinc industrial enterprises shall comply
with this Standard. It shall not comply with relevant provisions in "Integrated
Wastewater Discharge Standard" (GB 8978-1996), "Comprehensive emission
standard of atmospheric pollutants" (GB 16297-1996) and "Standard of smoke
and dust emission for industrial kiln and furnace" (GB 9078-1996).
Local provincial people's governments may formulate local pollutant discharge
standards for pollutants not specified in this Standard. For pollutants that have
been stipulated in this Standard, local pollutant discharge standards that are
stricter than this Standard may be formulated.
Emission standard of pollutants
for lead and zinc industry
1 Scope

This Standard is applicable to the management of water pollutants and
atmospheric pollutants in lead and zinc industrial enterprises, as well as
environmental impact assessment, environmental protection facilities design,
and environmental protection acceptance of lead and zinc industrial enterprises
construction projects as well as the management of water pollutants and
atmospheric pollutants after they are put into production.
This Standard does not apply to industries such as calendering of recycled lead,
recycled zinc and lead timber, zinc timber. It is not applicable to non-
characteristic production processes and devices affiliated with lead and zinc
industrial enterprises.
This Standard applies to the discharge of pollutants permitted by law. For site
selection of newly established pollution sources and management of existing
pollution sources in special protection areas, in addition to this Standard, it shall
also comply with the relevant provisions of laws, regulations and rules such as
the Law of the People's Republic of China on Prevention and Control of
Atmospheric Pollution, the Law of the People's Republic of China on Prevention
and Control of Water Pollution, the Law of the People's Republic of China on
Marine Environmental Protection, the Law of the People's Republic of China on
the Prevention and Control of Environmental Pollution of Solid Wastes, the
Environmental Impact Assessment Law of the People's Republic of China.
The water pollutant emission control requirements specified in this Standard
are applicable to the behavior of enterprises directly or indirectly discharging
water pollutants outside their legal boundaries.

4.1 Control requirements for water pollutant emission
4.1.1 From January 1, 2011 to December 31, 2011, existing facility shall
implement the water pollutant emission limits specified in Table 1.
as the basis for determining whether the emission meets the standard
requirements. The product production and effluent volume statistics period is
one working day.
In the case of producing two or more products at the same time in the
production facilities of the enterprise, when it is applicable to different emission
control requirements or national pollutant emission standards of different
industries, and the sewage generated by the production facilities is mixed and
discharged, the most stringent concentration limits specified in the emission
standards shall be implemented. And the benchmark effluent volume emission
concentration of water pollutant shall be converted according to formula (1).
where,
ρbenchmark - the benchmark effluent volume emission concentration of water
pollutant, mg/L;
Qtotal - the total drainage, m3;
Yi - the yield of the ith kind of product, t;
Qi benchmark - the benchmark effluent volume per unit product of the ith kind of
product, m3/t;
ρmeasured - the measured concentration of water pollutant, mg/L.
If the ratio of Qtotal to ΣYi·Qi benchmark is less than 1, then use the measured
concentration of water pollutant as the basis for determining whether the
emission meets the standard requirements.
4.2 Control requirements for atmospheric pollutant emission

acceptance of existing facility production and construction projects, the
environmental protection department in charge of supervision shall monitor the
environmental quality of sensitive areas around the residential, teaching,
medical and other uses. The specific monitoring scope of the construction
project is the surrounding sensitive area determined by the environmental
impact assessment. For existing facility that has not conducted environmental
impact assessment, the scope of monitoring shall be determined by the
competent environmental protection department in charge of supervision,
according to the characteristics and laws of the facility’s sewage discharge and
local natural and meteorological conditions, etc., with reference to the relevant

Do not intentionally dilute emissions. Before the country does not stipulate the
benchmark exhaust volume of other production facilities, the actual measured
concentration shall be used as the basis for determining whether it meets the
standard.
