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.

been stipulated in this Standard, local pollutant discharge standards that are
stricter than this Standard may be formulated.

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.

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.

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, 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
