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.

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,

rhobenchmark - 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;

rhomeasured - the measured concentration of water pollutant, mg/L.

If the ratio of Qtotal to sumYi·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

4.2.1 From January 1, 2011 to December 31, 2011, existing facility shall

implement the atmospheric pollutant emission limits specified in Table 4.

4.2.5 In the production process after the completion of environmental protection

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

environmental impact assessment technical guidelines. The local government

shall be responsible for the environmental quality of its jurisdiction and take

measures to ensure that the environmental conditions meet the requirements

of environmental quality standards.

4.2.6 The production processes and devices that produce atmospheric

pollutants must establish local or integral gas collection systems and

centralized purification treatment devices. All stack height shall be no less than

15 m. When there are buildings within a radius of 200 m around the stack, the

stack height shall be higher than the maximum height by more than 3 m.

4.2.7 The lead and zinc smelting furnaces have an excess air ratio of 1.7. The

measured pollutant emission concentration of lead and zinc smelting furnaces

shall be converted into the benchmark excess air coefficient emission

concentration. Production facilities shall adopt reasonable ventilation measures.

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.
