Integrated wastewater discharge standard
1 Application scope
This standard specifies the terms and definitions of wastewater discharge, corresponding standard grading, requirements for pollutant discharge control, requirements for pollutant monitoring, implementation and supervision, etc.
This standard is applicable to the discharge management of water pollutants from existing pollutant discharge units in Tianjin, as well as the environmental impact assessment of construction projects, the design of environmental protection facilities of construction projects, the completion acceptance and the discharge management after putting into service.
This standard is applicable to pollutant discharge behaviors allowed by law. The site selection of the pollution source set newly and the management of the current pollution source in the special protected zone shall be executed in accordance with the relevant provisions of laws, regulations and rules such as 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 and Law of the People's Republic of China on Environmental Impact Assessment.
Since the comprehensive discharge standard and the professional discharge standard are not implemented alternately, where there is a national or provincial professional water pollutant discharge standard, the corresponding professional water pollutant discharge standard shall be implemented according to its application scope, while the water pollutant discharge from other pollutant discharge units shall comply with this standard.
The discharge control requirements of water pollutants specified in this standard are applicable to the behaviors of the discharge units discharging water pollutants, directly or indirectly, out of their legal boundaries.
