Introduction
Interpretation of the National Standard of the People's Republic of China GB/T 19570—2017
This standard is a technical specification for sewage discharge pipeline engineering, aiming to guide the scientific design and construction of sewage discharge systems and ensure the protection of the marine environment.
1. Background and significance of standard revision
In recent years, with the rapid development of my country's coastal economy and the improvement of people's living standards, the requirements for environmental protection have been increasing. The original standard GB/T 19570-2004 can no longer fully meet the needs of the new situation, mainly reflected in:
- The term "surge well" has been added
- The comparison requirements for sewage outlets and mixing areas have been clarified
- The quality supervision requirements during the construction phase have been strengthened
2. Overview of the main contents of the standard
This standard covers several key links of sewage sea discharge pipeline projects, including:
| Chapters | Main contents |
|---|---|
| Route survey and selection (5 chapters) | Including technical requirements such as marine environmental investigation, meteorological and hydrological observation, and seabed topography mapping. |
| Discharge pipe and diffuser design (6 chapters) | Involves pipeline material selection, structural design, anti-corrosion measures and construction technology. |
| Management of sewage discharge to the sea mixing zone (7 chapters) | Includes water quality monitoring, pollution plume prediction, re-dilution calculation, etc. |
3. Recommendations for standard implementation
To ensure the scientificity and effectiveness of sewage discharge to the sea pipeline project, it is recommended that:
- Strengthen the preliminary investigation of the route area and avoid ecologically sensitive areas.
- Use high-quality materials and advanced technology, such as steel pipes and fiberglass pipes.
- Establish a full-process monitoring system to ensure that the discharged water quality meets the standards.
- Formulate emergency plans to deal with sudden environmental events.
