Introduction
Interpretation of GB/T 43359-2023 National Standard of the People's Republic of China
1. Background and significance of standard formulation
With the rapid development of my country's printing and dyeing industry, the amount of wastewater discharged and the concentration of pollutants have increased year by year, causing great pressure on the water environment. GB/T 43359-2023 "Integrated Equipment for Membrane Process for Printing and Dyeing Wastewater" came into being, aiming to standardize the application of membrane technology in the treatment of printing and dyeing wastewater and improve the efficiency and quality of reclaimed water reuse and brine reuse.
2. Comparison of standard frameworks
| Standard dimensions | GB/T 43359—2023 | Comparative analysis |
|---|---|---|
| Scope of application | Applicable to membrane-based integrated equipment for reuse of reclaimed water and brine after physical, chemical and biochemical treatment of printing and dyeing wastewater. | Focus on specific areas with clear technical requirements. |
| Core technologies | Ultrafiltration, nanofiltration, reverse osmosis, electrodialysis, etc. | Combined application of multiple membrane separation technologies. |
| Water quality indicators | COD, chromaticity, turbidity and other indicators of recycled water and recycled brine are clearly specified. | Pay attention to the quality of treated water. |
3. Core technologies and equipment
The integrated equipment consists of ultrafiltration, nanofiltration, reverse osmosis, electrodialysis and other equipment, including:
- Submerged ultrafiltration unit: used for preliminary filtration treatment.
- Nanofiltration or reverse osmosis unit: to achieve deep separation and reuse.
- Pressure ultrafiltration unit: to further improve water recovery rate.
- Electrodialysis unit: used for brine classification and reuse.
4. Detailed explanation of technical requirements
The technical requirements of integrated equipment cover aspects such as processing capacity, recovery rate, and water quality indicators:
- Processing capacity: The processing capacity of integrated equipment should reach the rated processing capacity, and the equipment water volume balance of only the reclaimed water reuse system is shown in Appendix A.1.
- Recovery rate: The reclaimed water recovery rate shall not be less than 50%, and the brine recovery rate shall not be less than 50% (in terms of TDS).
- Water quality indicators: The water quality of reclaimed water and reclaimed brine shall comply with the provisions of Table 1.
5. Implementation suggestions
To ensure the effective implementation of the standard, the following suggestions are put forward:
- Strengthen the standardization of equipment selection, installation and commissioning.
- Focus on the design and maintenance of electrical control systems.
- Strengthen the implementation of anti-corrosion and safety measures.
