Introduction
1. Background and significance of standard formulation
Grille filter is an indispensable equipment in urban water supply and drainage and industrial water treatment projects, mainly used to intercept and remove floating and suspended debris in the water. The formulation of GB/T 37565-2019 "General Technical Conditions for Grille Filters for Water Supply and Drainage" fills the gap in standardization in this field and provides a unified basis for product quality and technical requirements.
2. Comparison of standard frameworks
| Standard dimensions | GB/T 37565—2019 | International similar standards | Industry standard comparison |
|---|---|---|---|
| Classification and model | 9 types, clear model compilation rules | Partial corresponding standards of ISO/IEC 16042 | Based on CJ/T 251-2016 |
| Performance parameters | Covering key indicators such as width, clearance, installation angle, etc. | Consistent with EN 12056 | Supplement the requirements for high-chain and mobile equipment |
| Material requirements | Specify the material standards for stainless steel, carbon steel, etc. | Comply with ISO 1368-2 specification | Add anti-corrosion treatment requirements |
3. Implementation Suggestions
Case Analysis: Application of Stepped Screen Sludge Remover
A city sewage treatment plant uses a stepped screen sewage remover (model CWJ-JT-2000-20-1.5), which effectively intercepts floating objects in the influent during operation, and the screen residue collection efficiency reaches 98%. Suggestions:
- Select the appropriate model according to the amount of water to be treated and the type of impurities
- Regularly check the self-cleaning function of the tooth rake to avoid blockage
- Strictly carry out anti-corrosion treatment in accordance with the standard requirements to extend the life of the equipment
4. Conclusion
The implementation of GB/T 37565-2019 will significantly improve the application level of screen decontamination machines in water supply and drainage projects. It is recommended that relevant companies strictly carry out production and inspection in accordance with the standard requirements, and pay attention to subsequent technical updates.
