Introduction
In-depth interpretation of the National Standard of the People's Republic of China GB/T 35183—2017
Background and significance of the formulation of the standard
Vertical Shaft Surface Aerator is an important oxygenation equipment in the sewage treatment system, mainly used to increase the dissolved oxygen content of the water body and promote the biodegradation process. The formulation of GB/T 35183—2017 aims to standardize the technical requirements, test methods and inspection rules of the surface aerator to ensure that the product quality and performance meet the needs of the environmental protection industry.
Technology Evolution Analysis
With the rapid development of the environmental protection industry, the surface aerator has gradually developed from the early simple structure to the direction of high efficiency and intelligence. This standard combines advanced domestic and foreign technological achievements and systematically stipulates the classification, model naming, basic parameters and other aspects of the equipment.
| Technical requirements | Specific indicators | Scope of application |
|---|---|---|
| Performance stability of the whole machine | Load current fluctuation range ≤±5%, vibration intensity ≤4.5mm/s | Under all operating conditions |
| Power efficiency | Inverted umbrella type ≥2.20kg/(kW·h), pump type ≥1.90kg/(kW·h) | Measured under standard conditions (water temperature 20±2°C, atmospheric pressure 101.325kPa) |
| Life of the whole machine | MTTF≥8000h, life ≥10 years | Wastewater treatment plants, environmental protection projects and other fields |
Standard framework comparison and application analysis
Actual application case: Equipment selection of a certain urban sewage treatment plant
When selecting a surface aerator, a certain urban sewage treatment plant compared technical parameters according to GB/T 35183-2017 standard. They chose a vertical inverted umbrella type (BLS) surface aerator, model BLS325NB/110, with a motor power of 110kW, a nominal impeller diameter of φ325mm, and a power efficiency of 2.3kg/(kW·h). The equipment runs stably, and the vibration intensity is controlled within 4.2mm/s, meeting the standard requirements.
Implementation Recommendations
Selection Guide
- Choose the appropriate model according to the water volume and water quality requirements.
- Consider the long-term operating environment of the equipment (such as temperature, humidity, etc.).
- Preferably use a surface aerator with variable frequency speed regulation function to adapt to load changes.
Maintenance and Care
- Regularly check the impeller balance and immersion depth to ensure maximum power efficiency.
- Monitor the lubrication status of the reduction box and replace the lubricating oil in time.
- Perform a comprehensive vibration test once a year to ensure safe operation of the equipment.
