Introduction
Analysis of the core content of the standard
| Technical elements | Chlorination treatment | Acidification treatment |
|---|---|---|
| Main function | Inhibit microbial reproduction | Prevent chemical precipitation |
| Necessity determination | Total bacteria count/water source type | pH value/total dissolved solids |
| Typical concentration | 1-20 mg/L | pH 6.0-7.0 |
Key points of technical implementation
1. Treatment mode selection
The standard specifies three injection modes:
- Continuous injection: Applicable to systems with high risk of blockage
- Periodic injection: Recommended for medium and low risk systems
- Enhanced injection: Seasonal treatment in case of severe blockage
2. Key parameter control
Actual cases show that when using pressure-compensated injectors, the enhanced injection mode may lead to:
- The risk of diaphragm corrosion increases by 30%
- Flow deviation exceeds the standard limit
Standard Evolution Analysis
Compared with the old version of the standard, the main progress of T/JSGS 001-2021 is:
| Technical Dimensions | Improvements in the New Version |
|---|---|
| Safety Protection | Added 8 specific operating specifications |
| Parameter Calculation | Provide standardized calculation formulas |
Implementation Suggestions
Operation Process Optimization
The following steps are recommended:
- Pretreatment Water Quality Testing (pH/Residual Chlorine)
- Select a mode according to Importer Type
- Establish a treatment effect feedback mechanism
Risk Prevention and Control
Special Attention:
- When chlorine treatment is used, acid must be added if pH > 7
- Avoid adding chlorine to crops during the seedling stage
- Flush the system before and after treatment
