Hash pH meter plays an important role in sewage treatment, mainly reflected in the following aspects:
1. Real time monitoring of water quality acidity and alkalinity
Core function: The pH meter senses the concentration of hydrogen ions in water through electrodes, quickly and accurately measuring the pH value of sewage and reflecting the acidity or alkalinity of the water body.
重要性：
Biochemical treatment optimization: Microorganisms in wastewater (such as aerobic and anaerobic bacteria in activated sludge) are sensitive to pH, and the optimal pH range is 6.5-8.5. PH deviation can lead to a decrease in microbial activity and affect the efficiency of organic matter decomposition.
Chemical treatment control: Neutralization reactions, coagulation precipitation and other processes require precise adjustment of pH value, such as adding lime or sulfuric acid to adjust the acidity and alkalinity, to avoid equipment corrosion or secondary pollution.
2. Hash PH meter ensures stable operation of processing technology
Process monitoring:
Pre treatment stage: Adjust the pH of the primary sedimentation tank or regulating tank to prevent corrosion of the pipeline by acidic or alkaline wastewater.
Biochemical stage: Continuously monitor pH in the aeration tank or anaerobic tank to ensure the effectiveness of microbial treatment.
Deep processing: In the disinfection or denitrification and phosphorus removal process, pH directly affects the chlorine disinfection effect or phosphate precipitation efficiency.
Abnormal warning: When the pH value exceeds the set range, the system can trigger an alarm or link the dosing equipment to adjust the process parameters in a timely manner.
3. Improve processing efficiency and reduce costs
Precise dosing: Through online pH monitoring, the dosage of acid-base agents can be dynamically adjusted to avoid excessive dosing leading to waste or increased costs. For example, precise control of lime dosage can reduce sludge production when neutralizing acidic wastewater.
Energy saving optimization: In the nitrification denitrification process, pH meter data can help optimize aeration and carbon source addition, reducing energy consumption.
4. Comply with environmental regulations
Emission standards: The effluent from sewage treatment plants must meet the "Pollutant Discharge Standards for Urban Sewage Treatment Plants" (GB 18918-2002), and the pH value is usually required to be controlled within the range of 6-9. Real time monitoring of pH meter ensures compliance of discharge water quality.
Data recording: The pH meter can store historical data and generate trend charts for easy inspection by environmental protection departments or process analysis.
5. Hash PH meter adapts to complex working conditions and reliability
Anti interference ability: pH meter adopts high-temperature and corrosion resistant electrode (such as glass gel electrode or antimony electrode), which is suitable for the environment of suspended solids, grease or corrosive substances in sewage.
Automatic cleaning: Some models are equipped with ultrasonic cleaning or brushing functions to reduce the impact of sludge adhesion on measurement.
Multi scenario applications:
Industrial wastewater: Monitor the neutralization process of strong acid/strong alkaline wastewater when treating chemical, electroplating, and printing and dyeing wastewater.
Municipal sewage: Optimize the pH environment of the activated sludge system to improve COD and ammonia nitrogen removal rates.
Rural sewage: Implementing automated control in small-scale integrated equipment to reduce operational difficulties.
