Safety Precautions During the Operation of Activated Carbon Filters, Focusing on Six Key Dimensions: Equipment Pressure and Fluid Safety, Electrical and Mechanical Safety, Chemical Agent Safety, Personnel Protection, Environmental Compliance, and Emergency Response, to Comprehensively Avoid Equipment Failures, Personnel Injuries, and Environmental Risks. Specific Details Are as Follows:
I. Equipment Pressure and Fluid Safety: Prevent Overpressure, Leakage, and Water Hammer Impact
Strictly Control Pressure Standards
Operating pressure must remain stable within the design range (typically 0.1-0.6 MPa), and overpressure operation is strictly prohibited. Regularly calibrate pressure gauges to ensure accurate data, preventing pressure loss due to instrument failure and potential tank structure damage.
Gradually operate valves when starting or stopping equipment. Before starting the backwash pump and water inlet valve, open the vent valve to expel air, preventing water hammer impact from damaging pipes, valves, and tank welds.
Prevent Leakage and Structural Damage
Inspect flange joints, valve gaskets, and tank welds before operation to ensure bolts are tightened and seals are intact. Immediately shut down and repair any leaks to prevent leakage expansion under pressure.
Prohibit arbitrary welding, drilling, or modifications on the tank body. If adjustments are necessary, contact the manufacturer for professional operation to prevent damage to the equipment's pressure-bearing structure.
Special Weather Protection
Ensure equipment insulation in winter to prevent pipeline and tank icing and cracking. For outdoor equipment, check stability during heavy rain or strong wind conditions and pause operation if necessary.
II. Electrical and Mechanical Safety: Avoid Equipment Operation Fault Risks
Standard Electrical Equipment Operation
Motor equipment such as backwash pumps and fans must be properly grounded. Before operation, check for loose connection terminals and damaged insulation layers to avoid electrical hazards in damp or corrosive environments.
Strictly prohibit operating electrical switches with wet hands. Maintain dry and ventilated conditions around equipment to prevent electric shock incidents. Regularly clean dust and moisture from electrical components to extend their service life.
Mechanical Component Operation Monitoring
Continuously observe the operating status of backwash pumps and fans. Immediately shut down and investigate if abnormal vibration, noise, or current exceeds standards to prevent equipment burnout or component damage.
Monthly check the flexibility of valve operation. Apply water-resistant and anti-aging lubricant to valve cores and stems, and clean impurities inside valves to prevent core wear and water loss control.
III. Chemical Agent Safety: For Chemical Regeneration / Auxiliary Cleaning Scenarios
Agent Storage and Configuration
Acids, alkalis, and disinfectants must be stored in sealed, classified containers away from ignition sources and oxidizers, with clear hazard labels to prevent accidental reactions from leakage or improper storage.
When configuring agents, wear acid-resistant/alkali-resistant protective suits, goggles, and respirators. Operate in well-ventilated areas and strictly follow dilution ratios to avoid agent splashes causing corrosive injuries.
Agent Use and Residual Disposal
Control agent concentration and soaking time during chemical cleaning to prevent prolonged high-concentration agent contact with tank bodies, which may lead to liner corrosion or material aging.
After cleaning, thoroughly rinse the tank with clean water to ensure pH values meet standards before resuming operation, preventing agent contamination of subsequent water or equipment corrosion.
IV. Personnel Protection: Avoid Personal Injuries
Wear Professional Protective Equipment
For routine operations (e.g., inspections, valve adjustments), wear anti-slip gloves and goggles. When handling chemical agents, additionally wear acid-resistant/alkali-resistant protective suits and respirators. For high-altitude work (e.g., inspecting tank vent valves), securely fasten safety harnesses.
Standardize Work Area Management
Set up warning signs around equipment to prohibit无关人员 from staying. Avoid personnel gathering in hazardous areas such as backwash drainage outlets or agent operation zones to prevent injuries from water sprays or agent vapor.
Strictly Follow Shutdown Maintenance Procedures
Before opening covers for maintenance or filter replacement, ensure water inlet and outlet valves are closed, completely shut down, and pressure is released, draining tank water. Only operate after confirming no pressure remains, strictly prohibiting work under pressure.
V. Environmental Compliance: Ensure Wastewater Discharge Standards
Backwash Drainage Treatment
Backwash drainage contains high concentrations of suspended solids, organic matter, and pollutants, requiring treatment to meet standards before discharge. Strictly prohibit direct discharge into municipal pipelines or natural water bodies.
For filters treating industrial wastewater, backwash drainage must be treated separately based on pollutant types (e.g., chemical precipitation for heavy metal-containing wastewater) to prevent environmental pollution.
Solid Waste Disposal
Used activated carbon must be collected as hazardous waste according to regulations and disposed of by qualified units. Strictly prohibit arbitrary disposal to prevent soil or water pollution.
VI. Emergency Response: Rapidly Address Unexpected Situations
Equipment Failure Emergency
In case of tank leakage or pipe rupture, immediately close water inlet and outlet valves, activate bypass systems, and temporarily repair leaks to prevent escalation. If overpressure occurs, promptly open pressure relief valves.
Personnel Injury Emergency
Equip the site with eyewash stations, first-aid kits, and emergency water sources. If skin or eyes contact污水 or chemical agents, immediately rinse with large amounts of water for over 15 minutes and seek medical attention promptly.
Water Quality Abnormality Emergency
If water quality suddenly changes (e.g., pollutant levels exceed standards), immediately switch to bypass systems and investigate water inlet pollution or equipment faults to prevent discharge of non-compliant water causing subsequent impacts.
