Pre-operation Preparation
Equipment Status Check: Before starting the equipment, check that all components are intact, including motors, pumps, valves, and pipes. Ensure the equipment is undamaged, leak-free, and that the electrical system is functioning properly.
Water Quality Confirmation: Understand the water quality of the wastewater to be treated, including pH, COD, BOD, ammonia nitrogen, and other indicators, to adjust treatment process parameters.
Reagent Preparation: Prepare appropriate reagents according to the treatment process requirements, such as flocculants, disinfectants, and pH adjusters, ensuring the reagents are of qualified quality.
Start-up and Operation
Pre-start Flushing: Before officially starting the equipment, it is recommended to flush the equipment to remove impurities and residues from the pipes. Flushing time can be determined based on the equipment size and pipe length, but is generally no less than 5 minutes.
Opening the Inlet Valve: Slowly open the inlet valve to allow wastewater to gradually enter the equipment. Carefully observe the inlet flow rate and water quality changes to ensure the inlet water is stable and meets treatment requirements.
Starting the Treatment Units: Start each treatment unit sequentially according to the treatment process flow. For example, for equipment using the A²/O process, the anaerobic and anoxic tanks should be started first, followed by the aerobic tank. For equipment using the MBR membrane process, the circulation pump of the membrane module must be started first.
Adjusting Treatment Parameters: Treatment parameters should be adjusted in a timely manner according to water quality and treatment results. This includes adjusting aeration rate, reflux ratio, and reagent dosage to ensure stable and compliant treatment results.
Monitoring Operational Status: During equipment operation, the operational status should be monitored regularly, including motor temperature, pump flow rate, and valve opening. Simultaneously, the treatment effect should be observed, such as effluent quality and sludge characteristics, to facilitate timely adjustments to treatment parameters.
