english 1. Preparation before operation
Check the various components of the flotation equipment in detail to ensure that the dissolved air pump, aeration device, scraper, etc. are not loose or damaged to avoid sudden failures during operation. At the same time, carefully check whether the pipeline connection is tight to prevent air leakage or water leakage, which will affect the flotation effect. In addition, according to the water quality of the wastewater to be treated, reasonably adjust the type and dosage of flotation agents, flocculants and other agents, and determine the optimal parameters through small tests to lay a good foundation for formal operation.
2. Monitoring during operation
Closely monitor the operating status of the equipment, pay attention to key parameters such as dissolved air pump pressure, aeration volume, and scraper speed, and make timely adjustments once abnormalities are found. For example, if the dissolved air pump pressure is too high or too low, it will affect the dissolved air efficiency and bubble quality, and the cause must be immediately investigated and resolved. At the same time, observe the bubble generation and scum layer status in the flotation tank. If the bubble size is uneven and the scum does not float smoothly, the operating conditions should be optimized in time. In addition, regularly test the inlet and outlet water quality, dynamically adjust the operating parameters according to the changes in water quality, and ensure that the treatment effect is stable and meets the standards.
3. Daily maintenance and safety
Perform regular maintenance on the equipment, clean the aeration head, dissolved air releaser and other easily blocked parts, and prevent impurities from accumulating and affecting the performance of the equipment. For transmission parts, such as chains and bearings of scraper machines, lubricating oil should be added regularly to reduce wear and extend service life. In terms of safety, operators must strictly abide by operating procedures, wear protective equipment, avoid contact with chemicals or injuries caused by equipment operation. At the same time, keep the operating area well ventilated to prevent safety accidents caused by harmful gases emitted by wastewater.
