As urbanization accelerates, so does the number of wastewater treatment plants. In the process of sewage treatment, the agitator is one of the important equipment, which can evenly mix the impurities and harmful substances in the sewage, so that the sewage can get better treatment results. However, due to problems such as long use time and aging equipment, the agitator may be damaged or fall off. That's where salvage operations come in.
In sewage plants, salvage operations are usually done by frogman underwater installation operations. Frogman underwater installation operation refers to the installation, maintenance and dismantling of equipment by professional divers wearing diving equipment and going deep underwater. In sewage plants, the underwater installation of frogmen is mainly used for the salvage of agitators.
The salvage process of the agitator mainly includes the following steps:
1.Prepare tools and materials: Frogman underwater installation operations require the use of professional diving equipment and tools, such as wetsuits, goggles, shoes, flashlights, underwater cutting tools, etc. At the same time, it is also necessary to prepare the necessary materials, such as ropes, chains, tape, etc.
2.Safety preparations: Adequate safety preparations are required before the salvage operation can be carried out. First, a detailed survey and assessment of the plant's geographical location and underwater environment is required to determine whether there are potential safety hazards. Secondly, it is necessary to carry out necessary training and drills for frogman underwater installation operators to ensure that their operational skills and emergency response capabilities meet the requirements.
3.Diver launch: After safety preparation is completed, divers need to put on their diving gear and carry the necessary tools and materials into the water. In the water, divers need to perform detailed inspections and measurements of the equipment and piping of the sewage plant to determine the location and state of the agitator.
4.Mixer salvage: After confirming the location and status of the mixer, the diver needs to use an underwater cutting tool to remove the debris around the mixer and tie the chain or rope to the mixer. The diver will then need to perform a detailed inspection of the agitator using a flashlight and other tools to ensure that no other debris or dangerous items are present. Finally, the diver needs to slowly pull the agitator out of the water and hand it over to the staff on the surface.
5.Cleanup and repair: After the agitator has been salvaged, the equipment and piping of the wastewater plant need to be cleaned and repaired. If other equipment and pipelines are found to be damaged or aged, they need to be replaced or repaired in time. At the same time, the agitator needs to be inspected and repaired in detail to ensure that it can operate properly.
6.Recording and summarizing: After the salvage operation is completed, the entire process needs to be recorded and summarized. Records include important events during the salvage process, diver operations, equipment and pipeline status, and more. The summary is the evaluation and reflection of the entire salvage operation, so as to continuously improve and enhance in the future work.
In short, the underwater installation operation of frogman is one of the important means of agitator salvage in sewage plants. When carrying out salvage operations, it is necessary to pay attention to safety preparation, diver training and drills, inspection and measurement of equipment and pipelines, and salvage and cleaning and maintenance of agitators. Only in this way can the smooth progress of the salvage operation be ensured and the equipment and pipelines of the sewage plant can be kept in good operating condition.
