If there are defects and hidden dangers in the construction technology of the water tower writing in the construction of the safety system of aerial work, it must be rectified in timeIf there is a risk to personal safety, the operation must be stopped. Any object that may fall onto the construction site should be removed or secured beforehand. The materials used in high-altitude work should be stacked smoothly and should not obstruct passage and loading and unloading. Tools should be stored in a tool bag;Walkways, access boards, and climbing equipment should be cleaned at all times during operationDismantled items, remaining materials and waste materials should be cleaned up and transported away in a timely manner, and should not be discarded or littered.

Pre-construction preparationsBefore proceeding with the water tower maintenance construction, a series of pre-construction work needs to be carried out to ensure the safety of the construction process. safety measures, development of safe operating procedures, and training of personnel involved in maintenance and construction. Prepare the necessary safety equipment, such as hard hats, protective glasses, gloves, etc. Post safety warning signs at construction sites to alert others. Membrane fouling during NMBR operation depends primarily on membrane properties, operating conditions (temperature, water flux, HRT and SRT), hydrodynamics, and sludge characteristics. The LIN study reported that when operating under the same hydrodynamic conditions, the filtration resistance of the system at high temperatures was about 5 1 times higher than that of the system at medium temperatures. This is due to the accumulation of SMP and fine flocs in large quantities at high temperatures. As HRT decreases, SMP accelerates, while longer SRT reduces particle flocculation and particle size, exacerbating membrane fouling, Huang reported. By optimizing the operating conditions, membrane fouling in NMBR can be effectively mitigated to a certain extent. 
Before the start of the work, clarify the overall goal of safety production, and gradually formulate safety objectives and corresponding safety measures according to the overall goal to ensure the realization of safety objectives. 
Pre-construction preparation: check whether the raw materials have a certificate, whether the standards of the raw materials meet the requirements, and the outdoor construction must build a house to protect the gray sand and rain and dew. The temperature of the construction site. The temperature should be 15-30, and the temperature should not be less than 80%. Use wax-free fiberglass cloths and prepare construction tools such as scales, containers, stirring rods, paint brushes or razors, spoons and measuring cups, scrapers, scissors, rulers or tape measures, which must be kept dry and clean. Preparation of work and safety equipment as well as firefighting equipment. Use putty to repair the part: If the base layer is uneven, you can use putty to repair it first, and then brush it after drying. The finished putty should be stirred evenly before use, and if the putty is thicker, it can be fixed with water. Use only putty: the base layer is not smooth enough, and the hemp surface must be completely filled with putty. When working, the material is placed on a pallet and scraped with a spatula or rubber scraper, the windows should scrape the ceiling, and the walls should be scraped first and then scraped. Each layer of putty should not be too thick. After the putty is dried, it should be sanded with sandpaper in time, and there should be no ripples and scratches, and the dust should be removed after sanding. Use primer: Use primer evenly, if the color is stronger, you can dilute it with the necessary water and apply it evenly with a brush, being careful not to brush the bristles or use it too thickly.
