Design steps and key points of laboratory water supply and drainage system:

1. understanding of laboratory needs

Laboratory water supply and drainage system is composed of water supply part and drainage part, water supply system including laboratory water supply system, life water supply system and fire water supply system; drainage system should be based on the composition, nature, flow rate and discharge law of the wastewater discharged from the laboratory and set up the corresponding drainage system.

Before the design must first consider the characteristics of the laboratory and experimental needs, in order to develop the most appropriate design according to the needs. Because different laboratories have different water and drainage requirements for laboratories, the cooling circulating water quality of experimental instruments should meet the different requirements of various instruments for water quality, such as chemical laboratories need to consider the treatment of corrosive substances, biological laboratories need to meet the treatment requirements of biological waste liquid, and so on. In addition, the laboratory building should also be provided with a backup water source. When the water supply of the public tap water system is insufficient or stopped, the backup water source can ensure the normal supply of cooling water for various general instruments, eye washer water, distiller water, and distiller condenser pipe water.

2. reasonable layout planning

In the design of water supply and drainage system, reasonable pipeline planning is also very important, such as the corner as little as possible, in order to prevent the blockage of impurities; in the arrangement should be relatively concentrated, so that it is more convenient for maintenance after failure. In addition, the convenience of equipment connection should be considered in the design to ensure that the pipeline layout is reasonable and the connection is smooth, so that the liquid and wastewater can be smoothly transmitted between the various areas in the laboratory to avoid causing bacterial growth or odor.

Among them, the water supply mode is divided into outdoor water supply pipe network direct water supply, high-level water tank water supply, pressurized water pump and high-level water tank water supply, etc. The pipe running mode is generally ceiling hoisting pipe, which is led to the laboratory water point along the wall. Drainage pipe way is generally the same layer drainage, different layer drainage. It is worth mentioning that a reasonable pipeline layout can avoid the possibility of cross-infection and improve the efficiency of laboratory work.

3. scientific and reasonable equipment

When choosing equipment, consider the actual needs of the laboratory and the quality and performance of the equipment. For example, for chemical laboratories, pipes and equipment that can resist corrosion should be selected; for microbiology laboratories, equipment that can meet sterility requirements should be selected. Only by selecting the appropriate equipment can the normal operation of the laboratory and the accuracy of the experimental results be ensured. At the same time, during the installation process, it is necessary to pay attention to the connection and sealing between the water supply and drainage pipes and other equipment to avoid water leakage and sewage leakage.

4. Maintenance Management

Regular inspection and maintenance of equipment is an important link to ensure the normal operation of the system and avoid failure. Regular inspection helps to find potential problems and repair them in time, so as to avoid the impact on laboratory work due to equipment failure. For example, the management and maintenance of water tanks, pools, water tanks and sanitary ware, whether the inner surface of the box is smooth and clean, whether there are any factors that pollute the water quality, whether there is corrosion and water leakage in the drainage pipe, and regularly maintain and clear the pipes to ensure the cleaning ratio and prevent dirt regeneration. In addition, by monitoring the operation of the system, problems can be found and solved in time to avoid failures and accidents in the water supply and drainage system.

Based on the above aspects, it is said that only through scientific design and reasonable installation, the laboratory water supply and drainage system can provide more reliable support for the operation of the laboratory. In reality, this kind of engineering design and installation requires a high degree of professionalism, so it often requires an experienced professional team to plan and execute.
