With the continuous development of China's science and technology, higher requirements are placed on the level of laboratory testing and research and development. In order to meet the needs of testing and research, it is necessary to improve the level of laboratory design and construction. Therefore, this paper studies the establishment of the laboratory design and construction standard system, which is undoubtedly of theoretical significance for promoting the stable and sustainable development of the laboratory.
Current status of laboratory design and construction standards
In the early days of creating various laboratories in China, the design concept that managers lacked was originally designed to meet the needs of some simple practices, focusing on the construction of laboratory water and electric wind and furniture. Since 2010, many laboratories have begun to integrate intelligent systems to meet the needs of the experiment. For example, in the laboratory, the installation of automatic exhaust air control system, laboratory VAV fume hood variable air volume control system, etc., these intelligent design, greatly improve the ventilation effect, while reducing energy consumption, energy saving and environmental protection. However, at present, in the process of design and construction in China, due to the different concepts of laboratory construction in the industry, only a small part of the intelligent control system is used, which fails to meet the needs of intelligent control of the laboratory.
Problems in the laboratory design and construction system
(1) Different laboratory design concepts
At present, in the design and construction of developed countries, more attention is paid to environmental protection, energy conservation, safety, comfort and sustainable development. In China, due to the late start of modern design and construction, most managers did not realize the importance of laboratory energy conservation, environmental protection and sustainable development. It is undeniable that comfort, environmental protection, energy conservation and safety are not only directly related to the work of laboratory personnel, but also have a huge impact on the natural environment. For example, the laboratory will produce certain experimental waste liquid after the experimental process or the completion of the experiment. If it is discharged into the natural environment without treatment, it will cause great harm to the natural environment and even affect the human body. It can be seen that it is better than strengthening the establishment of laboratory design and construction system standards to promote stable and sustainable development of the laboratory.
(2) Lack of standards for laboratory design and construction
Compared with foreign countries, the design, construction and construction of laboratories in China are uneven, and the level of design and construction is also very different. The technical level of many laboratory designers and builders is difficult to meet the needs of today's modern experimental design and construction. For example, in the design and construction of laboratory fume hoods, fume hoods are the basic equipment to ensure the normal operation of laboratory equipment and personnel safety, but in the actual design and construction process, some design builders pay too much attention to the operation of the equipment, ignoring the experiment. The safety of the room staff. Moreover, it is not aware of the importance of energy saving and environmental protection in laboratory fume hoods.
Establish a standard system for laboratory design and construction
(1) Follow the concept of laboratory design
In the process of design and construction, a unified design concept should be established. First, the safety of laboratory design should be highly valued, such as ensuring four basic standards for experimental design: (1) ensuring the safe storage of hazardous materials; (2) strictly protecting the safety of intellectual property; and (3) designing rooms and rooms in the laboratory. Controlled access control system; (4) Important rooms in the laboratory are not allowed without access and are accessible to anyone in the public area. Second, focus on the design of sustainable development in the laboratory. For example: design waste gas, wastewater treatment system, reduce the emission of hazardous waste; establish a laboratory waste liquid recycling system; design an intelligent control system, improve the use efficiency of laboratory water resources and electricity, and achieve the effect of laboratory energy conservation and environmental protection; Recyclable materials should be used in the supporting products in the laboratory. Finally, improve the comfort of the laboratory design. In order to realize the needs of the modernization and sustainable development of the laboratory, in the design and construction of the laboratory, the comfort of the experiment should be improved, and a comfortable public environment should be created for the laboratory staff to ensure the stability, key health and sustainable development of the laboratory. .
(II) Strengthening the establishment of laboratory design and construction standards
At this stage, there are more than 2,000 standards, involving 15 laboratory management, 23 laboratory safety, and more than 10 design standards for different departments, including aquatic animal quarantine laboratory and biosafety experiment. Room, measurement laboratory, central laboratory of machinery industry, science laboratory, etc. It can be seen that the standards for laboratory design and construction are relatively strict and extensive. In the process of laboratory design and construction, it is important to establish a unified standard system. For example, in the laboratory | DNA sequencing process, the sampling from the sample to the sequencing room strictly follow the rules of each process of the experiment to ensure the purity of the sample and the integrity of the data. In addition, in the design process of the laboratory space, it is necessary to ensure the comfortable space of the laboratory staff. In the lighting design, natural light should be utilized as much as possible, and the HVAC system should be properly designed to meet the needs of laboratory personnel.
In summary, this paper analyzes the status quo of laboratory design and construction standards, and proposes countermeasures to strengthen the establishment of laboratory design and construction standards and follow the concept of laboratory design for the problems existing in the laboratory design and construction system. However, the lack of standards for laboratory design and construction, and different laboratory design concepts still affect the quality of design and construction. Therefore, in the future work, it is necessary to strengthen the research on the establishment of the laboratory design and construction system, and make greater contributions to improving the level of laboratory design and construction and promoting the stable and sustainable development of the laboratory.
