What are the standards and requirements for the design and installation of laboratory water supply and drainage system?

The design of laboratory drainage system is very important for the safety and hygiene of laboratory. As an important base for scientific research, laboratories must ensure safe and hygienic conditions. Especially for special laboratories, such as medical infectious virus laboratory and biological laboratory, safety is the most important. In these laboratories, many factors need to be considered in the design of drainage system to ensure that the experiment will not cause any potential harm to the environment and personnel.

The laboratory drainage system is a part of the three wastes treatment project in the laboratory, which should be determined according to the nature, concentration and quantity of wastewater discharged from production. Hazardous wastewater should be treated by wastewater and discharged after reaching the national discharge standard. The drainage equipment in the laboratory (area) and the equipment connected with the gravity backwater pipeline must be equipped with a water seal device below its outlet, and the height of the water seal should not be less than 50 mm, and the drainage system should be equipped with a ventilation device. Drainage risers should not pass through laboratories (areas) with air cleanliness of 100 and 10000; When the drainage riser passes through other laboratories (areas), no inspection port should be set.

Design and installation requirements of laboratory water supply and drainage system

1, the water supply and drainage system of the laboratory should be scientifically designed to ensure that the drinking water source is not polluted. If the source of experimental water is different from that of drinking water, the taps for drinking water and experimental water should be marked separately to avoid confusion.

2. The laboratory building should be equipped with standby water source. When the water supply of public tap water system is insufficient or stopped, the standby water source should be able to ensure the normal supply of various instrument cooling water, distiller water, distillation bottle condenser water and eye washer water.

3, water supply and drainage system should be consistent with the laboratory module, reasonable layout, easy to maintain, pipes should be as short as possible, to avoid cross.

4. Water supply pipes and drainage pipes should be arranged along walls, columns, tube wells, test bench cavities and village boards in fume hoods. , and expensive instruments and equipment should not be arranged above it, nor should it be close to articles that decompose rapidly in water, are easy to damage or cause combustion and explosion;

5. Generally, the water pipes in the laboratory can be laid with bare surface and concealed as far as possible in the laboratory with high safety requirements. All concealed pipes shall be equipped with manholes at the control valve for maintenance.

6. The water supply and drainage system should be designed flexibly, and some facilities should be reserved to ensure the reliability and continuous operation of the laboratory.

7. The down-feed horizontal water supply main pipe should be laid above the bottom walkway or below the basement roof;

8. The horizontal water supply pipe with upward delivery and downward delivery should be laid in the technical layer of the top-floor pipeline or above the top-floor walkway: it can be laid on the roof of the frost-free area, and valves should be installed on each branch of the water supply pipe leading to the laboratory.

9. The location of laboratory water points must be scientifically located and laid out in advance, and the water points should be set against the wall as far as possible to facilitate the setting of water points and meet the needs of future transformation.

In addition, under the requirements of the country to vigorously promote green development, the demand for scientific purification of laboratory waste gas, recycling of waste water and upgrading of standards has also increased accordingly. The laboratory construction team, which aims to build automatic and intelligent laboratory equipment, has been widely concerned and highly recognized by the industry.

Among them, as a well-known enterprise in the laboratory industry, the professional engineer team of Big Oak Group, a professional service provider in the field of smart laboratories, has actively built a green laboratory, laying a solid foundation for researchers to provide an efficient and environmentally friendly environment.

Big Oak Group has the service ability of independent research and development, design, production and laboratory system engineering. Fifteen years of experience in laboratory project construction site management, providing engineering construction services for high-end customers in various industries 1500+ all over the country, actively participating in laboratory construction, helping the laboratory to do a good job in laboratory waste gas and wastewater treatment through scientific and technological means, helping to fill in the shortcomings of green development, and gaining full recognition and trust from customers.
