As an indispensable laboratory environment in the field of science and technology, physical and chemical laboratories play an important role in daily scientific research and learning. However, in the laboratory, the effluent produced is also a problem that cannot be ignored. It not only pollutes the environment, but also poses a threat to human health. Therefore, laboratory sewage treatment equipment is particularly important.
Generally speaking, the sewage of physical and chemical laboratories is mainly composed of chemical reagent waste liquid, organic reagent waste liquid, etc., and the harmful substances in it are harmful to the environment and the human body. Traditional treatment methods are mainly through physical and chemical means, such as physical precipitation, biodegradation, etc. However, these methods work well, but they also have certain limitations, such as large equipment, time-consuming, energy-consuming, and low efficiency.
As a result, some new types of physical and chemical laboratory sewage treatment equipment have emerged, which are mainly treated by nanofiltration, reverse osmosis and other technologies, which have the following advantages.
High efficiency. The new type of physical and chemical laboratory sewage treatment equipment adopts nanofiltration, reverse osmosis and other technologies for treatment, and has the characteristics of high efficiency. These devices are able to filter out harmful substances in wastewater in a short period of time and achieve rapid treatment of wastewater.
Save energy. 
Compared with traditional physical and chemical methods, the new physical and chemical laboratory sewage treatment equipment can save more energy. This is mainly due to the fact that nanofiltration, reverse osmosis and other technologies can be treated at low pressure, which can greatly reduce the energy consumption of the equipment.
No secondary pollution.
Compared with traditional physical and chemical methods, the new physical and chemical laboratory sewage treatment equipment is more environmentally friendly and will not produce secondary pollution. This is mainly due to the fact that these devices are able to completely filter out harmful substances in the wastewater and do not cause harm to the environment.
It's easy to use. Compared with the traditional physical and chemical methods, the operation of the new physical and chemical laboratory sewage treatment equipment is also simpler. These devices do not require complex operating processes, and only need simple operations to achieve wastewater treatment.
In general, the new physical and chemical laboratory sewage treatment equipment has many advantages such as high efficiency, energy saving, no secondary pollution, and simple operation, which can meet the needs of sewage treatment in the laboratory environment. However, it should be noted that these devices need to be regularly maintained and upheld to ensure the normal operation of the equipment. At the same time, it is necessary to operate in strict accordance with the manual during use to prevent the equipment from being misoperated or misused.
To sum up, the new physical and chemical laboratory sewage treatment equipment should be widely used. They are not only environmentally friendly, efficient and energy-saving, but also simple to operate and more convenient to use. We should encourage laboratories to use these equipment for sewage treatment, so as to improve the overall level of the laboratory environment and ensure the normal progress of our scientific research and learning.
