With the rapid development of science and technology, the level of medical care has been greatly improved, but at the same time, it has also brought many new problems. One of them is the sewage problem in the hospital laboratory. The hospital laboratory is one of the most important departments in the hospital and a critical area for hygiene and safety. The laboratory is not only a place for sample processing, but also for the disposal of reagents, samples and effluents. In this process, a large amount of sewage is generated. If left untreated and cleaned up, it will cause great harm to the environment. Therefore, the sewage treatment equipment of the hospital laboratory is particularly important.
Hospital laboratory wastewater has the following characteristics:
First of all, the hospital laboratory has a large output of sewage. Laboratories in hospitals generally operate around the clock, so the amount of wastewater produced by the laboratories is considerable. Some wastewater flows in a laboratory may be larger than normal domestic wastewater.
Secondly, the quality of the sewage from the hospital laboratory is poor. Due to the nature of the laboratory's work, the wastewater produced contains complex chemicals, microorganisms and other components, so it is relatively difficult to treat.
Finally, hospital laboratories have high requirements for wastewater treatment. Because the area where the hospital laboratory is located needs to meet health and safety requirements, the treatment of this wastewater is not as casual as that of other environmental treatment departments. We need high-quality equipment to clean up the wastewater and convert it into the final extraordinary.
Because of these characteristics, we need a high-quality set of equipment to treat wastewater from hospital laboratories. Among them, the sewage treatment equipment of the hospital laboratory is one of the very important equipment. They can filter harmful substances from wastewater and then convert it into clean water that can be reused. Here are four commonly used hospital laboratory wastewater treatment equipment: physical, chemical, biological, and electrochemical.
Physical treatment mainly includes precipitation, filtration, and membrane technologies. Sedimentation is the use of gravity or centrifugal force and other natural forces to condense it into the most compact precipitate, filtration through filter paper, filter membrane adsorption, filtration and other physical treatment. Membrane technology is based on sedimentation and filtration, controlling the extraction of substances or leaving unwanted substances in the effluent.
Chemical treatment generally adopts redox, precipitation, neutralization, etc. Redox works by changing the redox state of certain substances in solution to achieve the purpose of removing substances. Sedimentation is the addition of suspended particles in wastewater to the opposite agent, which can make the suspended particles accumulate and become larger sediments and precipitate from the water.
Biological treatment is the conversion of organic matter in wastewater into CO2 and water through artificial biological systems or natural biological processes. At the same time, the biological treatment process is relatively stable and reliable, which can make the water quality stable and improve for a long time.
Electrochemical treatment uses the principle of electrolysis to produce redox reactions in the electrolytic cell to remove organic and heavy metal substances. Electrochemical technology is highly efficient in treating wastewater, but its equipment investment and operating costs are also relatively high.
In general, it is the responsibility of medical institutions to treat hospital laboratory wastewater properly and effectively to reduce the impact and harm to the environment. Through physical treatment, chemical treatment, biological treatment and electrochemical treatment, high-quality hospital laboratory sewage treatment can be obtained. Therefore, researching and manufacturing high-quality and reliable hospital laboratory sewage treatment equipment is essential for the future development of hospitals.
