The hospital laboratory is one of the core departments of a healthcare facility, providing doctors with diagnostic, research, and ** tools. However, the activities of hospital laboratories inevitably produce large amounts of toxic and harmful wastewater, which can cause serious harm to the environment and health if not effectively treated and treated.
At present, the technology and facilities of laboratory sewage treatment equipment in hospitals at home and abroad are constantly developing and improving. Next, we will explain the generation, nature and treatment equipment of laboratory wastewater.
Generation of laboratory wastewater.
Wastewater from hospital laboratories mainly comes from diagnostic samples, chemical reagents, pharmaceuticals, etc., which are generated from medical procedures. The chemical reagents and pharmaceuticals used in hospital laboratories in large quantities contain a variety of toxic substances and heavy metals, which can lead to water pollution and in severe cases, health hazards.
In addition, hospital laboratories often use detergents and petroleum-based substances, which can contaminate water sources. Therefore, laboratory effluents must undergo rigorous treatment before they can be discharged into the natural environment.
The nature of laboratory effluent.
Laboratory sewage contains a variety of harmful substances, heavy metals and chemical reagents, etc., which can be converted into relatively harmless sewage through proper treatment, but it is difficult to achieve, and the technology and cleaning ability of sewage treatment equipment are very demanding.
Laboratory wastewater mainly contains the following substances:
1) Pathogens and bacteria: Microorganisms spread in wastewater, and the pathogens and bacteria formed contain extremely strong transmissibility and infectivity.
2) Organic substances and organic solvents: such as toluene, benzene, phenol, chloroform, etc., these substances are harmful. According to statistics, the total content of organic matter in hospital wastewater exceeds the total content of various toxic pollutants.
3) Heavy metal ions: Lead, mercury, cadmium and other heavy metal ions are very harmful to the human body, these heavy metals are difficult to decompose, exist for a long time, and the harm of chronic poisoning is greater.
How to dispose of hospital laboratory effluent.
The following methods are mainly used for the treatment of laboratory wastewater:
1) Physical and chemical treatment: use solidification, precipitation, adsorption, filtration and other methods to remove suspended solids, color, dissolved organic compounds, heavy metals, etc. in wastewater, reduce the degree of sewage pollution, and realize water reuse.
2) Biotechnology: The use of organic matter in laboratory sewage for microbial treatment, through biological activities to remove difficult to treat organic matter in wastewater, can greatly improve the treatment effect of wastewater. The use of biotechnology can make wastewater more sustainable.
3) Other methods: such as precipitation process, advanced oxidation technology, membrane filtration, ozone oxidation and other methods, the purpose is to maximize the effect and treatment speed of laboratory wastewater treatment.
Epilogue. Wastewater treatment in hospital laboratories is a complex project that requires mastery of a variety of modern wastewater treatment processes. At the same time, relevant professional equipment and technology also need to be followed up in order to achieve high efficiency and economy of wastewater treatment, and reduce environmental pollution and human health risks.
Hospital laboratory sewage treatment equipment is a key link, only the use of advanced technology, the selection of appropriate treatment equipment, in order to ensure the treatment effect and quality.
