Quan Kun - Offers Laboratory Sewage Treatment Package - Effluent Quality Meets Standards - Easy Maintenance
The lab is a place for students to conduct experiments and explore, but the wastewater generated during the process is becoming an environmental pollution issue. Therefore, the use of wastewater treatment equipment in middle school laboratories is of great significance for environmental protection and healthy development. Wastewater treatment equipment can effectively process laboratory wastewater, reduce water resource waste, and ensure the cleanliness and safety of the laboratory environment. Carefully selecting the appropriate wastewater treatment equipment not only benefits environmental protection but also creates a good teaching environment for schools, promoting the improvement of students' scientific literacy and practical skills.
Equipment Type and Principle:
There are many types of laboratory wastewater treatment equipment, which can be divided into two main categories: biological treatment equipment and physical-chemical treatment equipment. Biological treatment equipment includes biological filters, aeration tanks, sedimentation tanks, etc., which solve the treatment issues of organic and inorganic substances in wastewater through the metabolic activities of biological organisms. Physical-chemical treatment facilities include sedimentation tanks, adsorption filters, UV sterilization units, etc., which can purify suspended solids, heavy metals, microorganisms, and more in wastewater through physical and chemical reactions.
The principle of biological treatment equipment is to utilize the metabolic activities of microorganisms such as bacteria and molds to decompose organic matter into harmless substances like water. The biological bacteria in a biofilter adhere to the filtering material, decomposing organic substances like urea, proteins, and hydrocarbons into non-harmful matter through growth and metabolism. The aeration pond further removes organic matter by sedimentation and increases oxygen supply to meet the metabolic needs of bacteria. The sedimentation pond effectively removes suspended solids, allowing organic matter in the water to decompose better in a static environment.
The principle of physical and chemical treatment equipment is based on the physical properties and chemical reactions between different substances. Sedimentation tanks are devices that separate and decompose suspended matter in water through centrifugal or gravity sedimentation. Adsorption filters are used to reduce the concentration of heavy metal ions in water by physically and chemically adsorbing metal ions. Ultraviolet disinfectors achieve sterilization and disinfection by destroying the DNA structure of bacteria and viruses through UV radiation.
