Hospital wastewater treatment equipment is a key facility to ensure that the wastewater generated during hospital operations is effectively treated. These devices are designed to remove pollutants from wastewater through specific processes and equipment to meet national and local discharge standards.
First of all, the screen equipment plays a vital role in the sewage treatment process. Hospital sewage may contain large particulate matter such as various medical supplies and pharmaceutical residues, which will affect the subsequent treatment process if these substances are not removed in time. The screen equipment uses its special structure and function to effectively screen these large particles from the sewage and provide convenience for the subsequent treatment process.
Secondly, sedimentation tanks also play a key role in wastewater treatment. It uses gravity to make the suspended matter in the sewage naturally settle to the bottom of the tank, so as to achieve the clarification of the sewage. After the treatment of the sedimentation tank, the quality of the sewage has been significantly improved, which has laid a good foundation for the subsequent treatment process.
Activated sludge treatment equipment is a common equipment in hospital sewage treatment. It uses the decomposition of organic matter by microorganisms to achieve the purpose of purifying sewage. In activated sludge treatment plants, a large number of bacteria and microorganisms grow and multiply by engulfing the organic matter in the sewage, converting the organic matter into harmless substances such as carbon dioxide and water.
Similar to activated sludge treatment equipment, biofilm treatment equipment also uses microorganisms to decompose organic matter. However, the microorganisms in the biofilm treatment plant grow on a fixed biofilm, rather than being suspended in the wastewater. This treatment method is relatively stable and the microorganisms are more active.
Chemical oxidation equipment uses chemical oxidants to oxidize specific organic substances in sewage. Common chemical oxidants include potassium permanganate, hydroxides, etc. These chemical oxidants are able to oxidize organic matter to harmless substances such as carbon dioxide and water.
Advanced oxidation technology equipment is a kind of high-efficiency sewage treatment equipment, which uses free radicals generated by oxidants to remove pollutants in sewage. This equipment is capable of removing refractory organic substances and certain heavy metal ions. Advanced oxidation technology equipment has a wide range of application prospects in the field of sewage treatment.
Reverse osmosis equipment is a kind of physical treatment equipment, which separates the ions, molecules and particles in sewage from the membrane surface through high pressure. This equipment is suitable for the removal of heavy metals, dissolved salts and organic substances from wastewater. Reverse osmosis technology is increasingly used in the field of wastewater treatment.
Finally, UV disinfection equipment is equipment used to kill microorganisms such as bacteria and viruses in sewage. It uses the energy of ultraviolet rays to directly kill microorganisms and ensure that the treated sewage will not cause secondary pollution to the environment and humans.
To sum up, hospital sewage treatment equipment is diverse and has its own characteristics. Depending on the nature of the effluent and the discharge requirements, different treatment equipment and processes can be selected. At the same time, hospital sewage treatment is a comprehensive project, which needs to consider factors such as equipment support, operating costs and treatment effects. Only by selecting the right equipment and processes can we ensure the efficient and compliant discharge of hospital wastewater treatment.
