    The treatment of medical sewage requires multiple steps, including pre-treatment, biochemical treatment, advanced treatment, and disinfection treatment.

    What is Medical Sewage?

    Medical sewage refers to the sewage discharged from medical institutions, mainly composed of wastewater, waste, and waste liquid components. Medical wastewater contains a wide variety of drugs, mainly including various antibiotics, disinfectants, cleaning agents, anesthetics, neurotoxins, as well as biological pollutants such as surgical residues, blood clots, and excreta. Therefore, strict treatment and disposal must be carried out to prevent pollution to the environment and human health.

    The source and composition of sewage discharged by medical institutions are very complex, and the sewage contains a large amount of harmful substances such as infectious bacteria, viruses, and chemicals, which are highly harmful and infectious. Especially if the sewage discharged from infectious disease areas enters urban sewage pipelines or environmental water bodies without strict harmless treatment, it can cause water source pollution and outbreaks of infectious diseases, seriously endangering people's health.

    At present, the treatment process of medical wastewater mainly consists of primary sedimentation disinfection treatment and secondary biochemical disinfection treatment process. The specific treatment process can be selected based on the effluent requirements. When the treated wastewater can be discharged into the urban sewage official website, primary treatment is adopted, and when direct discharge is required, secondary treatment process is adopted.

    Technology Introduction

    1. The drainage of each ward and outpatient department is discharged into a septic tank through a drainage pipe network, and then treated in the septic tank before entering the subsequent water treatment structures. There are trace amounts of radioactive substances in the discharge water of the radiology department, which need to first flow into the decay pool to decay and then be discharged into the grid well.

    2. The effluent from the septic tank first flows into the regulating tank by gravity after removing large suspended and floating substances through the grid. The bottom of the regulating tank is equipped with a gas distribution pipe for stirring and pre aeration. After homogenizing the water quality and regulating the water volume in the regulating tank, the sewage is lifted by the lifting pump and enters the acidification and hydrolysis tank.

    3. In acidification and hydrolysis, the sewage can be homogenized and fully mixed with the reflux sludge of the sedimentation tank. The reflux activated sludge adsorbs organic matter in the sewage, which has the ability to decompose high molecular organic matter into small molecule easily biodegradable organic matter, and can more effectively remove pollutants;

    4. At the same time, a digestion zone is set up in the regulating tank to perform nitrification and denitrification of NH3-N in the digestion zone, which can effectively reduce NH3-N in the water. The sewage flows into the biological contact oxidation tank by itself for the degradation of COD and BOD5.

    5. The effluent from the biological contact oxidation tank contains a certain amount of aged and detached biofilm. These wastewater containing biofilm flows into the sedimentation tank, and after sedimentation, clean water flows into the disinfection tank. After disinfection and dechlorination, it meets the discharge standards.

    The sludge from the sedimentation tank partially flows back to the acidification hydrolysis regulation tank, and the excess sludge is discharged to the sludge tank for concentration. After being dehydrated by a plate and frame filter press, it is regularly cleaned, packaged, and transported out. The sewage removed from the sludge flows back to the regulating tank for reprocessing.

     

  • 1.Space saving: The integrated sewage treatment equipment adopts an integrated design, which does not require a large amount of land area and is compact in structure, which can save space.

    2.Long service life: The materials of the integrated sewage treatment equipment are corrosion-resistant, wear-resistant, and compressive, and advanced processes and equipment are used to ensure its long-term stable operation, with a service life of over 15 years.

    3.Good decontamination effect: The integrated sewage treatment equipment adopts various sewage treatment technologies, including physical, chemical, biological and other methods, which can remove various harmful substances from the sewage, meet national discharge standards, and maintain stable effluent quality.

    4.High degree of automation: Integrated sewage treatment equipment has a high degree of automation, which can be remotely monitored and managed through intelligent control systems, reducing manual intervention and operating costs.

  • The application range of integrated sewage treatment equipment is wide, and it can be applied to the treatment of domestic sewage such as residential communities, villages, office buildings, shopping malls, hotels, restaurants, sanatoriums, schools, hospitals, highways, railways, factories, mines, tourist attractions, and similar small and medium-sized industrial organic wastewater such as slaughtering, aquatic product processing, and food.

    Integrated sewage treatment equipment is particularly commonly used in villages and hospitals. This is because rural sewage has the characteristics of large changes in flow and water quality, and the advantages of integrated equipment such as small land area, small construction quantity, and short construction period make it the mainstream method of rural domestic sewage treatment.
