It is the key to solve all problems to know exactly what kind of integrated sewage treatment equipment in hospital is.

  First, the process of integrating sewage treatment equipment in foreign trade hospitals

  Functions of medical wastewater pretreatment → first-class enhanced treatment → disinfection process:

  1. Pre-treatment part (water distribution canal and grid well are jointly built)

  In the pretreatment stage, a grid, a lifting pump room and a grit chamber are set. The main purpose of the grid is to remove large floating objects in sewage and intercept solid objects with a diameter greater than 20mm. The grit chamber is used to remove easily separated impurities, sand grains, etc. from sewage. Ensure the normal operation of the subsequent biochemical treatment process.

  2. Regulating pool

  According to the characteristics of small treatment scale and large change of water quality and quantity in this sewage treatment project, a regulating tank with appropriate size is set in the pretreatment section. The regulating pool is used for homogenization and equalization, protecting the normal and stable operation of the  subsequent biological treatment section, ensuring and improving the effective utilization rate of the biological reaction pool and making the process flow more flexible. There is one submersible sewage pump and one set of ultrasonic liquid level control system in the regulating pool, which can operate automatically.

  3. Coagulation sedimentation tank

  To treat key structures of sewage, biological denitrification and dephosphorization are carried out by using different functions of microbial flora, meanwhile, organic matters are removed, and sludge-water separation is carried out, and excess sludge is sent to sludge concentration.

  4. Disinfection pool

  The effluent from the sedimentation tank enters the contact tank for disinfection. Chlorine dioxide disinfection is adopted for disinfection, and the effluent from the contact tank reaches the discharge standard.

  Second, the current status of hospital sewage treatment

  At present, because of the epidemic situation, especially the local cabin hospitals have become important medical institutions, and the hospital sewage only treats the sewage in a single way. In the actual sewage treatment process, it is often accompanied by sewage treatment and the treatment and disposal of dehydrated sludge, which also directly affect the sewage treatment. When dealing with sewage, we only pay attention to the results of sewage treatment, but pay little attention to the impact of pollutants on the environment after sewage treatment. During the operation of the sewage treatment system, gaseous pollutants including NH3 and SO2 will be produced, and the treated water will also contain water pollutants such as N and P, while solid pollutants such as precipitation pollution and dewatered sludge will be produced by Han Hui. The direct treatment or discharge of these pollutants will have a certain impact on the environment.

  Third,Advantages of Integrated Sewage Treatment Equipment in Foreign Trade Hospitals

  1. The sewage treatment equipment of foreign trade hospital is integrated, with compact layout and small floor area, which can be buried under the surface of the earth. The surface can be used as a green or parking place, or on the ground to save the floor area.

  2. The process can be selected according to the characteristics of sewage and customers' needs. Many processes commonly used in isolation hospitals, such as MBR membrane biological process, AO process and A2O+MBR process, can be selected.

  3. The effluent quality is good and stable, and the effluent standard can reach Grade A standard.

  4. Fully automatic control system, convenient operation and management, no need for special care, and convenient maintenance.

  5. It has good denitrification capacity.

  6. No pollution, low noise and no peculiar smell.
