Medical wastewater originates from hospitals and other medical institutions, which may contain a large number of pathogenic microorganisms, as well as various drugs, laundry detergent, soda ash, radioactive isotopes, cotton swabs, gauze, etc. Its COD is close to the numerical range of domestic wastewater, but fluctuates greatly The BOD/COD of sewage is generally around 0.5, indicating good biodegradability. However, biological safety is an important issue and cannot be treated like regular sewage.

In order to ensure that hospital sewage treatment meets discharge standards and greatly reduce the risk of sewage treatment stations, according to the "Design Specification for Hospital Sewage Treatment"

According to the requirements of CECS07:2004, hospital sewage should meet the following requirements:

1. The sewage from hospital wards and non wards should be separated, and hospital sewage and waste should be strictly controlled and separated. It is not allowed to dispose of hospital generated waste into the sewage system at will.

2. Various special drainage systems in hospitals should be collected separately and treated with different pre-treatment measures before being discharged into the hospital's sewage treatment system.

The sterilized sewage is sent to the biological filter tower for aerobic biochemical treatment. During the system start-up process, bacterial strains (such as activated sludge from other domestic sewage) should be introduced into the biological filter tower and domesticated and cultivated for a certain period of time to form activated sludge and microbial communities suitable for the system treatment. As the sewage entering the biological filter tower undergoes sterilization treatment, this domesticated activated sludge can more effectively promote microbial reproduction, maintain a good microbial community, and improve treatment efficiency

Due to the fact that only some equipment needs to be enclosed, it can effectively save investment costs and operational inconvenience caused by system closure, especially for biological filter towers that can use existing technology. Compared to fully enclosed systems, this greatly facilitates users, and because the disinfection and sterilization material is only sewage, there is no need to collect and disinfect exhaust gas under fully enclosed systems, greatly reducing process composition and equipment investment.

The adsorption device is installed inside the device body, which is conducive to adsorbing small pollutants and bacteria in medical sewage, and is conducive to the first disinfection of medical sewage. The setting of the first rigid filter screen and the second rigid filter screen is conducive to distinguishing large and medium-sized liquid pollutants in medical sewage, so that users can separate them for treatment. The heating wire is installed inside the liquid collection box, boiling the sewage liquid and using high-temperature disinfection to sterilize and disinfect the medical sewage. The stirring rod is installed on the outer ring of the rotating shaft in a rotating manner, which is conducive to stirring the pollutants in the medical sewage and accelerating the filtration rate of medical sewage pollutants. The first needle rod and the second needle rod are installed at the lower end of the hydraulic rod, which is conducive to the first rigid filter screen and the second needle rod. The second rigid filter is unblocked, Avoid clogging of the first rigid filter and the second rigid filter.

Inspection before equipment linkage debugging

1. The rotation and operation of fans and motors in the idle testing equipment room, as well as the reliability of the operation of components in the electrical control cabinet.

2. Check the lubricating oil filling status of the fan in the equipment room.

3. Check the firmness of the internal and external pipeline connections.

4. Check the connection status of internal and external circuits.

5. Inject sewage into the integrated sewage treatment equipment and check for any leakage at the connections of each pipeline

6. Start the fan and check the operation of all equipment in the domestic sewage system for any abnormal vibration, noise, etc.
