Hospital sewage refers to sewage discharged from hospitals (general hospitals, specialized hospitals, and other types of hospitals) into the natural environment or urban pipelines. Its water quality varies with the nature, size and location of the hospital. The amount of sewage discharged per bed per day is about 200-1000L. The main pollutants contained in hospital sewage are: pathogens (parasite eggs, pathogenic bacteria, viruses, etc.), organic matter, floating and suspended matter, etc. The total amount of bacteria in the untreated raw sewage reaches more than 108 / mL.
According to the characteristics of the above-mentioned sewage, hospital sewage treatment equipment generally uses A / O biochemical technology, combined with disinfection, inclined pipe sedimentation, MBR membrane equipment, which integrates biodegradation, sewage sedimentation, and oxidation and disinfection to meet sewage treatment of different discharge standards.
1. The equipment can be buried underground, and the surface above the equipment can be used for greening or other land.
2. The A / O biological treatment process has a smaller volume than the activated sludge tank, strong adaptability to water quality, good impact load resistance, stable effluent water quality and no sludge swelling. A new type of elastic three-dimensional filler is used in the tank, which has a large specific surface area, and the microorganisms are easy to hang and remove the film. Under the same organic matter loading condition, the organic matter removal rate is high, and the solubility of oxygen in the air in water can be improved.
3. The A / O pool adopts biological contact oxidation. The volume load of the filler is relatively low. The microorganisms are in the self-oxidation stage and the sludge production is small. It only takes more than three months (90 days) to discharge the sludge (suction with a dung cart). Shipping).
4. The entire equipment processing system is equipped with a full-automatic electrical control system, which is safe and reliable in operation. Usually, ordinary people do not need special personnel to manage, just need to maintain and maintain the equipment in a timely manner.
Scope of application:
