Medical wastewater treatment system

Generally, hospital sewage cannot be directly discharged. Except for domestic sewage, most of the water quality contains chemicals, radioactive substances, pathogens, etc. Therefore, hospital sewage needs to be treated with special methods to meet the discharge standards for discharge. The main parts and facilities that generate sewage include: diagnosis and treatment rooms, laboratories, wards, laundry rooms, X-ray image processing, animal rooms, isotope therapy diagnosis, operating rooms, and other drainage facilities. The composition and amount of wastewater generated by different departments and offices can vary greatly, such as heavy metal wastewater, oily wastewater, printing wastewater, radioactive wastewater, etc. Moreover, the wastewater generated by hospitals of different properties also varies greatly. The discharge of hospital sewage is more complex than that of general domestic sewage.

The medical sewage treatment process adopts the world's advanced biological technology for treatment, which integrates the removal of BOD5, COD, and NH3, and is currently an efficient sewage treatment equipment. Effectively replacing the national comprehensive discharge standard septic tank, the treated water quality can meet the discharge standards of GB18466-2005, the International Medical Institution Wastewater Discharge Standard.

Equipment characteristics:

1. Buried deep underground, the surface of the equipment can be used for greening and other purposes, without the need for building houses, heating, insulation, etc.
2. The sewage treatment equipment consists of secondary tanks, which are steel structures and coated with domestic interpenetrating network anti-corrosion coatings for corrosion prevention. A rubber network and a plastic network interpenetrating each other to form an interpenetrating polymer network. Can resist acid, alkali, salt, gasoline, kerosene, aging, abrasion, rust and rust. After applying this coating, the anti-corrosion life of the equipment can generally reach more than 15 years.
The A/O biological treatment process in sewage treatment equipment adopts a push flow biological contact oxidation tank, which has a better treatment effect than a fully mixed or two-stage series fully mixed biological contact oxidation tank. This biological oxidation tank has a smaller volume than the activated sludge tank, strong adaptability to water quality, and can withstand impacts with good performance. The effluent quality is also extremely stable. Adopting a new type of elastic three-dimensional material, it has a large actual specific surface area, convenient microbial biofilm formation and detachment, and high removal rate of organic matter, which can improve the solubility of oxygen in water in the air.
4. Due to the use of a biological contact oxidation tank in the A/O biological treatment process, the volume load of the packing is relatively low, and the microorganisms are in the self oxidation stage, resulting in less sludge production.
5. In addition to using conventional blower noise reduction measures, the sewage treatment equipment has also installed new sound-absorbing materials on the inner wall of the blower room, which can effectively reduce the noise generated by the equipment during use and mitigate noise hazards.
6. The equipment is equipped with a fully automatic system and an alarm system, which is highly reliable and does not require dedicated management. Maintenance and upkeep can be carried out after the equipment has been in use for a certain period of time.
