Hospital wastewater treatment equipment
Hospital wastewater treatment equipment adopts international advanced biological treatment technology. Based on summarizing the operation experience of domestic wastewater treatment equipment at home and abroad and combining with its own scientific research results and engineering practice, a complete set of organic wastewater treatment equipment that can be buried is designed. It integrates the removal of BOD5, COD and NH3-N, and has the advantages of stable and reliable technical performance, good treatment effect, low investment, automatic operation, convenient maintenance and operation, no floor area, no building, no heating and heat preservation, etc. Flowers and grass can be planted on the ground without affecting the surrounding environment.
This device is generally buried under the surface of the earth, and adopts a secondary biological contact oxidation treatment process. Its treatment effect surpasses that of a fully mixed biological oxidation tank, and has high adaptability to water quality and ensures the stability of water treatment. The equipment adopts a new type of strong elastic three-dimensional filler in the tank, which has the function of strong removal of organic substances in sewage. After oxidation treatment, the equipment produces less sludge and only needs to be discharged once in 90 days. In order to avoid the occurrence of breeding and spreading of released bacteria, the water quality must be deeply disinfected. At present, the most widely used disinfection technologies are ultraviolet disinfection, chlorine dioxide disinfection and ozone disinfection. Hospitals need to choose according to the characteristics of sewage quality and discharge amount.
1. The surface area of the equipment buried underground can be used as green land to save the occupied area for the hospital.
2. The sewage integrated equipment is made of corrosion-resistant and oxidation-resistant materials, with long service life, thus saving operating costs for the hospital.
3. The biological contact oxidation tank combined with layer-by-layer filtration and disinfection device has good sewage treatment effect and solves the problem of pathogen transmission.
4. This equipment has good deodorization effect and small amount of sludge, and will not cause other pollution hazards to the environment. 5. Fully automatic control system, installation of damage alarm system, no need for manual supervision, saving labor input.
