Embodiment 1

[0028] Embodiment 1: A hospital wastewater treatment system, including a grid, a regulating tank, a sedimentation tank 1, a disinfection tank 1, a biological contact oxidation tank, a sedimentation tank 2, and a disinfection tank 2 connected in sequence. The hospital wastewater treatment system also includes a septic tank connected to the grill and a pre-sterilized tank connected to the grill. The wastewater from the non-infected area in the hospital wastewater flows into the septic tank, and the wastewater from the infected area flows into the pre-disinfection tank. The second ozone generator is installed in the pre-disinfection tank, and the ozone generated by the second ozone generator is passed into the pre-disinfection tank along the pipeline.

[0029] One side of the disinfection tank 1 is provided with a water inlet connected to the sedimentation tank 1, and the other end of the disinfection tank 1 is provided with a water outlet connected with the biological contact oxi...

Embodiment 2

[0034] Embodiment 2: Hospital waste water treatment system. The difference from Embodiment 1 is that the ultrasonic frequency emitted by the ultrasonic generator is 33KHz.

Embodiment 3

[0035] Embodiment 3: Hospital wastewater treatment system, the difference from Embodiment 1 is that the wavelength of ultraviolet light emitted by the ultraviolet lamp is between 330nm-370nm.

Abstract

The invention discloses a hospital wastewater treatment system. The hospital wastewater treatment system comprises a grid, a regulating tank, a settling tank I, a disinfecting tank I, a biological contact oxidation tank and a disinfecting tank II, wherein a carrier, a nano titanium dioxide-ferroferric oxide composite material loaded on the carrier, an ultraviolet lamp and an ultrasonic generator are arranged in the disinfecting tank I. The hospital wastewater treatment system has the following advantages and effects that the grid is adopted for removing solid pollutants in hospital wastewater, then the hospital wastewater enters the settling tank I to be subjected to internal settlement treatment after flowing through the regulating tank, bacteria in medical wastewater are killed in the disinfecting tank I, then the wastewater enters the biological contact oxidation tank, organic matters in the hospital wastewater are degraded in the biological contact oxidation tank, then the hospital wastewater enters into the disinfecting tank II, disinfection treatment is carried out, and bacteria and viruses in the hospital wastewater are killed, so that good bactericidal performance and good hospital wastewater treatment effect are achieved.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a hospital wastewater treatment system. Background technique [0002] The hospital is a place where patients' activities are relatively concentrated. The source and composition of hospital wastewater are complex, containing a large number of pathogenic bacteria, viruses and chemical agents. It has the characteristics of space pollution, acute infection and latent infection, and is very harmful. If hospital wastewater containing pathogenic microorganisms is discharged into urban sewers or environmental water bodies without disinfection treatment, it will often cause water pollution, cause various diseases and infectious diseases, and seriously endanger people's health. [0003] In the process of treating hospital wastewater, ultraviolet disinfection technology is one of the physical disinfection methods, with spectral sterilization ability, it does not produce disinfection by-p...
