Hospital wastewater treatment device

Abstract

The invention discloses a hospital wastewater treatment device, which comprises a wastewater inlet, a septic tank, a primary sedimentation tank, a partition plate, a delivery pump, a biological fluidized bed, a filler, an ultraviolet lamp tube, an oxidation bed, a quartz tube, a filter net, a waste gas treatment box, a plasma reactor, an activated carbon adsorption plate, an air outlet, a switch valve, a secondary sedimentation tank, a sludge pump, a mixing motor, a water outlet, a film reactor, a film assembly, an ozone generator, a disinfecting tank, a mixing blade, a sodium hypochlorite generator, a sludge bucket, an air-lift pump, a fan, a grating, a conveyor motor and a conveyor belt. By adopting a three-chamber septic tank, the wastewater is corrupted and broken, and meanwhile, internal solid wastes are intercepted and output by adopting the mode of the conveyor belt, so that the hospital wastewater treatment device is convenient and fast, and high in treatment capacity; ozone disinfection and sodium hypochlorite sterilization are sequentially carried out by adopting the ozone generator and the sodium hypochlorite generator under the mixing condition after treatment of the biological fluidized bed, so that removal of a pathogen in the wastewater is achieved.

Description

technical field [0001] The invention relates to a waste water treatment device, in particular to a hospital sewage and waste water treatment device, belonging to the technical field of waste water treatment equipment application. Background technique [0002] Hospital sewage refers to the sewage discharged by hospitals to the natural environment or urban pipelines. The water quality varies with the nature, scale and location of different hospitals. The main pollutants contained in hospital sewage are: pathogens, organic matter, floating and suspended matter , radioactive pollutants, etc. Therefore, it must be treated before it can be discharged, especially the sewage discharged from infectious disease wards such as hepatitis must be disinfected before it can be discharged. [0003] Most of the existing hospital sewage uses chemical reagents for sterilization and disinfection. This method is complicated to operate and low in efficiency. It is difficult to cleanly remove patho...

Problems solved by technology

[0003] Most of the existing hospital sewage uses chemical reagents for sterilization and disinfection. This method is complicated to operate and low in efficiency. It is difficult to cleanly remove pathogens in water bodies. In addition, existing sewage treatment equipment produces The exhaust gas is directly discharged, which causes serious air pollution and loses the essential meaning of treatment; therefore, a hospital sewage and wastewater treatment device is proposed to solve the above problems
