Abstract

The invention relates to a medical wastewater disinfection and sterilization device. The device comprises the following units: a mechanical filtering unit and a dissolved air generating unit, wherein the dissolved air generating unit is arranged at the downstream of the mechanical filtering unit and is used for dissolving air to promote dissolved oxygen in wastewater; a reactor unit and a micro-nano bubble releasing and aerating unit, wherein the micro-nano bubble releasing and aerating unit is arranged at the downstream of a dissolved gas generating unit, and the outlet end of the micro-nano bubble releasing and aerating unit extends into a reactor shell, the shell is provided with at least one water outlet channel and at least one particle collecting and discharging channel, a cathode unit and an anode unit are fixedly arranged in the shell, and an ultraviolet lamp unit is fixedly arranged in the anode unit in a staggered manner; and a liquid level adjusting unit arranged in the shell, and the mechanical filtering unit, the dissolved air generating unit, the cathode unit, the anode unit, the ultraviolet lamp unit electric control component, the liquid level adjusting unit electric control component and a sensor for acquiring the operating parameters are electrically connected with an electric cabinet unit. Through the serial use of two technologies of filtering and micro-nano bubble floating, the change of the particle contents in the water is solved, and the turbidity is improved.

Description

technical field [0001] The invention relates to a waste water treatment device, in particular to a medical waste water disinfection and sterilization device. Background technique [0002] Before the treated medical wastewater is discharged into the receiving water body, it must be sterilized to meet the water quality requirements for medical wastewater discharge. During the sterilization process, the relative resistance of microorganisms increases roughly in the following order: bacteria, viruses and parasitic cysts. Sodium hypochlorite, chlorine and chlorine dioxide are mostly used at present; a single ozone or ultraviolet light is used for sterilization and disinfection. The former can kill viruses, but it cannot control parasitic contamination. In addition, chlorine can form halogenated disinfection by-products, and inadvertent storage and handling of on-site chemicals can present an explosion hazard. The latter ozone has a very short half-life after being dissolved in...
