Residual chlorine controllable environment-friendly medical wastewater deep disinfection and sterilization device

Abstract

The invention provides a residual chlorine controllable environment-friendly medical wastewater deep disinfection and sterilization device. The device comprises a pretreatment module, a solid-liquid separation module, a wastewater disinfection module, a wastewater sterilization module, a residual chlorine monitoring module and a residual chlorine adding module, wherein the pretreatment module, the solid-liquid separation module, the wastewater disinfection module and the wastewater sterilization module are connected in sequence; the residual chlorine monitoring module and the residual chlorine adding module are arranged at the wastewater disinfection module; a residual chlorine adding module and a residual chlorine monitoring module are arranged at the wastewater disinfection module for two purposes, firstly, the residual chlorine content in the water body is detected through the residual chlorine monitoring module, and when the residual chlorine content in wastewater is detected to exceed the standard, the neutralizing medicine can be added into the disinfection box so that the purpose of controlling residual chlorine is achieved, the automation degree is high, and the detection result is accurate, secondly, a plurality of hollow crank arms are arranged on the unfolding type spraying disc, the spraying area of the sodium hypochlorite solution in the disinfection box can be completed by unfolding or combining the hollow crank arms, the mixing uniformity of the sodium hypochlorite solution and the water body can be increased, the disinfection efficiency is improved, and disinfection dead angles are avoided.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment equipment, and in particular relates to an environment-friendly deep disinfection and sterilization device for medical wastewater with controllable residual chlorine. Background technique [0002] With the increase of national health awareness and the improvement of residents' living standards, my country's medical and health services have increased year by year. Small medical institutions such as health centers, clinics, and health stations are also increasing year by year. The common characteristics of these institutions are that the surrounding population is concentrated, the floor area is small, and the amount of sewage discharge is small. Compared with general hospitals, due to site restrictions, limited investment and The reason for the dispersion of sewage volume is that many institutions have not yet developed supporting treatment facilities, or the treatment standards are low, ...

AI Technical Summary

Problems solved by technology

[0004] In the existing technology, hospital sewage treatment will be treated in parallel with chlorine gas disinfection and dosing treatment. Gas will be generated during the sewage treatment process. After the disinfection is completed, bacteria and pathogens in the water will be eliminated by chlorine gas, and then However, the existing sewage treatment technology does not have the controllable function of residual chlorine, and cannot respond to chlorine gas in real time, which will easily lead to the problem of excessive residual chlorine. Therefore, there is an urgent need for a residual chlorine content detection and addition. integrated device
