Medical sewage non-blocking circulation pretreatment device and method based on gas-liquid two-phase cooperative control

Abstract

The invention discloses a medical sewage non-blocking circulation pretreatment device and method based on gas-liquid double-phase cooperative control. In the device, a controller is connected with a liquid level sensor, a gas sensor, a water valve, a gas valve, a dosing execution module and a gas operation device. The liquid level heights in the first container and the second container are obtained by receiving data of the liquid level sensor, and the gas pressures in the first container, the second container and the third container are obtained by receiving data of the gas sensor, so that opening or closing of the water valve and the gas valve is controlled, and a set of gas-liquid dual-cooperative control device is constructed. The non-blocking flow guide of the liquid under the condition of no mechanical direct contact is realized. According to the medical sewage pretreatment device, on the basis that non-blocking circulation of medical sewage is achieved, pre-disinfection and dechlorination treatment on the medical sewage are achieved, it is guaranteed that the medical sewage is automatically and efficiently treated at low cost, and social public health safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical wastewater pretreatment, in particular to a non-blocking flow pretreatment device and method for medical wastewater based on gas-liquid two-phase coordinated control. Background technique [0002] Inpatient and outpatient departments in medical institutions produce a large amount of sewage in their daily work. [0003] Due to the particularity that medical sewage may carry a variety of pathogenic microorganisms and viruses, in order to avoid becoming a trigger point for public health safety accidents, according to relevant regulations, this part of sewage must be pre-disinfected before entering septic tanks, biochemical treatment and subsequent treatment. Eliminate security risks. [0004] The pre-disinfection of medical sewage needs to react with specific agents in a certain container for a certain period of time. [0005] In actual operation, during this pre-disinfection reaction time, due to ...

AI Technical Summary

Problems solved by technology

[0005]In actual operation, during this pre-disinfection reaction time, due to the slow flow of sewage, a large amount of solid impurities contained in medical sewage will precipitate, blocking the pre-disinfection container, Pipelines, etc., resulting in a large amount of maintenance work and cost
