Technical Field

Background

The Medical Laboratory (MLS) is a science that provides information for preventing, diagnosing, treating human diseases and evaluating human health by performing microbiological, immunological, biochemical, genetic, hematological, biophysical, cytological, etc. tests on materials taken from the human body, however, the wastewater generated after the medical test has various complex wastewater characteristics, including a large amount of microorganisms and a part of which may contain heavy metals, etc., and thus requires a specific treatment before being mixed into a sewer to enter a sewage treatment station in a collection and discharge stage, and a large amount of medical wastewater is generated by a large number of test instruments in the process of detecting specimens of blood, urine, feces, cerebrospinal fluid, etc., and carries a large amount of bacteria, viruses, parasitic ova, etc., which are extremely dangerous infection sources. Although most hospitals are provided with storage containers such as harmful wastewater collection barrels in relevant clinical laboratories, most hospitals and hospitals are provided with a large number of patients, so that daily test wastewater is metered by taking tons as a unit, the collection and treatment stage is very inconvenient, most hospitals are transferred to a special hospital medical wastewater treatment station for disinfection treatment after directly discharging a sewage pipeline, and then the hospital medical wastewater treatment station does not meet the requirements of relevant national regulations, and medical wastewater in a medical laboratory needs to be disinfected and discharged on site due to the requirements of relevant medical laboratory biosafety standards of the national health administration.

For example, the invention relates to a medical wastewater instant automatic disinfection treatment device (application number: CN 201810089026.6) in a medical laboratory, when medical wastewater generated by a medical laboratory inspection instrument flows through a medical wastewater discharge pipeline 7, three pairs of liquid level sensors inserted on the medical wastewater discharge pipeline 7 can be sequentially in conductive communication, signals are transmitted to a system control box 13, the system control box 13 sends an instruction to start a metering pump 11, disinfectant in a disinfectant bottle 10 is added into the medical wastewater discharge pipeline 7, and the disinfectant and the flowing medical wastewater are mixed, disinfected and discharged. When the medical laboratory inspection instrument stops working, no medical wastewater is generated, the three pairs of medical wastewater probes cannot be in conductive communication, and the metering pump 11 stops working; although a plurality of sensors and system control boxes are adopted to realize multi-stage control type sewage treatment, the control stage is only the disinfection control of the disinfection stage, and whether the wastewater treatment of different treatment stages is sufficient or not cannot be realized, and meanwhile, the treatment stage cannot be adjusted according to the flow of the treated wastewater, so that the treatment flow is sufficiently shortened.
