Device and method for detecting medical wastewater

Abstract

The invention provides a method for detecting medical wastewater. The method comprises the following steps of: (A1) collecting medical wastewater to be detected, and adding a culture medium into the medical wastewater to be detected; (A2) irradiating light emitted by a light source into a mixed liquid of the medical wastewater to be detected and the culture medium; converting light signals of the mixed liquid, which are received by a detector, into electric signals and transmitting the electric signals to a judgment sub-module and a calculation sub-module, wherein the electric signals correspond to detection time; (A3) judging whether the medical wastewater to be detected meets a sterilization requirement according to a variation tendency of the received electric signals within a pre-judging period, and transmitting a judgment result to the calculation sub-module by an analyzing module; and (A4) when the received judging result is yes, calculating a concentration of a colony to be detected in the medical wastewater to be detected according to the follow-up received electric signals by the calculation sub-module. The method disclosed by the invention has the advantages of strong instruction meanings, short detection time, high accuracy and the like.

Description

technical field [0001] The invention relates to water detection, in particular to a detection device and method for medical wastewater. Background technique [0002] Medical wastewater is one of the most potentially harmful sewage with a large amount of daily discharge. It contains a large number of pathogenic microorganisms such as bacteria, viruses, and parasites. Most of the total number of bacteria in medical wastewater reaches several million to tens of millions per milliliter. The number of coliform bacteria per milliliter of sewage is mostly more than 200,000, and the detection rate of intestinal pathogenic bacteria reaches 30%-100%. Hospitals discharge hundreds of tons of medical wastewater containing contaminating pathogenic bacteria every day. If the wastewater is not timely Taking liquid chlorine disinfection, sodium hypochlorite disinfection or bleaching powder disinfection and other treatment measures, without effective microbial indicator monitoring, will cause...

Problems solved by technology

However, the above-mentioned water quality coliform on-line monitor is mainly used for water environment monitoring, and the application characteristics of medical wastewater are not considered enough: the above-mentioned instrument can only evaluate the quality of medical wastewater through the final test results of fecal coliform, and does not have the ability to disinfect or not. Due to the early prediction method and function of the system, it still takes several hours to obtain the evaluation result of the undisinfected wastewater, so that a large amount of medical wastewater is discharged during the detection period, which seriously affects the environmental quality and human health.
