We know that medical sewage is more complicated than ordinary domestic sewage. It contains a variety of components such as reagent waste, pathogens, microorganisms, and organic matter. The sewage can only be discharged into the pipeline after passing the inspection. Many hospitals, especially temporary hospitals, have limited equipment. How to do a good job in medical sewage detection? With the advancement of science and technology, workers no longer need to collect water samples, store them frozen, and send them to a third-party testing agency for inspection.

There is an effective method for testing water quality in the industry, which is to put chlorine in water samples. After a certain period of contact, bacteria, microorganisms, organics, and inorganic substances in the water will react and consume a part of the amount of chlorine. The amount of chlorine will know whether the water quality has reached the discharge standard.
In sharp contrast to the original urban sewage treatment system, hospital sewage treatment under epidemic prevention and control has the characteristics of "emergency", "temporary" and "uncertainty". As an important part of controlling the epidemic, hospitals play an extremely important role. Front-line medical workers struggled day and night, the continuous increase in the number of discharged patients and the continuous decrease in the number of new infections, let us see the hope of successful anti-epidemic.
As front-line medical workers work hard to fight the epidemic, we should pay more attention to disinfection at the source to prevent the spread of the virus. In terms of disinfection treatment, the staff should strictly disinfect the sewage in accordance with the medical waste water treatment specifications and related requirements, and then discharge the water after the water quality tester has reached the standard.
