When it comes to the issue of medical wastewater prevention and control, the relevant authorities have always attached great importance to it! Even so, the management of medical wastewater discharge in urban and rural areas still needs to be strengthened. How can we start to talk about this? Let’s begin from here!
Regarding the management of medical wastewater discharge, it is an important “journey” of social civilization progress and scientific and technological progress. Strengthening the protection of water resources and the ecological civilization work is the responsibility that society should undertake. For urban and rural medical wastewater, if the discharge management is not done properly, it will bring certain risks to the ecological environment and human health.
Perhaps everyone has already known the main sources of medical wastewater! It mainly comes from places such as hospital wards, laundry, X-ray photography rooms, and operating rooms where wastewater is discharged. The composition of these can be quite complex. If it is discharged directly without treatment, it will affect the large water resources environment, and in serious cases, it will cause the spread of infectious diseases, thereby endangering human health!
How to Strengthen the Management of Medical Wastewater Discharge in Urban and Rural Areas?
1.Increase investment of funds, so that the construction of medical wastewater treatment facilities can be accelerated. Then, on this basis, use the sodium hypochlorite method to disinfect and sterilize the viruses in the medical wastewater, ensuring that the medical wastewater is discharged in accordance with standards. One thing to note here is that when using the sodium hypochlorite method for disinfection, another thing that needs to be done is to install an RCl900 Total Residual Chlorine Online Analyzer at the outlet to monitor the residual amount of the disinfectant, to ensure that there is no excessive total residual chlorine.
2.While doing publicity work, also increase the supervision of medical wastewater discharge. Especially in special situations, such as the outbreak of the 2019 novel coronavirus epidemic, the purpose of the publicity is to let everyone understand how great the infectious hazard brought by the epidemic is, and then how to do a good job in epidemic prevention work, thereby enhancing everyone’s risk prevention awareness. In addition, the staff of environmental protection departments at all levels need to conduct comprehensive quality monitoring throughout the process, do the disinfection and sterilization of medical wastewater, and also increase the frequency of medical wastewater online monitoring to ensure the safety of water quality. Achieve stable and compliant discharge of medical wastewater, ensure that the discharge facilities of medical wastewater are implemented properly, and ensure that the various indicators of the effluent are qualified.
So, What Indicators does Medical Eastewater need to be Tested for? And Which Monitoring Instruments are Used?
In addition to the total residual chlorine mentioned above, the medical wastewater also needs to be monitored for indicators such as pH value, suspended solids, ammonia nitrogen, chemical oxygen demand, total phosphorus, and coliform bacteria.
As for which monitoring instruments to use? Different projects use different instruments. The first few can be considered as some routine detection items, not only in medical wastewater, but also in many other wastewater in other places. Here, we mainly introduce the instrument for detecting coliform bacteria. Coliform bacteria grow in the intestines of living warm-blooded animals and will be excreted along with feces into the wastewater, which is a very important indicator for medical wastewater monitoring.
The WECT-900 Coliform Bacteria Online Analyzer uses the enzyme substrate method. The main process is that through the reaction of enzymes and bacteria, the change in light signals becomes proportional, thereby reflecting the total amount of coliform bacteria in the water. This instrument is a large coliform bacteria detection system based on biosensing technology, which can be said to be a very good detection method for dealing with water pollution.
