For medical wastewater, its source composition is very complex, including toxic and harmful chemical pollutants and radioactive pollution, etc. All of these have various infectious characteristics. It mainly comes from some wastewater discharged from the laboratories, wards, laundry, X-ray photography rooms, and operating rooms in hospitals. How should medical wastewater be classified and treated? This article will introduce relevant issues together with you!

Compared with domestic and industrial wastewater, the impact of medical wastewater on the environment is still significant. If medical wastewater containing harmful substances such as viruses is discharged directly without undergoing some harmless treatments such as disinfection and inactivation, it will cause environmental pollution such as water and soil pollution. The discharge of medical wastewater is very complex and must be handled carefully. It can be classified and treated in the following three ways:

1.In each department of the hospital, the functions, facilities, and personnel composition are different. Medical wastewater mainly comes from various departments generating heavy metals, oily, reflective wastewater, etc. The wastewater generated by different types of hospitals will also be different. If it is an infectious disease hospital, the wastewater treatment situation will be more complex;

2.Related to staff and patients, mainly some domestic wastewater generated by various departments, such as hand washing, laundry, etc., which are related to life. According to statistics from relevant departments, each hospital bed can generate 0.8 tons of domestic wastewater. These wastewater also need to be treated before being discharged, otherwise it will cause certain harm;

3.In the hospital, drugs are certainly indispensable. During the production of drugs, wastewater is also generated. For the wastewater produced by drug production, it can be classified into the following two situations:

1) Firstly, the biological synthesis products are produced through microbial fermentation to produce various antibiotics and other drugs. The wastewater produced subsequently mainly contains biological synthesis metabolites, and in addition, there are residual nutrients and organic solvents in the mycelium;

2) There are also chemical synthesis products. Drugs and drug intermediates produced through chemical synthesis methods are contained in these wastewater, and they contain a wide variety of chemical substances.

Of course, during the treatment process of medical wastewater, various indicators in the water need to be detected and controlled. To do a good job in the online monitoring of medical wastewater, the main monitoring indicators include: coliform bacteria, total residual chlorine, COD, total phosphorus, total nitrogen, ammonia nitrogen, etc. Among them, coliform bacteria is an important indicator in the medical wastewater monitoring. We can use the WECT-900 Coliform Bacteria Online Analyzer to conduct real-time monitoring of it. Other parameters also have corresponding monitoring instruments.
