In fact, in many situations, as long as the work is done properly, there is nothing to be afraid of. Take medical wastewater, for example. It has always been emphasized that hospitals are complex environments with contamination from various pathogens—just thinking about it can be frightening. However, if proper medical wastewater treatment is carried out, and online monitoring is conducted before discharge to ensure that all indicators meet the standards, then there is really nothing to fear!
The main pollutants in medical wastewater include pathogenic microorganisms (such as bacteria), harmful and toxic physical and chemical pollutants, some radioactive pollutants, as well as conventional pollutants (like BOD, COD, ammonia nitrogen, etc.). If medical wastewater treatment is properly implemented to ensure that all indicators meet discharge standards, you won’t find it scary! Pay attention to the following tasks:
1.Establish clear tasks and assign responsibilities—don’t wait until the last minute. Ensure that every staff member knows their role and “fulfills their duties in their position.”
2.Strictly follow the wastewater treatment procedures to ensure that all parameters of the wastewater treatment facilities are normal (if necessary, the operation of the wastewater treatment facilities can be outsourced to a third party).
3.Regularly inspect the relevant equipment of key treatment units. If any issues are found, address them promptly to ensure a 95% equipment integrity rate.
4.Properly disinfect the medical wastewater and conduct repeated checks without relaxation. Discharge of inadequately disinfected wastewater is strictly prohibited. Especially during the pandemic, after disinfecting fecal wastewater, an Online Coliform Analyzer should be used to monitor the coliform content in the wastewater in real time.
5.Conduct daily real-time monitoring of conventional indicators in the wastewater, such as COD, ammonia nitrogen, and total nitrogen, to ensure compliance with relevant standards. For urban treatment plants receiving upstream medical wastewater, disinfectants should be added based on actual conditions to enhance wastewater disinfection. If chlorine disinfection is used, the amount of chlorine added must be carefully controlled to avoid hazards caused by excessive chlorine levels!
