In complex places like hospitals, the relevant departments are more strict about the discharge of medical wastewater. For this reason, medical wastewater must be discharged under the condition of meeting the standards. Once it is found that the wastewater is discharged directly without treatment or that the disinfected wastewater is discharged without meeting the standards through the medical wastewater online monitoring , penalties will be imposed. In this article, we mainly aim to learn about 10 points to remember when disinfecting medical wastewater!
1.It is necessary to do a good job in the daily management of wastewater treatment, implement safety management measures well, and at the same time establish a contingency plan for unexpected accidents during the wastewater treatment process. In addition, each job position personnel should implement well to avoid some unnecessary troubles in the process of medical wastewater treatment.
2.Staff dealing with wastewater need to be trained to master the knowledge of wastewater disinfection treatment and safety management. In addition, the attire must meet the requirements before work can be carried out.
3.It is necessary to set up proper wastewater treatment facilities, collect and disinfect the generated wastewater, and then monitor the disinfected wastewater to see if all indicators meet the standards. Only after confirming that they meet the standards should it be discharged.
4.Regarding wastewater treatment facilities, measures such as anti-seepage, anti-freezing and anti-corrosion should be taken to ensure the safety and durability of these facilities. The facilities should be covered to prevent theft or children who don’t understand and touch them randomly. Also, doing a good job in cleaning is an essential task for the maintenance of any instrument or equipment. In addition, a disinfection sampling port is set up at the outlet of the disinfection tank in the wastewater treatment facility, and the various indicators of the wastewater are monitored in real time through a water quality monitor.
5.Whether it is automatic or manual disinfection, the measurement must be accurate to meet the disinfection requirements of wastewater.
6.After adding the disinfectant, the contact time between the disinfectant and the wastewater should be more than one hour. If the wastewater is treated and disinfected by a disinfection machine, please use it according to the instructions and keep a record of the wastewater disinfection treatment.
7.The disinfectant should be prepared in sufficient quantities (keep a record when purchasing for future reference), and then for its storage, it should be kept in a well-ventilated, cool, dark and dry place.
8.Do a good job in online monitoring of medical wastewater. If you are disinfecting with chlorine-containing disinfectants, at the same time, you need to configure a total residual chlorine online analyzer that meets the requirements, install it at the outlet of the contact tank, monitor the amount of chlorine disinfectant added in real time, and keep records. Ensure that the wastewater is discharged in compliance with relevant standards. According to the requirements of the GB18466 standard, in addition to monitoring the total residual chlorine, it is also necessary to monitor the coliform bacteria and other microorganisms in the disinfected wastewater. Only when all these indicators meet the prescribed discharge standards can it be discharged into the sewage treatment system for further treatment!
