We know that medical wastewater is actually a low-concentration wastewater, which in addition to organic and inorganic pollutants (various drugs, disinfectants, anatomical waste and other pollutants), but also contains a large number of bacteria, viruses and parasites, the composition is very complex. If the waste water is discharged directly without treatment, it will cause serious pollution to the surrounding waters or soil. In this way, the safe treatment of medical wastewater, so that water quality monitoring can be less necessary! This chapter will help you understand the common problems in medical wastewater water quality monitoring as follows:
1.In the hospital, the number of patients fluctuates to a certain extent, and people come and go every day, so the discharge of wastewater will also fluctuate, and the timed and quantitative drug dosing machine cannot adjust the dosage according to the increase or decrease of the discharge of wastewater in time. The lag of the staff and many other aspects lead to problems such as substandard residual chlorine and excessive coliform number when the medical wastewater is discharged (the water quality can be monitored by the total residual chlorine online analyzerand the coliform online analyzer in the water to see whether the standard is exceeded);
2.The chemicals used are strongly corrosive, and long-term use can easily lead to the damage of the pipeline and lead to the discontinuation of the drug delivery unit. Even if the pipeline is washed with water on time, it can only be said that the corrosion resistance time of the pipeline can be extended, and the problem can not be fundamentally solved. If the logistics department can’t fix it in time, resulting in the direct discharge of waste water without disinfection, although the frequency of occurrence is rare, it does not mean that the problem does not exist.
3.Because the wastewater treatment center is more complex and many things, daily and monthly need to test a lot of data, monthly environmental hygiene sampling a day to sample three, and the cooperation between wastewater workers is very important, remember the daily work ideas to be clear, otherwise the work is easy to miss.
