Medical wastewater is a kind of low-concentration wastewater. After removing organic and inorganic pollutants, it also contains a large number of complex components such as bacteria, pathogens and parasites. If these wastewaters are discharged directly without treatment, they will cause serious pollution to the surrounding waters or soil. So it must be safely handled before being discharged! Real-time water quality detection is an important link in the water quality treatment process. In this chapter, the editor will learn with you several problems that may be encountered in the monitoring process of medical wastewater!

1.In hospitals, it is quite common for the inflow and outflow of patients to fluctuate. The inflow and outflow of such different patients will also cause corresponding changes in the amount of wastewater discharged. If the staff fail to adjust the dosage of the prescribed drugs in a timely manner according to the increase or decrease in the amount of wastewater discharged, or if there is a lag in operation, it will lead to problems such as the residual chlorine not meeting the standard and the coliform bacteria count exceeding the standard when medical wastewater is discharged.

2.If the chemicals used are highly corrosive, long-term use can easily cause damage to the pipelines, leading to the shutdown of the dosing unit. Even if there are staff members who clean them regularly, it only prolongs the corrosion resistance time of the pipelines and cannot fundamentally solve the problem. If the staff fail to repair it in time, the wastewater will be discharged without disinfection, and the consequences will be unimaginable!

3.Due to the numerous matters involved in wastewater treatment, data needs to be tested every day or every month. Three environmental hygiene samples are collected each day. Therefore, the mutual cooperation among the staff is particularly important. During the work period, it is necessary to ensure a clear mind to avoid mistakes that may cause trouble to the work!
