When it comes to coliform bacteria, it is an important indicator for monitoring medical wastewater. The level of coliform bacteria in the wastewater is used to determine the degree of water pollution. If the coliform bacteria in the medical wastewater are not properly treated, and if the test results show severe over-limitations, it will pose a safety hazard to everyone. Sometimes there may be no obvious impact, but over time, problems will gradually emerge. All of this is due to the poor performance of disinfection and sterilization treatment.
Although the relevant departments are paying increasing attention to the monitoring of wastewater and sewage, there are still some cases of excessive discharge of coliform bacteria in wastewater. This is because the wastewater is not treated properly before discharge or the treatment effect is poor. Without further observation and treatment, it is directly discharged. This is done for the sake of convenience, seeking temporary ease, but it causes pollution to other water sources and even poses risks to human health. For example: The standard for coliform bacteria in wastewater from sewage treatment plants is set according to the B standard in the pollutant discharge standards of urban sewage treatment plants. That is to say, the number of coliform bacteria in the discharged wastewater should be lower than 10,000 per liter. Exceeding this value is considered as over-limitation. This indicates that the water treatment is not thorough enough.
Coliform bacteria is a conventional bacterial indicator. Its main source is human and livestock feces. The domestic sewage produced by humans and livestock needs to be centrally treated by a treatment plant. After testing these waters to ensure the indicators are qualified, they can be discharged. The disinfection process set here can effectively control the indicators of fecal coliform bacteria. If it is drinking water, it will be purified by a water treatment plant and then tested by a water quality monitoring instrument to confirm that the indicators are qualified before being consumed.
The instrument used to detect coliform bacteria in wastewater can be the WECT-900 Coliform Bacteria Online Analyzer. This instrument is a fully automatic water quality monitoring device mainly used for the monitoring of drinking water and medical wastewater.
