We understand that the hospital is a public place for patients with various diseases to be treated, and the hospital will discharge a large amount of sewage every day, in addition to a large number of bacteria and viruses parasite eggs, but also BOD5/CODcr/SS and other pollution factors, so it is very important to install water quality monitoring instruments in the hospital to monitor its sewage.
Sewage Monitoring Methods:
Its monitoring can be mainly divided into two kinds, one is the online monitoring of water quality, the other is the laboratory analysis.
1.water quality online monitoring is an automatic water quality monitoring instrument achieved by online means, it uses modern sensor technology, automatic measurement technology, automatic control technology, computer application technology and related special analysis software and communication network, can get the current water quality data in real time. After a short period of data collection, the water quality information of the water source can be sent to the server of the Environmental Analysis Center. If the concentration of a certain pollutant is observed to change, the environmental regulatory authorities can immediately take corresponding measures. Real-time automatic monitoring of water quality can realize real-time continuous monitoring of water quality, achieve and grasp the water quality status of key sections of major river basins, early warning and forecasting of major or regional water pollution accidents, solve disputes over cross-administrative water pollution accidents, supervise the total amount control system, discharge standards and other purposes.
2.The traditional environmental water quality monitoring work is mainly based on manual field sampling and laboratory instrument analysis. Although the analytical means in the laboratory are complete, there are some defects in laboratory monitoring, such as low monitoring frequency, difficult sample preservation, large sampling error, scattered monitoring data, and inability to reflect pollution changes in time, which is difficult to meet the needs of governments and enterprises for effective water environment management.
Medical Wastewater Online Monitoring System:
1.Monthly hospital sewage monitoring items: pH, COD, ammonia nitrogen, Escherichia coli, residual chlorine, etc. (Parameters can be adjusted according to the actual needs of local environmental protection departments), but also flow monitoring to calculate pollutant flux.
2.According to the hospital needs and site conditions, the water quality online monitoring system to be installed at the hospital water treatment outlet is as follows:
3.Necessary monitoring instruments: COD online monitor, ammonia nitrogen online monitor, E. coli online analyzer, etc.
4.Online monitoring room and auxiliary facilities: standard station room (25㎡, water and electricity, air conditioning room temperature), lightning protection measures, open channel, Basher trough, pipe valve parts.
5.All devices are equipped with 4 ~ 20mA, RS232 or RS485 output interfaces, which can be connected to the data acquisition instrument and upload the data to the monitoring platform of the Environmental Protection Bureau.
