1. My previous unit had state-controlled pollution sources and online monitoring. Our on-line monitoring is installed in the sewage outlet of my unit and connected with the environmental protection bureau. The data it monitors will be automatically transmitted to the Municipal Environmental Protection Bureau every two hours. This kind of real-time transmission with external related units is called online monitoring. The future trend is to use the online monitoring of wastewater discharge and concentration reported to the Environmental Protection Bureau to calculate the total amount of sewage discharged by your unit and collect sewage charges. Exceeding the standard can be fined according to the data of online monitoring.

2. In our sewage treatment system, such as the PH detector in the aerobic tank, the data are also generated in real time, but these data are only used for checking records and guiding the following dosage. We call it automatic detection.
