The automatic control system for wastewater treatment can efficiently realize the treatment of industrial wastewater, without the need for too many workers to monitor on site, and avoids the safety problems caused by the volatilization of harmful substances in sewage. The entire wastewater treatment automatic control system includes:

1. On-site control box

2. Various sensors

3. PLC control cabinet

4. Complete set of distribution cabinets

5. HD camera, etc.

To realize the automatic control of this system, the selection of PLC in the PLC control cabinet must not be sloppy. In order to be able to flexibly change the IO according to the needs of the project, a plug-in type scalable PLC is recommended here. A master controller can connect dozens of IO plugs to realize the expansion of hundreds of local and remote IOs.
