Abstract :
Industrial wastewater of a chemical plant is tannery wastewater. Its main components are polymer complex, benzene derivatives and hexavalent chromium. It is organic wastewater which is hard to be degraded and has poor biodegradability. Here we describe a complete technology of wastewater treatment system, automatic control system base on PLC and their commissioning and operation. Practice has proved that the system is stable and reliable and the outlet water quality is also good.
