Industrial wastewater treatment process simulation experimental device

In order to understand the unit operation technology commonly used in industrial wastewater, master the processing process composed of these units, and observe the actions of wastewater, sludge and --r in the process of treatment. It is particularly experimental device for scientific research and teaching development of water treatment. The entire set of device is automatically controlled by the inflow of its wastewater, adding medicines, aeration, anti -flushing, emissions, and mud, etc. of its wastewater. Monitor each section of the water treatment effect, the whole set of equipment is used to use, can also be used separately, and each sewage pool has a development sample.
